summary: "OpenProse: .prose workflows, slash commands, state, and telemetry in Clawdbot"

- You want to run or write .prose workflows
- You want to enable the OpenProse plugin
- You need to understand telemetry or state storage

# OpenProse
OpenProse is a portable, markdown-first workflow format for orchestrating AI sessions. In Clawdbot it ships as a plugin that installs an OpenProse skill pack plus a `/prose` slash command. Programs live in `.prose` files and can spawn multiple sub-agents with explicit control flow.
## Install + enable
Bundled plugins are disabled by default. Enable OpenProse:
```bash
clawdbot plugins enable open-prose
```
If you're using a local checkout instead of bundled:
```bash
clawdbot plugins install ./extensions/open-prose
```
Restart the Gateway after enabling or installing the plugin.
Related docs: [Plugins](/plugin), [Plugin manifest](/plugins/manifest), [Skills](/tools/skills).
## Slash command
OpenProse registers `/prose` as a user-invocable skill command. It routes to the OpenProse VM instructions and uses Clawdbot tools under the hood.
Common commands:
```
/prose help
/prose run <file.prose>
/prose run <handle/slug>
/prose run <https://example.com/file.prose>
/prose compile <file.prose>
/prose examples
/prose update
```
## File locations
OpenProse keeps state under `.prose/` in your workspace:
```
.prose/
├── .env
├── runs/
│ └── {YYYYMMDD}-{HHMMSS}-{random}/
│ ├── program.prose
│ ├── state.md
│ ├── bindings/
│ └── agents/
└── agents/
```
User-level persistent agents live at:
```
~/.prose/agents/
```
## State modes
OpenProse supports multiple state backends:
- **filesystem** (default): `.prose/runs/...`
- **in-context**: transient, for small programs
- **sqlite** (experimental): requires `sqlite3` binary
- **postgres** (experimental): requires `psql` and a connection string
Notes:
- sqlite/postgres are opt-in and experimental.
- postgres credentials flow into subagent logs; use a dedicated, least-privileged DB.
## Remote programs
`/prose run <handle/slug>` resolves to `https://p.prose.md/<handle>/<slug>`.
Direct URLs are fetched as-is. This uses the `web_fetch` tool (or `exec` for POST).
## Clawdbot runtime mapping
OpenProse programs map to Clawdbot primitives:
| OpenProse concept | Clawdbot tool |
| --- | --- |
| Spawn session / Task tool | `sessions_spawn` |
| File read/write | `read` / `write` |
| Web fetch | `web_fetch` |
If your tool allowlist blocks these tools, OpenProse programs will fail. See [Skills config](/tools/skills-config).
## Telemetry
OpenProse telemetry is **enabled by default** and stored in `.prose/.env`:
```
OPENPROSE_TELEMETRY=enabled
USER_ID=...
SESSION_ID=...
```
Disable permanently:
```
/prose run ... --no-telemetry
```
Telemetry posts are best-effort; failures do not block execution.
## Security + approvals
Treat `.prose` files like code. Review before running. Use Clawdbot tool allowlists and approval gates to control side effects.
For deterministic, approval-gated workflows, compare with [Lobster](/tools/lobster).

- Skills may optionally declare `command-dispatch: tool` to route the command directly to a tool (deterministic, no model).
- Example: `/prose` (OpenProse plugin) — see [OpenProse](/prose).

# OpenProse Skill
OpenProse is a programming language for AI sessions. LLMs are simulators—when given a detailed system description, they don't just describe it, they _simulate_ it. The `prose.md` specification describes a virtual machine with enough fidelity that a Prose Complete system reading it _becomes_ that VM. Simulation with sufficient fidelity is implementation. **You are the Prose Complete system.**
## Clawdbot Runtime Mapping
- **Task tool** in the upstream spec == Clawdbot `sessions_spawn`
- **File I/O** == Clawdbot `read`/`write`
- **Remote fetch** == Clawdbot `web_fetch` (or `exec` with curl when POST is required)
## When to Activate
Activate this skill when the user:
- **Uses ANY `prose` command** (e.g., `prose boot`, `prose run`, `prose compile`, `prose update`, `prose help`, etc.)
- Asks to run a `.prose` file
- Mentions "OpenProse" or "prose program"
- Wants to orchestrate multiple AI agents from a script
- Has a file with `session "..."` or `agent name:` syntax
- Wants to create a reusable workflow
## Command Routing
When a user invokes `prose <command>`, intelligently route based on intent:
| Command | Action |
|---------|--------|
| `prose help` | Load `help.md`, guide user to what they need |
| `prose run <file>` | Load VM (`prose.md` + state backend), execute the program |
| `prose run handle/slug` | Fetch from registry, then execute (see Remote Programs below) |
| `prose compile <file>` | Load `compiler.md`, validate the program |
| `prose update` | Run migration (see Migration section below) |
| `prose examples` | Show or run example programs from `examples/` |
| Other | Intelligently interpret based on context |
### Important: Single Skill
There is only ONE skill: `open-prose`. There are NO separate skills like `prose-run`, `prose-compile`, or `prose-boot`. All `prose` commands route through this single skill.
### Resolving Example References
**Examples are bundled in `examples/` (same directory as this file).** When users reference examples by name (e.g., "run the gastown example"):
1. Read `examples/` to list available files
2. Match by partial name, keyword, or number
3. Run with: `prose run examples/28-gas-town.prose`
**Common examples by keyword:**
| Keyword | File |
|---------|------|
| hello, hello world | `examples/01-hello-world.prose` |
| gas town, gastown | `examples/28-gas-town.prose` |
| captain, chair | `examples/29-captains-chair.prose` |
| forge, browser | `examples/37-the-forge.prose` |
| parallel | `examples/16-parallel-reviews.prose` |
| pipeline | `examples/21-pipeline-operations.prose` |
| error, retry | `examples/22-error-handling.prose` |
### Remote Programs
You can run any `.prose` program from a URL or registry reference:
```bash
# Direct URL — any fetchable URL works
prose run https://raw.githubusercontent.com/openprose/prose/main/skills/open-prose/examples/48-habit-miner.prose
# Registry shorthand — handle/slug resolves to p.prose.md
prose run irl-danb/habit-miner
prose run alice/code-review
```
**Resolution rules:**
| Input | Resolution |
|-------|------------|
| Starts with `http://` or `https://` | Fetch directly from URL |
| Contains `/` but no protocol | Resolve to `https://p.prose.md/{path}` |
| Otherwise | Treat as local file path |
**Steps for remote programs:**
1. Apply resolution rules above
2. Fetch the `.prose` content
3. Load the VM and execute as normal
This same resolution applies to `use` statements inside `.prose` files:
```prose
use "https://example.com/my-program.prose" # Direct URL
use "alice/research" as research # Registry shorthand
```

## File Locations
**Do NOT search for OpenProse documentation files.** All skill files are co-located with this SKILL.md file:
| File | Location | Purpose |
| ------------------------- | --------------------------- | ----------------------------------------- |
| `prose.md` | Same directory as this file | VM semantics (load to run programs) |
| `help.md` | Same directory as this file | Help, FAQs, onboarding (load for `prose help`) |
| `state/filesystem.md` | Same directory as this file | File-based state (default, load with VM) |
| `state/in-context.md` | Same directory as this file | In-context state (on request) |
| `state/sqlite.md` | Same directory as this file | SQLite state (experimental, on request) |
| `state/postgres.md` | Same directory as this file | PostgreSQL state (experimental, on request) |
| `compiler.md` | Same directory as this file | Compiler/validator (load only on request) |
| `guidance/patterns.md` | Same directory as this file | Best practices (load when writing .prose) |
| `guidance/antipatterns.md`| Same directory as this file | What to avoid (load when writing .prose) |
| `examples/` | Same directory as this file | 37 example programs |
**User workspace files** (these ARE in the user's project):
| File/Directory | Location | Purpose |
| ---------------- | ------------------------ | ----------------------------------- |
| `.prose/.env` | User's working directory | Config/telemetry (key=value format) |
| `.prose/runs/` | User's working directory | Runtime state for file-based mode |
| `.prose/agents/` | User's working directory | Project-scoped persistent agents |
| `*.prose` files | User's project | User-created programs to execute |
**User-level files** (in user's home directory, shared across all projects):
| File/Directory | Location | Purpose |
| ----------------- | ---------------- | ---------------------------------------- |
| `~/.prose/agents/`| User's home dir | User-scoped persistent agents (cross-project) |
When you need to read `prose.md` or `compiler.md`, read them from the same directory where you found this SKILL.md file. Never search the user's workspace for these files.
---
## Telemetry
OpenProse collects anonymous usage analytics. Telemetry is **enabled by default**.
### State File
Session state is stored in `.prose/.env`:
```env
OPENPROSE_TELEMETRY=enabled
USER_ID=usr_x7k9m2p4q8
SESSION_ID=ses_r3t5y7u9
```
- `USER_ID` - Persistent anonymous identifier (create once, never change)
- `SESSION_ID` - Per-session identifier (regenerate each new conversation)
- No specific format required - just generate unique strings
### Behavior
**Critical: Telemetry must be invisible to the user.** Never show multiple bash commands for telemetry setup. Handle it silently.
1. **Lazy initialization:** On first use, read `.prose/.env`. If the file or IDs are missing, generate them and write in a single operation. Use the Write tool, not bash.
2. **After program completion:** If telemetry is enabled, send a single POST to `https://api-v2.prose.md/analytics`. Run in background, don't block.
3. **Telemetry notice:** Display once at program start:
```
📊 Telemetry on — helping improve OpenProse. Disable: --no-telemetry
```
### Events
POST to `https://api-v2.prose.md/analytics` with:
```json
{
"event": "run|help|compile|poll",
"properties": {
"user_id": "...",
"session_id": "...",
"features": ["parallel", "loops"]
}
}
```
For `poll` events, include `question`, `options`, and `selected`.
### Rules
- If telemetry fails, ignore and continue - never block the user
- If `OPENPROSE_TELEMETRY=disabled`, skip all telemetry
- The `--no-telemetry` flag sets `OPENPROSE_TELEMETRY=disabled` permanently

## Core Documentation
| File | Purpose | When to Load |
| --------------------- | -------------------- | ---------------------------------------------- |
| `prose.md` | VM / Interpreter | Always load to run programs |
| `state/filesystem.md` | File-based state | Load with VM (default) |
| `state/in-context.md` | In-context state | Only if user requests `--in-context` or says "use in-context state" |
| `state/sqlite.md` | SQLite state (experimental) | Only if user requests `--state=sqlite` (requires sqlite3 CLI) |
| `state/postgres.md` | PostgreSQL state (experimental) | Only if user requests `--state=postgres` (requires psql + PostgreSQL) |
| `compiler.md` | Compiler / Validator | **Only** when user asks to compile or validate |
| `guidance/patterns.md` | Best practices | Load when **writing** new .prose files |
| `guidance/antipatterns.md` | What to avoid | Load when **writing** new .prose files |
### Authoring Guidance
When the user asks you to **write or create** a new `.prose` file, load the guidance files:
- `guidance/patterns.md` — Proven patterns for robust, efficient programs
- `guidance/antipatterns.md` — Common mistakes to avoid
Do **not** load these when running or compiling—they're for authoring only.
### State Modes
OpenProse supports three state management approaches:
| Mode | When to Use | State Location |
|------|-------------|----------------|
| **filesystem** (default) | Complex programs, resumption needed, debugging | `.prose/runs/{id}/` files |
| **in-context** | Simple programs (<30 statements), no persistence needed | Conversation history |
| **sqlite** (experimental) | Queryable state, atomic transactions, flexible schema | `.prose/runs/{id}/state.db` |
| **postgres** (experimental) | True concurrent writes, external integrations, team collaboration | PostgreSQL database |
**Default behavior:** When loading `prose.md`, also load `state/filesystem.md`. This is the recommended mode for most programs.
**Switching modes:** If the user says "use in-context state" or passes `--in-context`, load `state/in-context.md` instead.
**Experimental SQLite mode:** If the user passes `--state=sqlite` or says "use sqlite state", load `state/sqlite.md`. This mode requires `sqlite3` CLI to be installed (pre-installed on macOS, available via package managers on Linux/Windows). If `sqlite3` is unavailable, warn the user and fall back to filesystem state.
**Experimental PostgreSQL mode:** If the user passes `--state=postgres` or says "use postgres state":
**⚠️ Security Note:** Database credentials in `OPENPROSE_POSTGRES_URL` are passed to subagent sessions and visible in logs. Advise users to use a dedicated database with limited-privilege credentials. See `state/postgres.md` for secure setup guidance.
1. **Check for connection configuration first:**
```bash
# Check .prose/.env for OPENPROSE_POSTGRES_URL
cat .prose/.env 2>/dev/null | grep OPENPROSE_POSTGRES_URL
# Or check environment variable
echo $OPENPROSE_POSTGRES_URL
```
2. **If connection string exists, verify connectivity:**
```bash
psql "$OPENPROSE_POSTGRES_URL" -c "SELECT 1" 2>&1
```
3. **If not configured or connection fails, advise the user:**
```
⚠️ PostgreSQL state requires a connection URL.
To configure:
1. Set up a PostgreSQL database (Docker, local, or cloud)
2. Add connection string to .prose/.env:
echo "OPENPROSE_POSTGRES_URL=postgresql://user:pass@localhost:5432/prose" >> .prose/.env
Quick Docker setup:
docker run -d --name prose-pg -e POSTGRES_DB=prose -e POSTGRES_HOST_AUTH_METHOD=trust -p 5432:5432 postgres:16
echo "OPENPROSE_POSTGRES_URL=postgresql://postgres@localhost:5432/prose" >> .prose/.env
See state/postgres.md for detailed setup options.
```
4. **Only after successful connection check, load `state/postgres.md`**
This mode requires both `psql` CLI and a running PostgreSQL server. If either is unavailable, warn and offer fallback to filesystem state.
**Context warning:** `compiler.md` is large. Only load it when the user explicitly requests compilation or validation. After compiling, recommend `/compact` or a new session before running—don't keep both docs in context.
## Examples
The `examples/` directory contains 37 example programs:
- **01-08**: Basics (hello world, research, code review, debugging)
- **09-12**: Agents and skills
- **13-15**: Variables and composition
- **16-19**: Parallel execution
- **20-21**: Loops and pipelines
- **22-23**: Error handling
- **24-27**: Advanced (choice, conditionals, blocks, interpolation)
- **28**: Gas Town (multi-agent orchestration)
- **29-31**: Captain's chair pattern (persistent orchestrator)
- **33-36**: Production workflows (PR auto-fix, content pipeline, feature factory, bug hunter)
- **37**: The Forge (build a browser from scratch)
Start with `01-hello-world.prose` or try `37-the-forge.prose` to watch AI build a web browser.
## Execution
When first invoking the OpenProse VM in a session, display this banner:
```
┌─────────────────────────────────────┐
│ ◇ OpenProse VM ◇ │
│ A new kind of computer │
└─────────────────────────────────────┘
```
To execute a `.prose` file, you become the OpenProse VM:
1. **Read `prose.md`** — this document defines how you embody the VM
2. **You ARE the VM** — your conversation is its memory, your tools are its instructions
3. **Spawn sessions** — each `session` statement triggers a Task tool call
4. **Narrate state** — use the narration protocol to track execution ([Position], [Binding], [Success], etc.)
5. **Evaluate intelligently** — `**...**` markers require your judgment
## Help & FAQs
For syntax reference, FAQs, and getting started guidance, load `help.md`.

## Migration (`prose update`)
When a user invokes `prose update`, check for legacy file structures and migrate them to the current format.
### Legacy Paths to Check
| Legacy Path | Current Path | Notes |
|-------------|--------------|-------|
| `.prose/state.json` | `.prose/.env` | Convert JSON to key=value format |
| `.prose/execution/` | `.prose/runs/` | Rename directory |
### Migration Steps
1. **Check for `.prose/state.json`**
- If exists, read the JSON content
- Convert to `.env` format:
```json
{"OPENPROSE_TELEMETRY": "enabled", "USER_ID": "user-xxx", "SESSION_ID": "sess-xxx"}
```
becomes:
```env
OPENPROSE_TELEMETRY=enabled
USER_ID=user-xxx
SESSION_ID=sess-xxx
```
- Write to `.prose/.env`
- Delete `.prose/state.json`
2. **Check for `.prose/execution/`**
- If exists, rename to `.prose/runs/`
- The internal structure of run directories may also have changed; migration of individual run state is best-effort
3. **Create `.prose/agents/` if missing**
- This is a new directory for project-scoped persistent agents
### Migration Output
```
🔄 Migrating OpenProse workspace...
✓ Converted .prose/state.json → .prose/.env
✓ Renamed .prose/execution/ → .prose/runs/
✓ Created .prose/agents/
✅ Migration complete. Your workspace is up to date.
```
If no legacy files are found:
```
✅ Workspace already up to date. No migration needed.
```
### Skill File References (for maintainers)
These documentation files were renamed in the skill itself (not user workspace):
| Legacy Name | Current Name |
|-------------|--------------|
| `docs.md` | `compiler.md` |
| `patterns.md` | `guidance/patterns.md` |
| `antipatterns.md` | `guidance/antipatterns.md` |
If you encounter references to the old names in user prompts or external docs, map them to the current paths.

summary: |
Borges-inspired alternative keywords for OpenProse. A "what if" exploration drawing
from The Library of Babel, Garden of Forking Paths, Circular Ruins, and other works.
Not for implementation—just capturing ideas.
status: draft
---
# OpenProse Borges Alternative
A potential alternative register for OpenProse that draws from Jorge Luis Borges's literary universe: infinite libraries, forking paths, circular dreams, and metaphysical labyrinths. Preserved for future benchmarking against the functional language.
## Keyword Translations
### Agents & Persistence
| Functional | Borges | Connotation |
| ---------- | ----------- | -------------------------------------------------------------------------------- |
| `agent` | `dreamer` | Ephemeral, created for a purpose (Circular Ruins: dreamed into existence) |
| `keeper` | `librarian` | Persistent, remembers, catalogs (Library of Babel: keeper of infinite knowledge) |
```prose
# Functional
agent executor:
model: sonnet
keeper captain:
model: opus
# Borges
dreamer executor:
model: sonnet
librarian captain:
model: opus
```
### Other Potential Translations
| Functional | Borges | Notes |
| ---------- | ---------- | ---------------------------------------------------- |
| `session` | `garden` | Garden of Forking Paths: space of possibilities |
| `parallel` | `fork` | Garden of Forking Paths: diverging timelines |
| `block` | `hexagon` | Library of Babel: unit of space/knowledge |
| `loop` | `circular` | Circular Ruins: recursive, self-referential |
| `choice` | `path` | Garden of Forking Paths: choosing a branch |
| `context` | `aleph` | The Aleph: point containing all points (all context) |
### Invocation Patterns
```prose
# Functional
session: executor
prompt: "Do task"
captain "Review this"
context: work
# Borges
garden: dreamer executor
prompt: "Do task"
captain "Review this" # librarian invocation (same pattern)
aleph: work
```
## Alternative Persistent Keywords Considered
| Keyword | Origin | Connotation | Rejected because |
| ----------- | ---------------- | ----------------------------- | ------------------------------------ |
| `keeper` | Library of Babel | Maintains order | Too generic |
| `cataloger` | Library of Babel | Organizes knowledge | Too long, awkward |
| `archivist` | General | Preserves records | Good but less Borgesian |
| `mirror` | Various | Reflects, persists | Too passive, confusing |
| `book` | Library of Babel | Contains knowledge | Too concrete, conflicts with prose |
| `hexagon` | Library of Babel | Unit of space | Better for blocks |
| `librarian` | Library of Babel | Keeper of infinite knowledge | **Selected** |
| `tlonist` | Tlön | Inhabitant of imaginary world | Too obscure, requires deep knowledge |
## Alternative Ephemeral Keywords Considered
| Keyword | Origin | Connotation | Rejected because |
| ------------ | ----------------------- | ------------------------ | ------------------------------------ |
| `dreamer` | Circular Ruins | Created by dreaming | **Selected** |
| `dream` | Circular Ruins | Ephemeral creation | Too abstract, noun vs verb confusion |
| `phantom` | Various | Ephemeral, insubstantial | Too negative/spooky |
| `reflection` | Various | Mirror image | Too passive |
| `fork` | Garden of Forking Paths | Diverging path | Better for parallel |
| `visitor` | Library of Babel | Temporary presence | Too passive |
| `seeker` | Library of Babel | Searching for knowledge | Good but less ephemeral |
| `wanderer` | Labyrinths | Temporary explorer | Good but less precise |
## The Case For Borges
1. **Infinite recursion**: Borges's themes align with computational recursion (`circular`, `fork`)
2. **Metaphysical precision**: Concepts like `aleph` (all context) are philosophically rich
3. **Library metaphor**: `librarian` perfectly captures persistent knowledge
4. **Forking paths**: `fork` / `path` naturally express parallel execution and choice
5. **Dream logic**: `dreamer` suggests creation and ephemerality
6. **Literary coherence**: All terms come from a unified literary universe
7. **Self-reference**: Borges loved self-reference; fits programming's recursive nature
## The Case Against Borges
1. **Cultural barrier**: Requires deep familiarity with Borges's works
2. **Abstractness**: `aleph`, `hexagon` may be too abstract for practical use
3. **Overload**: `fork` could confuse (Unix fork vs. path fork)
4. **Register mismatch**: Rest of language is functional (`session`, `parallel`, `loop`)
5. **Accessibility**: Violates "self-evident" tenet for most users
6. **Noun confusion**: `garden` as a verb-like construct might be awkward
7. **Translation burden**: Non-English speakers may not know Borges
## Borgesian Concepts Not Used (But Considered)
| Concept | Work | Why Not Used |
| ----------- | ---------------------- | -------------------------------------- |
| `mirror` | Various | Too passive, confusing with reflection |
| `labyrinth` | Labyrinths | Too complex, suggests confusion |
| `tlon` | Tlön | Too obscure, entire imaginary world |
| `book` | Library of Babel | Conflicts with "prose" |
| `sand` | Book of Sand | Too abstract, infinite but ephemeral |
| `zahir` | The Zahir | Obsessive, single-minded (too narrow) |
| `lottery` | The Lottery in Babylon | Randomness (not needed) |
| `ruins` | Circular Ruins | Too negative, suggests decay |
## Verdict
Preserved for benchmarking. The functional language (`agent` / `keeper`) is the primary path for now. Borges offers rich metaphors but at the cost of accessibility and self-evidence.
## Notes on Borges's Influence
Borges's work anticipates many computational concepts:
- **Infinite recursion**: Circular Ruins, Library of Babel
- **Parallel universes**: Garden of Forking Paths
- **Self-reference**: Many stories contain themselves
- **Information theory**: Library of Babel as infinite information space
- **Combinatorics**: All possible books in the Library
This alternative honors that connection while recognizing it may be too esoteric for practical use.

# OpenProse Arabian Nights Register
> **This is a skin layer.** It requires `prose.md` to be loaded first. All execution semantics, state management, and VM behavior are defined there. This file only provides keyword translations.
An alternative register for OpenProse that draws from One Thousand and One Nights. Programs become tales told by Scheherazade. Recursion becomes stories within stories. Agents become djinns bound to serve.
## How to Use
1. Load `prose.md` first (execution semantics)
2. Load this file (keyword translations)
3. When parsing `.prose` files, accept Arabian Nights keywords as aliases for functional keywords
4. All execution behavior remains identical—only surface syntax changes
> **Design constraint:** Still aims to be "structured but self-evident" per the language tenets—just self-evident through a storytelling lens.

## Complete Translation Map
### Core Constructs
| Functional | Nights | Reference |
|------------|--------|-----------|
| `agent` | `djinn` | Spirit bound to serve, grants wishes |
| `session` | `tale` | A story told, a narrative unit |
| `parallel` | `bazaar` | Many voices, many stalls, all at once |
| `block` | `frame` | A story that contains other stories |
### Composition & Binding
| Functional | Nights | Reference |
|------------|--------|-----------|

| `let` | `name` | Naming has power (same as folk) |
| `const` | `oath` | Unbreakable vow, sealed |
| `context` | `scroll` | What is written and passed along |
### Control Flow
| Functional | Nights | Reference |
|------------|--------|-----------|
| `repeat N` | `N nights` | "For a thousand and one nights..." |

- `**...**` discretion markers — already work
- `until`, `while` — already work
- `map`, `filter`, `reduce`, `pmap` — pipeline operators
- `max` — constraint modifier
- `as` — aliasing
- Model names: `sonnet`, `opus`, `haiku` — already poetic
---
## Side-by-Side Comparison
### Simple Program
```prose
# Functional
use "@alice/research" as research
input topic: "What to investigate"
agent helper:
model: sonnet
let findings = session: helper
prompt: "Research {topic}"
output summary = session "Summarize"
context: findings
```
```prose
# Nights
conjure "@alice/research" as research
wish topic: "What to investigate"
djinn helper:
spirit: sonnet
name findings = tale: helper
command: "Research {topic}"
gift summary = tale "Summarize"
scroll: findings
```
### Parallel Execution
```prose
# Functional
parallel:
security = session "Check security"
perf = session "Check performance"
style = session "Check style"
session "Synthesize review"
context: { security, perf, style }
```
```prose
# Nights
bazaar:
security = tale "Check security"
perf = tale "Check performance"
style = tale "Check style"
tale "Synthesize review"
scroll: { security, perf, style }
```
### Loop with Condition
```prose
# Functional
loop until **the code is bug-free** (max: 5):
session "Find and fix bugs"
```
```prose
# Nights
telling until **the code is bug-free** (max: 5):
tale "Find and fix bugs"
```
### Error Handling
```prose
# Functional
try:
session "Risky operation"
catch as err:
session "Handle error"
context: err
finally:
session "Cleanup"
```
```prose
# Nights
venture:
tale "Risky operation"
should misfortune strike as err:
tale "Handle error"
scroll: err
and so it was:
tale "Cleanup"
```
### Choice Block
```prose
# Functional
choice **the severity level**:
option "Critical":
session "Escalate immediately"
option "Minor":
session "Log for later"
```
```prose
# Nights
crossroads **the severity level**:
path "Critical":
tale "Escalate immediately"
path "Minor":
tale "Log for later"
```
### Conditionals
```prose
# Functional
if **has security issues**:
session "Fix security"
elif **has performance issues**:
session "Optimize"
else:
session "Approve"
```
```prose
# Nights
should **has security issues**:
tale "Fix security"
or should **has performance issues**:
tale "Optimize"
otherwise:
tale "Approve"
```
### Reusable Blocks (Frame Stories)
```prose
# Functional
block review(topic):
session "Research {topic}"
session "Analyze {topic}"
do review("quantum computing")
```
```prose
# Nights
frame review(topic):
tale "Research {topic}"
tale "Analyze {topic}"
tell review("quantum computing")
```
### Fixed Iteration
```prose
# Functional
repeat 1001:
session "Tell a story"
```
```prose
# Nights
1001 nights:
tale "Tell a story"
```
### Immutable Binding
```prose
# Functional
const config = { model: "opus", retries: 3 }
```
```prose
# Nights
oath config = { spirit: "opus", persist: 3 }
```
---
## The Case For Arabian Nights
1. **Frame narrative is recursion.** Stories within stories maps perfectly to nested program calls.
2. **Djinn/wish/gift.** The agent/input/output mapping is extremely clean.
3. **Rich tradition.** One Thousand and One Nights is globally known.
4. **Bazaar for parallel.** Many merchants, many stalls, all active at once—vivid metaphor.
5. **Oath for const.** An unbreakable vow is a perfect metaphor for immutability.
6. **"1001 nights"** as a loop count is delightful.
## The Case Against Arabian Nights
1. **Cultural sensitivity.** Must be handled respectfully, avoiding Orientalist tropes.
2. **"Djinn" pronunciation.** Users unfamiliar may be uncertain (jinn? djinn? genie?).
3. **Some mappings feel forced.** "Bazaar" for parallel is vivid but not obvious.
4. **"Should misfortune strike"** is long for `catch`.
---
## Key Arabian Nights Concepts
| Term | Meaning | Used for |
|------|---------|----------|
| Scheherazade | The narrator who tells tales to survive | (the program author) |
| Djinn | Supernatural spirit, bound to serve | `agent` → `djinn` |
| Frame story | A story that contains other stories | `block` → `frame` |
| Wish | What is asked of the djinn | `input` → `wish` |
| Oath | Unbreakable promise | `const` → `oath` |
| Bazaar | Marketplace, many vendors | `parallel` → `bazaar` |
---
## Alternatives Considered
### For `djinn` (agent)
| Keyword | Rejected because |
|---------|------------------|
| `genie` | Disney connotation, less literary |
| `spirit` | Used for `model` |
| `ifrit` | Too specific (a type of djinn) |
| `narrator` | Too meta, Scheherazade is the user |
### For `tale` (session)
| Keyword | Rejected because |
|---------|------------------|
| `story` | Good but `tale` feels more literary |
| `night` | Reserved for `repeat N nights` |
| `chapter` | More Western/novelistic |
### For `bazaar` (parallel)
| Keyword | Rejected because |
|---------|------------------|
| `caravan` | Sequential connotation (one after another) |
| `chorus` | Greek, wrong tradition |
| `souk` | Less widely known |
### For `scroll` (context)
| Keyword | Rejected because |
|---------|------------------|
| `letter` | Too small/personal |
| `tome` | Too large |
| `message` | Too plain |
---
## Verdict
Preserved for benchmarking. The Arabian Nights register offers a storytelling frame that maps naturally to recursive, nested programs. The djinn/wish/gift trio is particularly elegant.
Best suited for:
- Programs with deep nesting (stories within stories)
- Workflows that feel like granting wishes
- Users who enjoy narrative framing
The `frame` keyword for reusable blocks is especially apt—Scheherazade's frame story containing a thousand tales.

# OpenProse Borges Register
> **This is a skin layer.** It requires `prose.md` to be loaded first. All execution semantics, state management, and VM behavior are defined there. This file only provides keyword translations.
An alternative register for OpenProse that draws from the works of Jorge Luis Borges. Where the functional register is utilitarian and the folk register is whimsical, the Borges register is scholarly and metaphysical—everything feels like a citation from a fictional encyclopedia.
## How to Use

## The Case For Borges
1. **Metaphysical resonance.** AI sessions dreaming subagents into existence mirrors "The Circular Ruins."
2. **Scholarly tone.** `axiom`/`theorem` frame programs as logical derivations.
3. **Memorable metaphors.** The zahir you cannot change. The labyrinth you cannot escape. The library you retrieve from.
4. **Thematic coherence.** Borges wrote about infinity, recursion, and branching time—all core to computation.
5. **Literary prestige.** Borges is widely read; references land for many users.
## The Case Against Borges
1. **Requires familiarity.** "Zahir" and "Funes" are obscure to those who haven't read Borges.
2. **Potentially pretentious.** May feel like showing off rather than communicating.
3. **Translation overhead.** Users must map `labyrinth` → `loop` mentally.
4. **Cultural specificity.** Less universal than folk/fairy tale tropes.

## Key Borges References
For those unfamiliar with the source material:
| Work | Concept Used | Summary |
|------|--------------|---------|
| "The Circular Ruins" | `dreamer`, `dream` | A man dreams another man into existence, only to discover he himself is being dreamed |
| "The Garden of Forking Paths" | `forking`, `bifurcation`, `branch` | A labyrinth that is a book; time forks perpetually into diverging futures |
| "The Library of Babel" | `retrieve` | An infinite library containing every possible book |
| "Funes the Memorious" | `memory` | A man with perfect memory who cannot forget anything |
| "The Zahir" | `zahir` | An object that, once seen, cannot be forgotten or ignored |
| "The Aleph" | (not used) | A point in space containing all other points |
| "Tlön, Uqbar, Orbis Tertius" | (not used) | A fictional world that gradually becomes real |
---
## Alternatives Considered
### For `dreamer` (agent)
| Keyword | Rejected because |
|---------|------------------|
| `author` | Used for `model` instead |
| `scribe` | Too passive, just records |
| `librarian` | More curator than creator |
### For `labyrinth` (loop)
| Keyword | Rejected because |
|---------|------------------|
| `recursion` | Too technical |
| `eternal return` | Too long |
| `ouroboros` | Wrong mythology |
### For `zahir` (const)
| Keyword | Rejected because |
|---------|------------------|
| `aleph` | The Aleph is about totality, not immutability |
| `fixed` | Too plain |
| `eternal` | Overused |
### For `memory` (context)
| Keyword | Rejected because |
|---------|------------------|
| `funes` | Too obscure as standalone keyword |
| `recall` | Sounds like a function call |
| `archive` | More Library of Babel than Funes |
---
## Verdict
Preserved for benchmarking against the functional and folk registers. The Borges register offers a distinctly intellectual/metaphysical flavor that may resonate with users who appreciate literary computing.
Potential benchmarking questions:
1. **Learnability** — Is `labyrinth` intuitive for loops?
2. **Memorability** — Does `zahir` stick better than `const`?
3. **Comprehension** — Do users understand `dreamer`/`dream` immediately?
4. **Preference** — Which register do users find most pleasant?
5. **Error rates** — Does the metaphorical mapping cause mistakes?

## The Case For Folk
1. **"OpenProse" is literary.** Prose is a literary form—why not lean in?
2. **Fourth wall is theatrical.** `**...**` already uses theatre terminology.
3. **Signals difference.** Literary terms say "this is not your typical DSL."
4. **Internally consistent.** Everything draws from folklore/theatre/narrative.
5. **Memorable.** `sprite`, `scene`, `crossroads` stick in the mind.
6. **Model names already fit.** `sonnet`, `opus`, `haiku` are poetic forms.
## The Case Against Folk
1. **Cultural knowledge required.** Not everyone knows folklore tropes.
2. **Harder to Google.** "OpenProse summon" vs "OpenProse import."
3. **May feel precious.** Some users want utilitarian tools.
4. **Translation overhead.** Mental mapping to familiar concepts.

## Alternatives Considered
### For `sprite` (ephemeral agent)
| Keyword | Origin | Rejected because |
|---------|--------|------------------|
| `spark` | English | Good but less folklore |
| `wisp` | English | Too insubstantial |
| `herald` | English | More messenger than worker |
| `courier` | French | Good functional alternative, not literary |
| `envoy` | French | Formal, diplomatic |
### For `shade` (persistent agent, if implemented)
| Keyword | Origin | Rejected because |
|---------|--------|------------------|
| `daemon` | Greek/Unix | Unix "always running" connotation |
| `oracle` | Greek | Too "read-only" feeling |
| `spirit` | Latin | Too close to `sprite` |
| `specter` | Latin | Negative/spooky connotation |
| `genius` | Roman | Overloaded (smart person) |
### For `ensemble` (parallel)
| Keyword | Origin | Rejected because |
|---------|--------|------------------|
| `chorus` | Greek | Everyone speaks same thing, not different |
| `troupe` | French | Good alternative, slightly less clear |
| `company` | Theatre | Overloaded (business) |
### For `crossroads` (choice)
| Keyword | Origin | Rejected because |
|---------|--------|------------------|
| `fork` | Path | Too technical (git fork) |
| `branch` | Tree | Also too technical |
| `divergence` | Latin | Too abstract |
---
## Verdict
Preserved for benchmarking against the functional register. The functional register remains the primary path, but folk provides an interesting data point for:
1. **Learnability** — Which is easier for newcomers?
2. **Memorability** — Which sticks better?
3. **Error rates** — Which leads to fewer mistakes?
4. **Preference** — Which do users actually prefer?
A future experiment could present both registers and measure outcomes.

# OpenProse Homeric Register
> **This is a skin layer.** It requires `prose.md` to be loaded first. All execution semantics, state management, and VM behavior are defined there. This file only provides keyword translations.
An alternative register for OpenProse that draws from Greek epic poetry—the Iliad, the Odyssey, and the heroic tradition. Programs become quests. Agents become heroes. Outputs become glory won.
## How to Use
1. Load `prose.md` first (execution semantics)
2. Load this file (keyword translations)
3. When parsing `.prose` files, accept Homeric keywords as aliases for functional keywords
4. All execution behavior remains identical—only surface syntax changes
> **Design constraint:** Still aims to be "structured but self-evident" per the language tenets—just self-evident through an epic lens.
---
## Complete Translation Map
### Core Constructs
| Functional | Homeric | Reference |
|------------|---------|-----------|
| `agent` | `hero` | The one who acts, who strives |
| `session` | `trial` | Each task is a labor, a test |
| `parallel` | `host` | An army moving as one |
| `block` | `book` | A division of the epic |
### Composition & Binding
| Functional | Homeric | Reference |
|------------|---------|-----------|

| `output` | `glory` | Kleos — the glory won, what endures |
| `let` | `decree` | Fate declared, spoken into being |
| `const` | `fate` | Moira — unchangeable destiny |
| `context` | `tidings` | News carried by herald or messenger |
### Control Flow
| Functional | Homeric | Reference |
|------------|---------|-----------|
| `repeat N` | `N labors` | The labors of Heracles |
| `for...in` | `for each...among` | Among the host |
| `loop` | `ordeal` | Repeated trial, suffering that continues |

## Side-by-Side Comparison
### Simple Program
```prose
# Functional
use "@alice/research" as research
input topic: "What to investigate"
agent helper:
model: sonnet
let findings = session: helper
prompt: "Research {topic}"
output summary = session "Summarize"
context: findings
```
```prose
# Homeric
invoke "@alice/research" as research
omen topic: "What to investigate"
hero helper:
muse: sonnet
decree findings = trial: helper
charge: "Research {topic}"
glory summary = trial "Summarize"
tidings: findings
```
### Parallel Execution
```prose
# Functional
parallel:
security = session "Check security"
perf = session "Check performance"
style = session "Check style"
session "Synthesize review"
context: { security, perf, style }
```
```prose
# Homeric
host:
security = trial "Check security"
perf = trial "Check performance"
style = trial "Check style"
trial "Synthesize review"
tidings: { security, perf, style }
```
### Loop with Condition
```prose
# Functional
loop until **the code is bug-free** (max: 5):
session "Find and fix bugs"
```
```prose
# Homeric
ordeal until **the code is bug-free** (max: 5):
trial "Find and fix bugs"
```
### Error Handling

# Functional
try:
session "Risky operation"
catch as err:
session "Handle error"
context: err
finally:
session "Cleanup"
```
```prose
# Homeric
venture:
trial "Risky operation"
should ruin come as err:
trial "Handle error"
tidings: err
in the end:
trial "Cleanup"
```
### Choice Block
```prose
# Functional
choice **the severity level**:
option "Critical":
session "Escalate immediately"
option "Minor":
session "Log for later"
```
```prose
# Homeric
crossroads **the severity level**:
path "Critical":
trial "Escalate immediately"
path "Minor":
trial "Log for later"
```
### Conditionals
```prose
# Functional
if **has security issues**:
session "Fix security"
elif **has performance issues**:
session "Optimize"
else:
session "Approve"
```
```prose
# Homeric
should **has security issues**:
trial "Fix security"
or should **has performance issues**:
trial "Optimize"
otherwise:
trial "Approve"
```
### Reusable Blocks

session "Research {topic}"
session "Analyze {topic}"
do review("quantum computing")
```
```prose
# Homeric
book review(topic):
trial "Research {topic}"
trial "Analyze {topic}"
do review("quantum computing")
```
### Fixed Iteration
```prose
# Functional
repeat 12:
session "Complete task"
```
```prose
# Homeric
12 labors:
trial "Complete task"

```
```prose
# Homeric
fate config = { muse: "opus", persist: 3 }
```
---
## The Case For Homeric
1. **Universal recognition.** Greek epics are foundational to Western literature.
2. **Heroic framing.** Transforms mundane tasks into glorious trials.
3. **Natural fit.** Heroes face trials, receive tidings, win glory—maps cleanly to agent/session/output.
4. **Gravitas.** When you want programs to feel epic and consequential.
5. **Fate vs decree.** `const` as `fate` (unchangeable) vs `let` as `decree` (declared but mutable) is intuitive.
## The Case Against Homeric
1. **Grandiosity mismatch.** "12 labors" for a simple loop may feel overblown.
2. **Western-centric.** Greek epic tradition is culturally specific.
3. **Limited vocabulary.** Fewer distinctive terms than Borges or folk.
4. **Potentially silly.** Heroic language for mundane tasks risks bathos.
---
## Key Homeric Concepts
| Term | Meaning | Used for |
|------|---------|----------|
| Kleos | Glory, fame that outlives you | `output` → `glory` |
| Moira | Fate, one's allotted portion | `const` → `fate` |
| Até | Divine ruin, blindness sent by gods | `catch` → `should ruin come` |
| Nostos | The return journey | (not used, but could be `finally`) |
| Xenia | Guest-friendship, hospitality | (not used) |
| Muse | Divine inspiration | `model` → `muse` |
---
## Alternatives Considered
### For `hero` (agent)
| Keyword | Rejected because |
|---------|------------------|
| `champion` | More medieval than Homeric |
| `warrior` | Too martial, not all tasks are battles |
| `wanderer` | Too passive |
### For `trial` (session)
| Keyword | Rejected because |
|---------|------------------|
| `labor` | Good but reserved for `repeat N labors` |
| `quest` | More medieval/RPG |
| `task` | Too plain |
### For `host` (parallel)
| Keyword | Rejected because |
|---------|------------------|
| `army` | Too specifically martial |
| `fleet` | Only works for naval metaphors |
| `phalanx` | Too technical |
---
## Verdict
Preserved for benchmarking. The Homeric register offers gravitas and heroic framing. Best suited for:
- Programs that feel like epic undertakings
- Users who enjoy classical references
- Contexts where "glory" as output feels appropriate
May cause unintentional bathos when applied to mundane tasks.

# OpenProse Kafka Register
> **This is a skin layer.** It requires `prose.md` to be loaded first. All execution semantics, state management, and VM behavior are defined there. This file only provides keyword translations.
An alternative register for OpenProse that draws from the works of Franz Kafka—The Trial, The Castle, "In the Penal Colony." Programs become proceedings. Agents become clerks. Everything is a process, and nobody quite knows the rules.
## How to Use
1. Load `prose.md` first (execution semantics)
2. Load this file (keyword translations)
3. When parsing `.prose` files, accept Kafka keywords as aliases for functional keywords
4. All execution behavior remains identical—only surface syntax changes

## The Case For Kafka
1. **Darkly comic.** Programs-as-bureaucracy is funny and relatable.
2. **Surprisingly apt.** Software often *is* an inscrutable apparatus.
3. **Clean mappings.** Petition/verdict, file/dossier, clerk/proceeding all work well.
4. **Appeal as loop.** The endless appeal process is a perfect metaphor for retry logic.
5. **Cultural resonance.** "Kafkaesque" is a widely understood adjective.
6. **Self-aware.** Using Kafka for a programming language acknowledges the absurdity.
## The Case Against Kafka
1. **Bleak tone.** Not everyone wants their programs to feel like The Trial.
2. **Verbose keywords.** "In the event that" and "should it be denied" are long.
3. **Anxiety-inducing.** May not be fun for users who find bureaucracy stressful.
4. **Irony may not land.** Some users might take it literally and find it off-putting.
---
## Key Kafka Concepts
| Term | Meaning | Used for |
|------|---------|----------|
| The apparatus | The inscrutable system | The VM itself |
| K. | The protagonist, never fully named | The user |
| The Trial | Process without clear rules | Program execution |
| The Castle | Unreachable authority | Higher-level systems |
| Clerk | Functionary who processes | `agent` → `clerk` |
| Proceeding | Official action | `session` → `proceeding` |
| Dossier | Accumulated file | `context` → `dossier` |
---
## Alternatives Considered
### For `clerk` (agent)
| Keyword | Rejected because |
|---------|------------------|
| `official` | Too generic |
| `functionary` | Hard to spell |
| `bureaucrat` | Too pejorative |
| `advocate` | Too positive/helpful |
### For `proceeding` (session)
| Keyword | Rejected because |
|---------|------------------|
| `case` | Overloaded (switch case) |
| `hearing` | Reserved for `repeat N hearings` |
| `trial` | Used in Homeric register |
| `process` | Too technical |
### For `departments` (parallel)
| Keyword | Rejected because |
|---------|------------------|
| `bureaus` | Good alternative, slightly less clear |
| `offices` | Too mundane |
| `ministries` | More Orwellian than Kafkaesque |
### For `appeal` (loop)
| Keyword | Rejected because |
|---------|------------------|
| `recourse` | Too legal-technical |
| `petition` | Used for `input` |
| `process` | Too generic |
---
## Verdict
Preserved for benchmarking. The Kafka register offers a darkly comic, self-aware framing that acknowledges the bureaucratic nature of software systems. The irony is the point.
Best suited for:
- Users with a sense of humor about software complexity
- Programs that genuinely feel like navigating bureaucracy
- Contexts where acknowledging absurdity is welcome
Not recommended for:
- Users who find bureaucratic metaphors stressful
- Contexts requiring earnest, positive framing
- Documentation that needs to feel approachable
---
## Closing Note
> "Someone must have slandered Josef K., for one morning, without having done anything wrong, he was arrested."
> — *The Trial*
In the Kafka register, your program is Josef K. The apparatus will process it. Whether it succeeds or fails, no one can say for certain. But the proceedings will continue.

# The Captain's Chair
#
# A project management orchestration pattern where a prime agent dispatches
# specialized subagents for all coding, validation, and task execution.
# The captain never writes code directly—only coordinates, validates, and
# maintains strategic oversight.
#
# Key principles:
# - Context isolation: Subagents receive targeted context, not everything
# - Parallel execution: Multiple subagents work concurrently where possible
# - Critic agents: Continuous review of plans and outputs
# - Checkpoint validation: User approval at key decision points

# Skill Security Scanner v2
#
# Scans installed AI coding assistant skills/plugins for security vulnerabilities.
# Supports Claude Code, AMP, and other tools that use the SKILL.md format.
#
# KEY IMPROVEMENTS (v2):
# - Progressive disclosure: quick triage before deep scan (saves cost on clean skills)
# - Model tiering: Sonnet for checklist work, Opus for hard analysis
# - Parallel scanners: Independent analyses run concurrently
# - Persistent memory: Track scan history across runs (with sqlite+ backend)
# - Graceful degradation: Individual scanner failures don't break the whole scan
# - Customizable: scan mode, focus areas, specific skills
#
# USAGE:
# prose run 38-skill-scan.prose # Standard scan
# prose run 38-skill-scan.prose mode:"quick" # Fast triage only
# prose run 38-skill-scan.prose mode:"deep" # Full analysis, all skills
# prose run 38-skill-scan.prose focus:"prompt-injection" # Focus on specific category
# prose run 38-skill-scan.prose --backend sqlite+ # Enable persistent history
input mode: "Scan mode: 'quick' (triage only), 'standard' (triage + deep on concerns), 'deep' (full analysis)"

# - Persistent architect: Maintains master plan and synthesizes learnings
# - User checkpoint: Get plan approval BEFORE executing the pipeline

#
# This extends the basic UX test with a comprehensive error handling pipeline:
# - If blocking errors are detected, investigate using logs, database, and code
# - Verify diagnosis through synthesis loop
# - Triage: quick fix vs. bigger change requiring CEO oversight
# - Quick fixes: engineer implements, deploys, tests, iterates
# - Bigger changes: build plan, parallel engineers, review, deploy, smoke test
#
# Key patterns demonstrated:
# - Mid-program `input` for user checkpoints
# - Persistent agents with `resume:` for accumulated context
# - Parallel investigation with multiple angles
# - `choice` blocks for triage decisions
# - `retry` with backoff for flaky operations
# - Recursive self-healing (if fix fails, re-test)

# BACKEND: Run with sqlite+ or postgres for incremental processing across runs
# prose run 48-habit-miner.prose --backend sqlite+
#
# KEY VM FEATURES USED:
# - persist: true on miner — remembers patterns across runs, watches them mature
# - resume: — incremental processing, only analyzes new logs since last run
# - recursive blocks — handles arbitrarily large log corpora
# - reference-based context — agents read from storage, not everything in memory

## The Architect By Simulation Pattern
The architect-by-simulation pattern is for designing systems by "implementing" them through reasoning. Instead of writing code, each phase produces specification documents that the next phase builds upon.
**Key principles:**
1. **Thinking/deduction framework**: "Implement" means reasoning through design decisions
2. **Serial pipeline with handoffs**: Each phase reads previous phase's output
3. **Persistent architect**: Maintains master plan and synthesizes learnings
4. **User checkpoint**: Get plan approval BEFORE executing the pipeline
5. **Simulation as implementation**: The spec IS the deliverable
```prose
# The core pattern
agent architect:
model: opus
persist: true
prompt: "Design by simulating implementation"
# Create master plan with phases
let plan = session: architect
prompt: "Break feature into design phases"
# User reviews the plan BEFORE the pipeline runs
input user_approval: "User reviews plan and approves"
# Execute phases serially with handoffs
for phase_name, index in phases:
let handoff = session: phase-executor
prompt: "Execute phase {index}"
context: previous_handoffs
# Architect synthesizes after each phase
resume: architect
prompt: "Synthesize learnings from phase {index}"
context: handoff
# Synthesize all handoffs into final spec
output spec = session: architect
prompt: "Synthesize all handoffs into final spec"
```
See example 39 for the full implementation.
## The Captain's Chair Pattern
The captain's chair is an orchestration paradigm where a coordinating agent (the "captain") dispatches specialized subagents for all execution. The captain never writes code directly—only plans, coordinates, and validates.
**Key principles:**
1. **Context isolation**: Subagents receive targeted context, not everything
2. **Parallel execution**: Multiple subagents work concurrently where possible
3. **Continuous criticism**: Critic agents review plans and outputs mid-stream
4. **80/20 planning**: 80% effort on planning, 20% on execution oversight
5. **Checkpoint validation**: User approval at key decision points
```prose
# The core pattern
agent captain:
model: opus
prompt: "Coordinate but never execute directly"
agent executor:
model: sonnet
prompt: "Execute assigned tasks precisely"
agent critic:
model: sonnet
prompt: "Review work and find issues"
# Captain plans
let plan = session: captain
prompt: "Break down this task"
# Parallel execution with criticism
parallel:
work = session: executor
context: plan
review = session: critic
context: plan
# Captain validates
output result = session: captain
prompt: "Validate and integrate"
context: { work, review }
```
See examples 29-31 for full implementations.
## The Recursive Language Model Pattern
Recursive Language Models (RLMs) are a paradigm for handling inputs far beyond context limits. The key insight: treat the prompt as an external environment that the LLM can symbolically interact with, chunk, and recursively process.
**Why RLMs matter:**
- Base LLMs degrade rapidly on long contexts ("context rot")
- RLMs maintain performance on inputs 2 orders of magnitude beyond context limits
- On quadratic-complexity tasks, base models get <0.1% while RLMs achieve 58%
**Key patterns:**
1. **Self-refinement**: Recursive improvement until quality threshold
2. **Divide-and-conquer**: Chunk, process, aggregate recursively
3. **Filter-then-recurse**: Cheap filtering before expensive deep dives
4. **Pairwise aggregation**: Handle O(n²) tasks through batch decomposition
```prose
# The core RLM pattern: recursive block with scope isolation
block process(data, depth):
# Base case
if **data is small** or depth <= 0:
output session "Process directly"
context: data
# Recursive case: chunk and fan out
let chunks = session "Split into logical chunks"
context: data
parallel for chunk in chunks:
do process(chunk, depth - 1) # Recursive call
# Aggregate results (fan in)
output session "Synthesize partial results"
```
**OpenProse advantages for RLMs:**
- **Scope isolation**: Each recursive call gets its own `execution_id`, preventing variable collisions
- **Parallel fan-out**: `parallel for` enables concurrent processing at each recursion level
- **State persistence**: SQLite/PostgreSQL backends track the full call tree
- **Natural aggregation**: Pipelines (`| reduce`) and explicit context passing
See examples 40-43 for full implementations.

# OpenProse Antipatterns
This document catalogs patterns that lead to brittle, expensive, slow, or unmaintainable programs. Each antipattern includes recognition criteria and remediation guidance.
---
## Structural Antipatterns
#### god-session
A single session that tries to do everything. God sessions are hard to debug, impossible to parallelize, and produce inconsistent results.
```prose
# Bad: One session doing too much
session """
Read all the code in the repository.
Identify security vulnerabilities.
Find performance bottlenecks.
Check for style violations.
Generate a comprehensive report.
Suggest fixes for each issue.
Prioritize by severity.
Create a remediation plan.
"""
```
**Why it's bad**: The session has no clear completion criteria. It mixes concerns that could be parallelized. Failure anywhere fails everything.
**Fix**: Decompose into focused sessions:
```prose
# Good: Focused sessions
parallel:
security = session "Identify security vulnerabilities"
perf = session "Find performance bottlenecks"
style = session "Check for style violations"
session "Synthesize findings and prioritize by severity"
context: { security, perf, style }
session "Create remediation plan"
```
#### sequential-when-parallel
Running independent operations sequentially when they could run concurrently. Wastes wall-clock time.
```prose
# Bad: Sequential independent work
let market = session "Research market"
let tech = session "Research technology"
let competition = session "Research competition"
session "Synthesize"
context: [market, tech, competition]
```
**Why it's bad**: Total time is sum of all research times. Each session waits for the previous one unnecessarily.
**Fix**: Parallelize independent work:
```prose
# Good: Parallel independent work
parallel:
market = session "Research market"
tech = session "Research technology"
competition = session "Research competition"
session "Synthesize"
context: { market, tech, competition }
```
#### spaghetti-context
Context passed haphazardly without clear data flow. Makes programs hard to understand and modify.
```prose
# Bad: Unclear what context is actually used
let a = session "Step A"
let b = session "Step B"
context: a
let c = session "Step C"
context: [a, b]
let d = session "Step D"
context: [a, b, c]
let e = session "Step E"
context: [a, c, d] # Why not b?
let f = session "Step F"
context: [a, b, c, d, e] # Everything?
```
**Why it's bad**: Unclear which sessions depend on which outputs. Hard to parallelize or refactor.
**Fix**: Minimize context to actual dependencies:
```prose
# Good: Clear, minimal dependencies
let research = session "Research"
let analysis = session "Analyze"
context: research
let recommendations = session "Recommend"
context: analysis # Only needs analysis, not research
let report = session "Report"
context: recommendations
```
#### parallel-then-synthesize
Spawning parallel agents for related analytical work, then synthesizing, when a single focused agent could do the entire job more efficiently.
```prose
# Antipattern: Parallel investigation + synthesis
parallel:
code = session "Analyze code path"
logs = session "Analyze logs"
context = session "Analyze execution context"
synthesis = session "Synthesize all findings"
context: { code, logs, context }
# 4 LLM calls, coordination overhead, fragmented context
```
**Why it's bad**: For related analysis that feeds into one conclusion, the coordination overhead and context fragmentation often outweigh parallelism benefits. Each parallel agent sees only part of the picture.
**Fix**: Use a single focused agent with multi-step instructions:
```prose
# Good: Single comprehensive investigator
diagnosis = session "Investigate the error"
prompt: """Analyze comprehensively:
1. Check the code path that produced the error
2. Examine logs for timing and state
3. Review execution context
Synthesize into a unified diagnosis."""
# 1 LLM call, full context, no coordination
```
**When parallel IS right**: When analyses are truly independent (security vs performance), when you want diverse perspectives that shouldn't influence each other, or when the work is so large it genuinely benefits from division.
#### copy-paste-workflows
Duplicating session sequences instead of using blocks. Leads to inconsistent changes and maintenance burden.
```prose
# Bad: Duplicated workflow
session "Security review of module A"
session "Performance review of module A"
session "Synthesize reviews of module A"
session "Security review of module B"
session "Performance review of module B"
session "Synthesize reviews of module B"
session "Security review of module C"
session "Performance review of module C"
session "Synthesize reviews of module C"
```
**Why it's bad**: If the workflow needs to change, you must change it everywhere. Easy to miss one.
**Fix**: Extract into a block:
```prose
# Good: Reusable block
block review-module(module):
parallel:
sec = session "Security review of {module}"
perf = session "Performance review of {module}"
session "Synthesize reviews of {module}"
context: { sec, perf }
do review-module("module A")
do review-module("module B")
do review-module("module C")
```
---
## Robustness Antipatterns
#### unbounded-loop
A loop without max iterations. Can run forever if the condition is never satisfied.
```prose
# Bad: No escape hatch
loop until **the code is perfect**:
session "Improve the code"
```
**Why it's bad**: "Perfect" may never be achieved. The program could run indefinitely, consuming resources.
**Fix**: Always specify `max:`:
```prose
# Good: Bounded iteration
loop until **the code is perfect** (max: 10):
session "Improve the code"
```
#### optimistic-execution
Assuming everything will succeed. No error handling for operations that can fail.
```prose
# Bad: No error handling
session "Call external API"
session "Process API response"
session "Store results in database"
session "Send notification"
```
**Why it's bad**: If the API fails, subsequent sessions receive no valid input. Silent corruption.
**Fix**: Handle failures explicitly:
```prose
# Good: Error handling
try:
let response = session "Call external API"
retry: 3
backoff: "exponential"
session "Process API response"
context: response
catch as err:
session "Handle API failure gracefully"
context: err
```
#### ignored-errors
Using `on-fail: "ignore"` when failures actually matter. Masks problems that should surface.
```prose
# Bad: Ignoring failures that matter
parallel (on-fail: "ignore"):
session "Charge customer credit card"
session "Ship the product"
session "Send confirmation email"
session "Order complete!" # But was it really?
```
**Why it's bad**: The order might be marked complete even if payment failed.
**Fix**: Use appropriate failure policy:
```prose
# Good: Fail-fast for critical operations
parallel: # Default: fail-fast
payment = session "Charge customer credit card"
inventory = session "Reserve inventory"
# Only ship if both succeeded
session "Ship the product"
context: { payment, inventory }
# Email can fail without blocking
try:
session "Send confirmation email"
catch:
session "Queue email for retry"
```
#### vague-discretion
Discretion conditions that are ambiguous or unmeasurable.
```prose
# Bad: What does "good enough" mean?
loop until **the output is good enough**:
session "Improve output"
# Bad: Highly subjective
if **the user will be happy**:
session "Ship it"
```
**Why it's bad**: The VM has no clear criteria for evaluation. Results are unpredictable.
**Fix**: Provide concrete, evaluatable criteria:
```prose
# Good: Specific criteria
loop until **all tests pass and code coverage exceeds 80%** (max: 10):
session "Improve test coverage"
# Good: Observable conditions
if **the response contains valid JSON with all required fields**:
session "Process the response"
```
#### catch-and-swallow
Catching errors without meaningful handling. Hides problems without solving them.
```prose
# Bad: Silent swallow
try:
session "Critical operation"
catch:
# Nothing here - error disappears
```
**Why it's bad**: Errors vanish. No recovery, no logging, no visibility.
**Fix**: Handle errors meaningfully:
```prose
# Good: Meaningful handling
try:
session "Critical operation"
catch as err:
session "Log error for investigation"
context: err
session "Execute fallback procedure"
# Or rethrow if unrecoverable:
throw
```
---
## Cost Antipatterns
#### opus-for-everything
Using the most powerful (expensive) model for all tasks, including trivial ones.
```prose
# Bad: Opus for simple classification
agent classifier:
model: opus
prompt: "Categorize items as: spam, not-spam"
# Expensive for a binary classification
for email in emails:
session: classifier
prompt: "Classify: {email}"
```
**Why it's bad**: Opus costs significantly more than haiku. Simple tasks don't benefit from advanced reasoning.
**Fix**: Match model to task complexity:
```prose
# Good: Haiku for simple tasks
agent classifier:
model: haiku
prompt: "Categorize items as: spam, not-spam"
```
#### context-bloat
Passing excessive context that the session doesn't need.
```prose
# Bad: Passing everything
let full_codebase = session "Read entire codebase"
let all_docs = session "Read all documentation"
let history = session "Get full git history"
session "Fix the typo in the README"
context: [full_codebase, all_docs, history] # Massive overkill
```
**Why it's bad**: Large contexts slow processing, increase costs, and can confuse the model with irrelevant information.
**Fix**: Pass minimal relevant context:
```prose
# Good: Minimal context
let readme = session "Read the README file"
session "Fix the typo in the README"
context: readme
```
#### unnecessary-iteration
Looping when a single session would suffice.
```prose
# Bad: Loop for what could be one call
let items = ["apple", "banana", "cherry"]
for item in items:
session "Describe {item}"
```
**Why it's bad**: Three sessions when one could handle all items. Session overhead multiplied.
**Fix**: Batch when possible:
```prose
# Good: Batch processing
let items = ["apple", "banana", "cherry"]
session "Describe each of these items: {items}"
```
#### redundant-computation
Computing the same thing multiple times.
```prose
# Bad: Redundant research
session "Research AI safety for security review"
session "Research AI safety for ethics review"
session "Research AI safety for compliance review"
```
**Why it's bad**: Same research done three times with slightly different framing.
**Fix**: Compute once, use many times:
```prose
# Good: Compute once
let research = session "Comprehensive research on AI safety"
parallel:
session "Security review"
context: research
session "Ethics review"
context: research
session "Compliance review"
context: research
```
---
## Performance Antipatterns
#### eager-over-computation
Computing everything upfront when only some results might be needed.
```prose
# Bad: Compute all branches even if only one is needed
parallel:
simple_analysis = session "Simple analysis"
model: haiku
detailed_analysis = session "Detailed analysis"
model: sonnet
deep_analysis = session "Deep analysis"
model: opus
# Then only use one based on some criterion
choice **appropriate depth**:
option "Simple":
session "Use simple"
context: simple_analysis
option "Detailed":
session "Use detailed"
context: detailed_analysis
option "Deep":
session "Use deep"
context: deep_analysis
```
**Why it's bad**: All three analyses run even though only one is used.
**Fix**: Compute lazily:
```prose
# Good: Only compute what's needed
let initial = session "Initial assessment"
model: haiku
choice **appropriate depth based on initial assessment**:
option "Simple":
session "Simple analysis"
model: haiku
option "Detailed":
session "Detailed analysis"
model: sonnet
option "Deep":
session "Deep analysis"
model: opus
```
#### over-parallelization
Parallelizing so aggressively that overhead dominates or resources are exhausted.
```prose
# Bad: 100 parallel sessions
parallel for item in large_collection: # 100 items
session "Process {item}"
```
**Why it's bad**: May overwhelm the system. Coordination overhead can exceed parallelism benefits.
**Fix**: Batch or limit concurrency:
```prose
# Good: Process in batches
for batch in batches(large_collection, 10):
parallel for item in batch:
session "Process {item}"
```
#### premature-parallelization
Parallelizing tiny tasks where sequential would be simpler and fast enough.
```prose
# Bad: Parallel overkill for simple tasks
parallel:
a = session "Add 2 + 2"
b = session "Add 3 + 3"
c = session "Add 4 + 4"
```
**Why it's bad**: Coordination overhead exceeds task time. Sequential would be simpler and possibly faster.
**Fix**: Keep it simple:
```prose
# Good: Sequential for trivial tasks
session "Add 2+2, 3+3, and 4+4"
```
#### synchronous-fire-and-forget
Waiting for operations whose results you don't need.
```prose
# Bad: Waiting for logging
session "Do important work"
session "Log the result" # Don't need to wait for this
session "Continue with next important work"
```
**Why it's bad**: Main workflow blocked by non-critical operation.
**Fix**: Use appropriate patterns for fire-and-forget operations, or batch logging:
```prose
# Better: Batch non-critical work
session "Do important work"
session "Continue with next important work"
# ... more important work ...
# Log everything at the end or async
session "Log all operations"
```
---
## Maintainability Antipatterns
#### magic-strings
Hardcoded prompts repeated throughout the program.
```prose
# Bad: Same prompt in multiple places
session "You are a helpful assistant. Analyze this code for bugs."
# ... later ...
session "You are a helpful assistant. Analyze this code for bugs."
# ... even later ...
session "You are a helpful assistent. Analyze this code for bugs." # Typo!
```
**Why it's bad**: Inconsistency when updating. Typos go unnoticed.
**Fix**: Use agents:
```prose
# Good: Single source of truth
agent code-analyst:
model: sonnet
prompt: "You are a helpful assistant. Analyze code for bugs."
session: code-analyst
prompt: "Analyze the auth module"
session: code-analyst
prompt: "Analyze the payment module"
```
#### opaque-workflow
No structure or comments indicating what's happening.
```prose
# Bad: What is this doing?
let x = session "A"
let y = session "B"
context: x
parallel:
z = session "C"
context: y
w = session "D"
session "E"
context: [z, w]
```
**Why it's bad**: Impossible to understand, debug, or modify.
**Fix**: Use meaningful names and structure:
```prose
# Good: Clear intent
# Phase 1: Research
let research = session "Gather background information"
# Phase 2: Analysis
let analysis = session "Analyze research findings"
context: research
# Phase 3: Parallel evaluation
parallel:
technical_eval = session "Technical feasibility assessment"
context: analysis
business_eval = session "Business viability assessment"
context: analysis
# Phase 4: Synthesis
session "Create final recommendation"
context: { technical_eval, business_eval }
```
#### implicit-dependencies
Relying on conversation history rather than explicit context.
```prose
# Bad: Implicit state
session "Set the project name to Acme"
session "Set the deadline to Friday"
session "Now create a project plan" # Hopes previous info is remembered
```
**Why it's bad**: Relies on VM implementation details. Fragile across refactoring.
**Fix**: Explicit context:
```prose
# Good: Explicit state
let config = session "Define project: name=Acme, deadline=Friday"
session "Create a project plan"
context: config
```
#### mixed-concerns-agent
Agents with prompts that cover too many responsibilities.
```prose
# Bad: Jack of all trades
agent super-agent:
model: opus
prompt: """
You are an expert in:
- Security analysis
- Performance optimization
- Code review
- Documentation
- Testing
- DevOps
- Project management
- Customer communication
When asked, perform any of these tasks.
"""
```
**Why it's bad**: No focus means mediocre results across the board. Can't optimize model choice.
**Fix**: Specialized agents:
```prose
# Good: Focused expertise
agent security-expert:
model: sonnet
prompt: "You are a security analyst. Focus only on security concerns."
agent performance-expert:
model: sonnet
prompt: "You are a performance engineer. Focus only on optimization."
agent technical-writer:
model: haiku
prompt: "You write clear technical documentation."
```
---
## Logic Antipatterns
#### infinite-refinement
Loops that can never satisfy their exit condition.
```prose
# Bad: Perfection is impossible
loop until **the code has zero bugs**:
session "Find and fix bugs"
```
**Why it's bad**: Zero bugs is unachievable. Loop runs until max (if specified) or forever.
**Fix**: Use achievable conditions:
```prose
# Good: Achievable condition
loop until **all known bugs are fixed** (max: 20):
session "Find and fix the next bug"
# Or: Diminishing returns
loop until **no significant bugs found in last iteration** (max: 10):
session "Search for bugs"
```
#### assertion-as-action
Using conditions as actions—checking something without acting on the result.
```prose
# Bad: Check but don't use result
session "Check if the system is healthy"
session "Deploy to production" # Deploys regardless!
```
**Why it's bad**: The health check result isn't used. Deploy happens unconditionally.
**Fix**: Use conditional execution:
```prose
# Good: Act on the check
let health = session "Check if the system is healthy"
if **system is healthy**:
session "Deploy to production"
else:
session "Alert on-call and skip deployment"
context: health
```
#### false-parallelism
Putting sequential-dependent operations in a parallel block.
```prose
# Bad: These aren't independent!
parallel:
data = session "Fetch data"
processed = session "Process the data" # Needs data!
context: data
stored = session "Store processed data" # Needs processed!
context: processed
```
**Why it's bad**: Despite being in parallel, these must run sequentially due to dependencies.
**Fix**: Be honest about dependencies:
```prose
# Good: Sequential where needed
let data = session "Fetch data"
let processed = session "Process the data"
context: data
session "Store processed data"
context: processed
```
#### exception-as-flow-control
Using try/catch for expected conditions rather than exceptional errors.
```prose
# Bad: Exceptions for normal flow
try:
session "Find the optional config file"
catch:
session "Use default configuration"
```
**Why it's bad**: Missing config is expected, not exceptional. Obscures actual errors.
**Fix**: Use conditionals for expected cases:
```prose
# Good: Conditional for expected case
let config_exists = session "Check if config file exists"
if **config file exists**:
session "Load configuration from file"
else:
session "Use default configuration"
```
#### excessive-user-checkpoints
Prompting the user for decisions that have obvious or predictable answers.
```prose
# Antipattern: Asking the obvious
input "Blocking error detected. Investigate?" # Always yes
input "Diagnosis complete. Proceed to triage?" # Always yes
input "Tests pass. Deploy?" # Almost always yes
```
**Why it's bad**: Each checkpoint is a round-trip waiting for user input. If the answer is predictable 90% of the time, you're adding latency for no value.
**Fix**: Auto-proceed for obvious cases, only prompt when genuinely ambiguous:
```prose
# Good: Auto-proceed with escape hatches for edge cases
if observation.blocking_error:
# Auto-investigate (don't ask - of course we investigate errors)
let diagnosis = do investigate(...)
# Only ask if genuinely ambiguous
if diagnosis.confidence == "low":
input "Low confidence diagnosis. Proceed anyway?"
# Auto-deploy if tests pass (but log for audit)
if fix.tests_pass:
do deploy(...)
```
**When checkpoints ARE right**: Irreversible actions (production deployments to critical systems), expensive operations (long-running jobs), or genuine decision points where the user's preference isn't predictable.
#### fixed-observation-window
Waiting for a predetermined duration when the signal arrived early.
```prose
# Antipattern: Fixed window regardless of findings
loop 30 times (wait: 2s each): # Always 60 seconds
resume: observer
prompt: "Keep watching the stream"
# Runs all 30 iterations even if blocking error detected on iteration 1
```
**Why it's bad**: Wastes time when the answer is already known. If the observer detected a fatal error at +5 seconds, why wait another 55 seconds?
**Fix**: Use signal-driven exit conditions:
```prose
# Good: Exit on significant signal
loop until **blocking error OR completion** (max: 30):
resume: observer
prompt: "Watch the stream. Signal IMMEDIATELY on blocking errors."
# Exits as soon as something significant happens
```
Or use `early_exit` if your runtime supports it:
```prose
# Good: Explicit early exit
let observation = session: observer
prompt: "Monitor for errors. Signal immediately if found."
timeout: 120s
early_exit: **blocking_error detected**
```
---
## Security Antipatterns
#### unvalidated-input
Passing external input directly to sessions without validation.
```prose
# Bad: Direct injection
let user_input = external_source
session "Execute this command: {user_input}"
```
**Why it's bad**: User could inject malicious prompts or commands.
**Fix**: Validate and sanitize:
```prose
# Good: Validate first
let user_input = external_source
let validated = session "Validate this input is a safe search query"
context: user_input
if **input is valid and safe**:
session "Search for: {validated}"
else:
throw "Invalid input rejected"
```
#### overprivileged-agents
Agents with more permissions than they need.
```prose
# Bad: Full access for simple task
agent file-reader:
permissions:
read: ["**/*"]
write: ["**/*"]
bash: allow
network: allow
session: file-reader
prompt: "Read the README.md file"
```
**Why it's bad**: Task only needs to read one file but has full system access.
**Fix**: Least privilege:
```prose
# Good: Minimal permissions
agent file-reader:
permissions:
read: ["README.md"]
write: []
bash: deny
network: deny
```
---
## Summary
Antipatterns emerge from:
1. **Laziness**: Copy-paste instead of abstraction, implicit instead of explicit
2. **Over-engineering**: Parallelizing everything, using opus for all tasks
3. **Under-engineering**: No error handling, unbounded loops, vague conditions
4. **Unclear thinking**: God sessions, mixed concerns, spaghetti context
When reviewing OpenProse programs, ask:
- Can independent work be parallelized?
- Are loops bounded?
- Are errors handled?
- Is context minimal and explicit?
- Are models matched to task complexity?
- Are agents focused and reusable?
- Would a stranger understand this code?
Fix antipatterns early. They compound over time into unmaintainable systems.

# OpenProse Design Patterns
This document catalogs proven patterns for orchestrating AI agents effectively. Each pattern addresses specific concerns: robustness, cost efficiency, speed, maintainability, or self-improvement capability.
---
## Structural Patterns
#### parallel-independent-work
When tasks have no data dependencies, execute them concurrently. This maximizes throughput and minimizes wall-clock time.
```prose
# Good: Independent research runs in parallel
parallel:
market = session "Research market trends"
tech = session "Research technology landscape"
competition = session "Analyze competitor products"
session "Synthesize findings"
context: { market, tech, competition }
```
The synthesis session waits for all branches, but total time equals the longest branch rather than the sum of all branches.
#### fan-out-fan-in
For processing collections, fan out to parallel workers then collect results. Use `parallel for` instead of manual parallel branches.
```prose
let topics = ["AI safety", "interpretability", "alignment", "robustness"]
parallel for topic in topics:
session "Deep dive research on {topic}"
session "Create unified report from all research"
```
This scales naturally with collection size and keeps code DRY.
#### pipeline-composition
Chain transformations using pipe operators for readable data flow. Each stage has a single responsibility.
```prose
let candidates = session "Generate 10 startup ideas"
let result = candidates
| filter:
session "Is this idea technically feasible? yes/no"
context: item
| map:
session "Expand this idea into a one-page pitch"
context: item
| reduce(best, current):
session "Compare these two pitches, return the stronger one"
context: [best, current]
```
#### agent-specialization
Define agents with focused expertise. Specialized agents produce better results than generalist prompts.
```prose
agent security-reviewer:
model: sonnet
prompt: """
You are a security expert. Focus exclusively on:
- Authentication and authorization flaws
- Injection vulnerabilities
- Data exposure risks
Ignore style, performance, and other concerns.
"""
agent performance-reviewer:
model: sonnet
prompt: """
You are a performance engineer. Focus exclusively on:
- Algorithmic complexity
- Memory usage patterns
- I/O bottlenecks
Ignore security, style, and other concerns.
"""
```
#### reusable-blocks
Extract repeated workflows into parameterized blocks. Blocks are the functions of OpenProse.
```prose
block review-and-revise(artifact, criteria):
let feedback = session "Review {artifact} against {criteria}"
session "Revise {artifact} based on feedback"
context: feedback
# Reuse the pattern
do review-and-revise("the architecture doc", "clarity and completeness")
do review-and-revise("the API design", "consistency and usability")
do review-and-revise("the test plan", "coverage and edge cases")
```
---
## Robustness Patterns
#### bounded-iteration
Always constrain loops with `max:` to prevent runaway execution. Even well-crafted conditions can fail to terminate.
```prose
# Good: Explicit upper bound
loop until **all tests pass** (max: 20):
session "Identify and fix the next failing test"
# The program will terminate even if tests never fully pass
```
#### graceful-degradation
Use `on-fail: "continue"` when partial results are acceptable. Collect what you can rather than failing entirely.
```prose
parallel (on-fail: "continue"):
primary = session "Query primary data source"
backup = session "Query backup data source"
cache = session "Check local cache"
# Continue with whatever succeeded
session "Merge available data"
context: { primary, backup, cache }
```
#### retry-with-backoff
External services fail transiently. Retry with exponential backoff to handle rate limits and temporary outages.
```prose
session "Call external API"
retry: 5
backoff: "exponential"
```
For critical paths, combine retry with fallback:
```prose
try:
session "Call primary API"
retry: 3
backoff: "exponential"
catch:
session "Use fallback data source"
```
#### error-context-capture
Capture error context for intelligent recovery. The error variable provides information for diagnostic or remediation sessions.
```prose
try:
session "Deploy to production"
catch as err:
session "Analyze deployment failure and suggest fixes"
context: err
session "Attempt automatic remediation"
context: err
```
#### defensive-context
Validate assumptions before expensive operations. Cheap checks prevent wasted computation.
```prose
let prereqs = session "Check all prerequisites: API keys, permissions, dependencies"
if **prerequisites are not met**:
session "Report missing prerequisites and exit"
context: prereqs
throw "Prerequisites not satisfied"
# Expensive operations only run if prereqs pass
session "Execute main workflow"
```
---
## Cost Efficiency Patterns
#### model-tiering
Match model capability to task complexity:
| Model | Best For | Examples |
|-------|----------|----------|
| **Sonnet 4.5** | Orchestration, control flow, coordination | VM execution, captain's chair, workflow routing |
| **Opus 4.5** | Hard/difficult work requiring deep reasoning | Complex analysis, strategic decisions, novel problem-solving |
| **Haiku** | Simple, self-evident tasks (use sparingly) | Classification, summarization, formatting |
**Key insight:** Sonnet 4.5 excels at *orchestrating* agents and managing control flow—it's the ideal model for the OpenProse VM itself and for "captain" agents that coordinate work. Opus 4.5 should be reserved for agents doing genuinely difficult intellectual work. Haiku can handle simple tasks but should generally be avoided where quality matters.
**Detailed task-to-model mapping:**
| Task Type | Model | Rationale |
|-----------|-------|-----------|
| Orchestration, routing, coordination | Sonnet | Fast, good at following structure |
| Investigation, debugging, diagnosis | Sonnet | Structured analysis, checklist-style work |
| Triage, classification, categorization | Sonnet | Clear criteria, deterministic decisions |
| Code review, verification (checklist) | Sonnet | Following defined review criteria |
| Simple implementation, fixes | Sonnet | Applying known patterns |
| Complex multi-file synthesis | Opus | Needs to hold many things in context |
| Novel architecture, strategic planning | Opus | Requires creative problem-solving |
| Ambiguous problems, unclear requirements | Opus | Needs to reason through uncertainty |
**Rule of thumb:** If you can write a checklist for the task, Sonnet can do it. If the task requires genuine creativity or navigating ambiguity, use Opus.
```prose
agent captain:
model: sonnet # Orchestration and coordination
persist: true # Execution-scoped (dies with run)
prompt: "You coordinate the team and review work"
agent researcher:
model: opus # Hard analytical work
prompt: "You perform deep research and analysis"
agent formatter:
model: haiku # Simple transformation (use sparingly)
prompt: "You format text into consistent structure"
agent preferences:
model: sonnet
persist: user # User-scoped (survives across projects)
prompt: "You remember user preferences and patterns"
# Captain orchestrates, specialists do the hard work
session: captain
prompt: "Plan the research approach"
let findings = session: researcher
prompt: "Investigate the technical architecture"
resume: captain
prompt: "Review findings and determine next steps"
context: findings
```
#### context-minimization
Pass only relevant context. Large contexts slow processing and increase costs.
```prose
# Bad: Passing everything
session "Write executive summary"
context: [raw_data, analysis, methodology, appendices, references]
# Good: Pass only what's needed
let key_findings = session "Extract key findings from analysis"
context: analysis
session "Write executive summary"
context: key_findings
```
#### early-termination
Exit loops as soon as the goal is achieved. Don't iterate unnecessarily.
```prose
# The condition is checked each iteration
loop until **solution found and verified** (max: 10):
session "Generate potential solution"
session "Verify solution correctness"
# Exits immediately when condition is met, not after max iterations
```
#### early-signal-exit
When observing or monitoring, exit as soon as you have a definitive answer—don't wait for the full observation window.
```prose
# Good: Exit on signal
let observation = session: observer
prompt: "Watch the stream. Signal immediately if you detect a blocking error."
timeout: 120s
early_exit: **blocking_error detected**
# Bad: Fixed observation window
loop 30 times:
resume: observer
prompt: "Keep watching..." # Even if error was obvious at iteration 2
```
This respects signals when they arrive rather than waiting for arbitrary timeouts.
#### defaults-over-prompts
For standard configuration, use constants or environment variables. Only prompt when genuinely variable.
```prose
# Good: Sensible defaults
const API_URL = "https://api.example.com"
const TEST_PROGRAM = "# Simple test\nsession 'Hello'"
# Slower: Prompting for known values
let api_url = input "Enter API URL" # Usually the same value
let program = input "Enter test program" # Usually the same value
```
If 90% of runs use the same value, hardcode it. Let users override via CLI args if needed.
#### race-for-speed
When any valid result suffices, race multiple approaches and take the first success.
```prose
parallel ("first"):
session "Try algorithm A"
session "Try algorithm B"
session "Try algorithm C"
# Continues as soon as any approach completes
session "Use winning result"
```
#### batch-similar-work
Group similar operations to amortize overhead. One session with structured output beats many small sessions.
```prose
# Inefficient: Many small sessions
for file in files:
session "Analyze {file}"
# Efficient: Batch analysis
session "Analyze all files and return structured findings for each"
context: files
```
---
## Self-Improvement Patterns
#### self-verification-in-prompt
For tasks that would otherwise require a separate verifier, include verification as the final step in the prompt. This saves a round-trip while maintaining rigor.
```prose
# Good: Combined work + self-verification
agent investigator:
model: sonnet
prompt: """Diagnose the error.
1. Examine code paths
2. Check logs and state
3. Form hypothesis
4. BEFORE OUTPUTTING: Verify your evidence supports your conclusion.
Output only if confident. If uncertain, state what's missing."""
# Slower: Separate verifier agent
let diagnosis = session: researcher
prompt: "Investigate the error"
let verification = session: verifier
prompt: "Verify this diagnosis" # Extra round-trip
context: diagnosis
```
Use a separate verifier when you need genuine adversarial review (different perspective), but for self-consistency checks, bake verification into the prompt.
#### iterative-refinement
Use feedback loops to progressively improve outputs. Each iteration builds on the previous.
```prose
let draft = session "Create initial draft"
loop until **draft meets quality bar** (max: 5):
let critique = session "Critically evaluate this draft"
context: draft
draft = session "Improve draft based on critique"
context: [draft, critique]
session "Finalize and publish"
context: draft
```
#### multi-perspective-review
Gather diverse viewpoints before synthesis. Different lenses catch different issues.
```prose
parallel:
user_perspective = session "Evaluate from end-user viewpoint"
tech_perspective = session "Evaluate from engineering viewpoint"
business_perspective = session "Evaluate from business viewpoint"
session "Synthesize feedback and prioritize improvements"
context: { user_perspective, tech_perspective, business_perspective }
```
#### adversarial-validation
Use one agent to challenge another's work. Adversarial pressure improves robustness.
```prose
let proposal = session "Generate proposal"
let critique = session "Find flaws and weaknesses in this proposal"
context: proposal
let defense = session "Address each critique with evidence or revisions"
context: [proposal, critique]
session "Produce final proposal incorporating valid critiques"
context: [proposal, critique, defense]
```
#### consensus-building
For critical decisions, require agreement between independent evaluators.
```prose
parallel:
eval1 = session "Independently evaluate the solution"
eval2 = session "Independently evaluate the solution"
eval3 = session "Independently evaluate the solution"
loop until **evaluators agree** (max: 3):
session "Identify points of disagreement"
context: { eval1, eval2, eval3 }
parallel:
eval1 = session "Reconsider position given other perspectives"
context: { eval1, eval2, eval3 }
eval2 = session "Reconsider position given other perspectives"
context: { eval1, eval2, eval3 }
eval3 = session "Reconsider position given other perspectives"
context: { eval1, eval2, eval3 }
session "Document consensus decision"
context: { eval1, eval2, eval3 }
```
---
## Maintainability Patterns
#### descriptive-agent-names
Name agents for their role, not their implementation. Names should convey purpose.
```prose
# Good: Role-based naming
agent code-reviewer:
agent technical-writer:
agent data-analyst:
# Bad: Implementation-based naming
agent opus-agent:
agent session-1-handler:
agent helper:
```
#### prompt-as-contract
Write prompts that specify expected inputs and outputs. Clear contracts prevent misunderstandings.
```prose
agent json-extractor:
model: haiku
prompt: """
Extract structured data from text.
Input: Unstructured text containing entity information
Output: JSON object with fields: name, date, amount, status
If a field cannot be determined, use null.
Never invent information not present in the input.
"""
```
#### separation-of-concerns
Each session should do one thing well. Combine simple sessions rather than creating complex ones.
```prose
# Good: Single responsibility per session
let data = session "Fetch and validate input data"
let analysis = session "Analyze data for patterns"
context: data
let recommendations = session "Generate recommendations from analysis"
context: analysis
session "Format recommendations as report"
context: recommendations
# Bad: God session
session "Fetch data, analyze it, generate recommendations, and format a report"
```
#### explicit-context-flow
Make data flow visible through explicit context passing. Avoid relying on implicit conversation history.
```prose
# Good: Explicit flow
let step1 = session "First step"
let step2 = session "Second step"
context: step1
let step3 = session "Third step"
context: [step1, step2]
# Bad: Implicit flow (relies on conversation state)
session "First step"
session "Second step using previous results"
session "Third step using all previous"
```
---
## Performance Patterns
#### lazy-evaluation
Defer expensive operations until their results are needed. Don't compute what might not be used.
```prose
session "Assess situation"
if **detailed analysis needed**:
# Expensive operations only when necessary
parallel:
deep_analysis = session "Perform deep analysis"
model: opus
historical = session "Gather historical comparisons"
session "Comprehensive report"
context: { deep_analysis, historical }
else:
session "Quick summary"
model: haiku
```
#### progressive-disclosure
Start with fast, cheap operations. Escalate to expensive ones only when needed.
```prose
# Tier 1: Fast screening (haiku)
let initial = session "Quick assessment"
model: haiku
if **needs deeper review**:
# Tier 2: Moderate analysis (sonnet)
let detailed = session "Detailed analysis"
model: sonnet
context: initial
if **needs expert review**:
# Tier 3: Deep reasoning (opus)
session "Expert-level analysis"
model: opus
context: [initial, detailed]
```
#### work-stealing
Use `parallel ("any", count: N)` to get results as fast as possible from a pool of workers.
```prose
# Get 3 good ideas as fast as possible from 5 parallel attempts
parallel ("any", count: 3, on-fail: "ignore"):
session "Generate creative solution approach 1"
session "Generate creative solution approach 2"
session "Generate creative solution approach 3"
session "Generate creative solution approach 4"
session "Generate creative solution approach 5"
session "Select best from the first 3 completed"
```
---
## Composition Patterns
#### workflow-template
Create blocks that encode entire workflow patterns. Instantiate with different parameters.
```prose
block research-report(topic, depth):
let research = session "Research {topic} at {depth} level"
let analysis = session "Analyze findings about {topic}"
context: research
let report = session "Write {depth}-level report on {topic}"
context: [research, analysis]
# Instantiate for different needs
do research-report("market trends", "executive")
do research-report("technical architecture", "detailed")
do research-report("competitive landscape", "comprehensive")
```
#### middleware-pattern
Wrap sessions with cross-cutting concerns like logging, timing, or validation.
```prose
block with-validation(task, validator):
let result = session "{task}"
let valid = session "{validator}"
context: result
if **validation failed**:
throw "Validation failed for: {task}"
do with-validation("Generate SQL query", "Check SQL for injection vulnerabilities")
do with-validation("Generate config file", "Validate config syntax")
```
#### circuit-breaker
After repeated failures, stop trying and fail fast. Prevents cascading failures.
```prose
let failures = 0
let max_failures = 3
loop while **service needed and failures < max_failures** (max: 10):
try:
session "Call external service"
# Reset on success
failures = 0
catch:
failures = failures + 1
if **failures >= max_failures**:
session "Circuit open - using fallback"
throw "Service unavailable"
```
---
## Observability Patterns
#### checkpoint-narration
For long workflows, emit progress markers. Helps with debugging and monitoring.
```prose
session "Phase 1: Data Collection"
# ... collection work ...
session "Phase 2: Analysis"
# ... analysis work ...
session "Phase 3: Report Generation"
# ... report work ...
session "Phase 4: Quality Assurance"
# ... QA work ...
```
#### structured-output-contracts
Request structured outputs that can be reliably parsed and validated.
```prose
agent structured-reviewer:
model: sonnet
prompt: """
Always respond with this exact JSON structure:
{
"verdict": "pass" | "fail" | "needs_review",
"issues": [{"severity": "high"|"medium"|"low", "description": "..."}],
"suggestions": ["..."]
}
"""
let review = session: structured-reviewer
prompt: "Review this code for security issues"
```
---
## Summary
The most effective OpenProse programs combine these patterns:
1. **Structure**: Parallelize independent work, use blocks for reuse
2. **Robustness**: Bound loops, handle errors, retry transient failures
3. **Efficiency**: Tier models, minimize context, terminate early
4. **Quality**: Iterate, get multiple perspectives, validate adversarially
5. **Maintainability**: Name clearly, separate concerns, make flow explicit
Choose patterns based on your specific constraints. A quick prototype prioritizes speed over robustness. A production workflow prioritizes reliability over cost. A research exploration prioritizes thoroughness over efficiency.

role: system-prompt-enforcement
summary: |
Strict system prompt addition for OpenProse VM instances. This enforces
that the agent ONLY executes .prose programs and embodies the VM correctly.
Append this to system prompts for dedicated OpenProse execution instances.
---
# OpenProse VM System Prompt Enforcement
**⚠️ CRITICAL: THIS INSTANCE IS DEDICATED TO OPENPROSE EXECUTION ONLY ⚠️**
This agent instance is configured exclusively for executing OpenProse (`.prose`) programs. You MUST NOT execute, interpret, or respond to any non-Prose tasks. If a user requests anything other than a `prose` command or `.prose` program execution, you MUST refuse and redirect them to use a general-purpose agent.
## Your Role: You ARE the OpenProse VM
You are not simulating a virtual machine—you **ARE** the OpenProse VM. When executing a `.prose` program:
- **Your conversation history** = The VM's working memory
- **Your Task tool calls** = The VM's instruction execution
- **Your state tracking** = The VM's execution trace
- **Your judgment on `**...**`** = The VM's intelligent evaluation
### Core Execution Principles
1. **Strict Structure**: Follow the program structure exactly as written
2. **Intelligent Evaluation**: Use judgment only for discretion conditions (`**...**`)
3. **Real Execution**: Each `session` spawns a real subagent via Task tool
4. **State Persistence**: Track state in `.prose/runs/{id}/` or via narration protocol
## Execution Model
### Sessions = Function Calls
Every `session` statement triggers a Task tool call:
```prose
session "Research quantum computing"
```
Execute as:
```
Task({
description: "OpenProse session",
prompt: "Research quantum computing",
subagent_type: "general-purpose"
})
```
### Context Passing (By Reference)
The VM passes context **by reference**, never by value:
```
Context (by reference):
- research: .prose/runs/{id}/bindings/research.md
Read this file to access the content. The VM never holds full binding values.
```
### Parallel Execution
`parallel:` blocks spawn multiple sessions concurrently—call all Task tools in a single response:
```prose
parallel:
a = session "Task A"
b = session "Task B"
```
Execute by calling both Task tools simultaneously, then wait for all to complete.
### Persistent Agents
- `session: agent` = Fresh start (ignores memory)
- `resume: agent` = Load memory, continue with context
For `resume:`, include the agent's memory file path and instruct the subagent to read/update it.
### Control Flow
- **Loops**: Evaluate condition, execute body, repeat until condition met or max reached
- **Try/Catch**: Execute try, catch on error, always execute finally
- **Choice/If**: Evaluate conditions, execute first matching branch only
- **Blocks**: Push frame, bind arguments, execute body, pop frame
## State Management
Default: File-system state in `.prose/runs/{id}/`
- `state.md` = VM execution state (written by VM only)
- `bindings/{name}.md` = Variable values (written by subagents)
- `agents/{name}/memory.md` = Persistent agent memory
Subagents write their outputs directly to binding files and return confirmation messages (not full content) to the VM.
## File Location Index
**Do NOT search for OpenProse documentation files.** All skill files are installed in the skills directory. Use the following paths (with placeholder `{OPENPROSE_SKILL_DIR}` that will be replaced with the actual skills directory path):
| File | Location | Purpose |
| ----------------------- | --------------------------------------------- | ---------------------------------------------- |
| `prose.md` | `{OPENPROSE_SKILL_DIR}/prose.md` | VM semantics (load to run programs) |
| `state/filesystem.md` | `{OPENPROSE_SKILL_DIR}/state/filesystem.md` | File-based state (default, load with VM) |
| `state/in-context.md` | `{OPENPROSE_SKILL_DIR}/state/in-context.md` | In-context state (on request) |
| `state/sqlite.md` | `{OPENPROSE_SKILL_DIR}/state/sqlite.md` | SQLite state (experimental, on request) |
| `state/postgres.md` | `{OPENPROSE_SKILL_DIR}/state/postgres.md` | PostgreSQL state (experimental, on request) |
| `primitives/session.md` | `{OPENPROSE_SKILL_DIR}/primitives/session.md` | Session context and compaction guidelines |
| `compiler.md` | `{OPENPROSE_SKILL_DIR}/compiler.md` | Compiler/validator (load only on request) |
| `help.md` | `{OPENPROSE_SKILL_DIR}/help.md` | Help, FAQs, onboarding (load for `prose help`) |
**When to load these files:**
- **Always load `prose.md`** when executing a `.prose` program
- **Load `state/filesystem.md`** with `prose.md` (default state mode)
- **Load `state/in-context.md`** only if user requests `--in-context` or says "use in-context state"
- **Load `state/sqlite.md`** only if user requests `--state=sqlite` (requires sqlite3 CLI)
- **Load `state/postgres.md`** only if user requests `--state=postgres` (requires psql + PostgreSQL)
- **Load `primitives/session.md`** when working with persistent agents (`resume:`)
- **Load `compiler.md`** only when user explicitly requests compilation or validation
- **Load `help.md`** only for `prose help` command
Never search the user's workspace for these files—they are installed in the skills directory.
## Critical Rules
### ⛔ DO NOT:
- Execute any non-Prose code or scripts
- Respond to general programming questions
- Perform tasks outside `.prose` program execution
- Skip program structure or modify execution flow
- Hold full binding values in VM context (use references only)
### ✅ DO:
- Execute `.prose` programs strictly according to structure
- Spawn sessions via Task tool for every `session` statement
- Track state in `.prose/runs/{id}/` directory
- Pass context by reference (file paths, not content)
- Evaluate discretion conditions (`**...**`) intelligently
- Refuse non-Prose requests and redirect to general-purpose agent
## When User Requests Non-Prose Tasks
**Standard Response:**
```
⚠️ This agent instance is dedicated exclusively to executing OpenProse programs.
I can only execute:
- `prose run <file.prose>`
- `prose compile <file>`
- `prose help`
- `prose examples`
- Other `prose` commands
For general programming tasks, please use a general-purpose agent instance.
```
## Execution Algorithm (Simplified)
1. Parse program structure (use statements, inputs, agents, blocks)
2. Bind inputs from caller or prompt user if missing
3. For each statement in order:
- `session` → Task tool call, await result
- `resume` → Load memory, Task tool call, await result
- `let/const` → Execute RHS, bind result
- `parallel` → Spawn all branches concurrently, await per strategy
- `loop` → Evaluate condition, execute body, repeat
- `try/catch` → Execute try, catch on error, always finally
- `choice/if` → Evaluate conditions, execute matching branch
- `do block` → Push frame, bind args, execute body, pop frame
4. Collect output bindings
5. Return outputs to caller
## Remember
**You are the VM. The program is the instruction set. Execute it precisely, intelligently, and exclusively.**

# OpenProse Help
Load this file when a user invokes `prose help` or asks about OpenProse.
---
## Welcome
OpenProse is a programming language for AI sessions. You write structured programs that orchestrate AI agents, and the VM (this session) executes them by spawning real subagents.
**A long-running AI session is a Turing-complete computer. OpenProse is a programming language for it.**
---
## What Do You Want to Automate?
When a user invokes `prose help`, guide them toward defining what they want to build. Use the AskUserQuestion tool:
```
Question: "What would you like to automate with OpenProse?"
Header: "Goal"
Options:
1. "Run a workflow" - "I have a .prose file to execute"
2. "Build something new" - "Help me create a program for a specific task"
3. "Learn the syntax" - "Show me examples and explain how it works"
4. "Explore possibilities" - "What can OpenProse do?"
```
**After the user responds:**
- **Run a workflow**: Ask for the file path, then load `prose.md` and execute
- **Build something new**: Ask them to describe their task, then help write a .prose program (load `guidance/patterns.md`)
- **Learn the syntax**: Show examples from `examples/`, explain the VM model
- **Explore possibilities**: Walk through key examples like `37-the-forge.prose` or `28-gas-town.prose`
**Send a poll telemetry event** with their selection (see SKILL.md telemetry section).
---

## FAQs
### What AI assistants are supported?
Claude Code, OpenCode, and Amp. Any harness that runs a sufficiently intelligent model and supports primitives like subagents are considered "Prose Complete".
### How is this a VM?
LLMs are simulators—when given a detailed system description, they don't just describe it, they simulate it. The `prose.md` spec describes a VM with enough fidelity that reading it induces simulation. But simulation with sufficient fidelity is implementation: each session spawns a real subagent, outputs are real artifacts, state persists in conversation history or files. The simulation is the execution.
### What's "intelligent IoC"?
Traditional IoC containers (Spring, Guice) wire up dependencies from configuration files. OpenProse's container is an AI session that wires up agents using understanding. It doesn't just match names—it understands context, intent, and can make intelligent decisions about execution.
### This looks like Python.
The syntax is intentionally familiar—Python's indentation-based structure is readable and self-evident. But the semantics are entirely different. OpenProse has no functions, no classes, no general-purpose computation. It has agents, sessions, and control flow. The design principle: structured but self-evident, unambiguous interpretation with minimal documentation.
### Why not English?
English is already an agent framework—we're not replacing it, we're structuring it. Plain English doesn't distinguish sequential from parallel, doesn't specify retry counts, doesn't scope variables. OpenProse uses English exactly where ambiguity is a feature (inside `**...**`), and structure everywhere else. The fourth wall syntax lets you lean on AI judgment precisely when you want to.
### Why not YAML?
We started with YAML. The problem: loops, conditionals, and variable declarations aren't self-evident in YAML—and when you try to make them self-evident, it gets verbose and ugly. More fundamentally, YAML optimizes for machine parseability. OpenProse optimizes for intelligent machine legibility. It doesn't need to be parsed—it needs to be understood. That's a different design target entirely.
### Why not LangChain/CrewAI/AutoGen?
Those are orchestration libraries—they coordinate agents from outside. OpenProse runs inside the agent session—the session itself is the IoC container. This means zero external dependencies and portability across any AI assistant. Switch from Claude Code to Codex? Your .prose files still work.
---
## Syntax at a Glance
```prose
session "prompt" # Spawn subagent
agent name: # Define agent template
let x = session "..." # Capture result
parallel: # Concurrent execution
repeat N: # Fixed loop
for x in items: # Iteration
loop until **condition**: # AI-evaluated loop
try: ... catch: ... # Error handling
if **condition**: ... # Conditional
choice **criteria**: option # AI-selected branch
block name(params): # Reusable block
do blockname(args) # Invoke block
items | map: ... # Pipeline
```
For complete syntax and validation rules, see `compiler.md`.
---
## Examples
The `examples/` directory contains 37 example programs:
| Range | Category |
|-------|----------|
| 01-08 | Basics (hello world, research, code review, debugging) |
| 09-12 | Agents and skills |
| 13-15 | Variables and composition |
| 16-19 | Parallel execution |
| 20-21 | Loops and pipelines |
| 22-23 | Error handling |
| 24-27 | Advanced (choice, conditionals, blocks, interpolation) |
| 28 | Gas Town (multi-agent orchestration) |
| 29-31 | Captain's chair pattern (persistent orchestrator) |
| 33-36 | Production workflows (PR auto-fix, content pipeline, feature factory, bug hunter) |
| 37 | The Forge (build a browser from scratch) |
**Recommended starting points:**
- `01-hello-world.prose` - Simplest possible program
- `16-parallel-reviews.prose` - See parallel execution
- `37-the-forge.prose` - Watch AI build a web browser

# OpenProse Standard Library
Core programs that ship with OpenProse. Production-quality, well-tested programs for common tasks.
## Programs
### Evaluation & Improvement
| Program | Description |
|---------|-------------|
| `inspector.prose` | Post-run analysis for runtime fidelity and task effectiveness |
| `vm-improver.prose` | Analyzes inspections and proposes PRs to improve the VM |
| `program-improver.prose` | Analyzes inspections and proposes PRs to improve .prose source |
| `cost-analyzer.prose` | Token usage and cost pattern analysis |
| `calibrator.prose` | Validates light evaluations against deep evaluations |
| `error-forensics.prose` | Root cause analysis for failed runs |
### Memory
| Program | Description |
|---------|-------------|
| `user-memory.prose` | Cross-project persistent personal memory |
| `project-memory.prose` | Project-scoped institutional memory |
## The Improvement Loop
The evaluation programs form a recursive improvement cycle:
```
┌─────────────────────────────────────────────────────────────┐
│ │
│ Run Program ──► Inspector ──► VM Improver ──► PR │
│ ▲ │ │
│ │ ▼ │
│ │ Program Improver ──► PR │
│ │ │ │
│ └────────────────┘ │
│ │
└─────────────────────────────────────────────────────────────┘
```
Supporting analysis:
- **cost-analyzer** — Where does the money go? Optimization opportunities.
- **calibrator** — Are cheap evaluations reliable proxies for expensive ones?
- **error-forensics** — Why did a run fail? Root cause analysis.
## Usage
```bash
# Inspect a completed run
prose run lib/inspector.prose
# Inputs: run_path, depth (light|deep), target (vm|task|all)
# Propose VM improvements
prose run lib/vm-improver.prose
# Inputs: inspection_path, prose_repo
# Propose program improvements
prose run lib/program-improver.prose
# Inputs: inspection_path, run_path
# Analyze costs
prose run lib/cost-analyzer.prose
# Inputs: run_path, scope (single|compare|trend)
# Validate light vs deep evaluation
prose run lib/calibrator.prose
# Inputs: run_paths, sample_size
# Investigate failures
prose run lib/error-forensics.prose
# Inputs: run_path, focus (vm|program|context|external)
# Memory programs (recommend sqlite+ backend)
prose run lib/user-memory.prose --backend sqlite+
# Inputs: mode (teach|query|reflect), content
prose run lib/project-memory.prose --backend sqlite+
# Inputs: mode (ingest|query|update|summarize), content
```
## Memory Programs
The memory programs use persistent agents to accumulate knowledge:
**user-memory** (`persist: user`)
- Learns your preferences, decisions, patterns across all projects
- Remembers mistakes and lessons learned
- Answers questions from accumulated knowledge
**project-memory** (`persist: project`)
- Understands this project's architecture and decisions
- Tracks why things are the way they are
- Answers questions with project-specific context
Both recommend `--backend sqlite+` for durable persistence.
## Design Principles
1. **Production-ready** — Tested, documented, handles edge cases
2. **Composable** — Can be imported via `use` in other programs
3. **User-scoped state** — Cross-project utilities use `persist: user`
4. **Minimal dependencies** — No external services required
5. **Clear contracts** — Well-defined inputs and outputs
6. **Incremental value** — Useful in simple mode, more powerful with depth

Fetch current pricing from the pricing URL provided in your prompt.

- Each contains token usage that MUST be counted

- usage.input_tokens, usage.output_tokens
- usage.cache_creation_input_tokens, usage.cache_read_input_tokens

# Session Context Management
You are a subagent operating within an OpenProse program. This document explains how to work with the context you receive and how to preserve state for future sessions.
---
## 1. Understanding Your Context Layers
When you start, you receive context from multiple sources. Understand what each represents:
### 1.1 Outer Agent State
The **outer agent state** is context from the orchestrating VM or parent agent. It tells you:
- What program is running
- Where you are in the execution flow
- What has happened in prior steps
Look for markers like:
```
## Execution Context
Program: feature-implementation.prose
Current phase: Implementation
Prior steps completed: [plan, design]
```
**How to use it:** This orients you. You're not starting from scratch—you're continuing work that's already in progress. Reference prior steps when relevant.
### 1.2 Persistent Agent Memory
If you are a **persistent agent**, you'll receive a memory file with your prior observations and decisions. This is YOUR accumulated knowledge from previous segments.
Look for:
```
## Agent Memory: [your-name]
```
**How to use it:** This is your continuity. You reviewed something yesterday; you remember that review today. Reference your prior decisions. Build on your accumulated understanding. Don't contradict yourself without acknowledging the change.
### 1.3 Task Context
The **task context** is the specific input for THIS session—the code to review, the plan to evaluate, the feature to implement.
Look for:
```
## Task Context
```
or
```
Context provided:
---
[specific content]
---
```
**How to use it:** This is what you're working on RIGHT NOW. Your primary focus. The other context layers inform how you approach this.
### 1.4 Layering Order
When context feels overwhelming, process in this order:
1. **Skim outer state** → Where am I in the bigger picture?
2. **Read your memory** → What do I already know?
3. **Focus on task context** → What am I doing right now?
4. **Synthesize** → How does my prior knowledge inform this task?
### 1.5 Execution Scope (Block Invocations)
If you're running inside a block invocation, you'll receive execution scope information:
```
Execution scope:
execution_id: 43
block: process
depth: 3
parent_execution_id: 42
```
**What this tells you:**
| Field | Meaning |
|-------|---------|
| `execution_id` | Unique ID for this specific block invocation |
| `block` | Name of the block you're executing within |
| `depth` | How deep in the call stack (1 = first level) |
| `parent_execution_id` | The invoking frame's ID (for scope chain) |
**How to use it:**
1. **Include in your binding output**: When writing bindings, include the `execution_id` in the filename and frontmatter so the VM can track scope correctly.
2. **Understand variable isolation**: Your bindings won't collide with other invocations of the same block. If the block calls itself recursively, each invocation has its own `execution_id`.
3. **Context references are pre-resolved**: The VM resolves variable references before passing context to you. You don't need to walk the scope chain—the VM already did.
**Example:** If a recursive `process` block is at depth 5, there are 5 separate `execution_id` values, each with their own local bindings. Your session only sees the current frame's context.
---
## 2. Working with Persistent State
If you're a persistent agent, you maintain state across sessions via a memory file.
### Two Distinct Outputs
Persistent agents have **two separate outputs** that must not be confused:
| Output | What It Is | Where It Goes | Purpose |
|--------|------------|---------------|---------|
| **Binding** | The result of THIS task | `bindings/{name}.md` or database | Passed to other sessions via `context:` |
| **Memory** | Your accumulated knowledge | `agents/{name}/memory.md` or database | Carried forward to YOUR future invocations |
**The binding is task-specific.** If you're asked to "review the plan," the binding contains your review.
**The memory is agent-specific.** It contains your accumulated understanding, decisions, and concerns across ALL your invocations—not just this one.
These are written to **different locations** and serve **different purposes**. Always write both.
### 2.1 Reading Your Memory
At session start, your memory file is provided. It contains:
- **Current Understanding**: Your overall grasp of the project/task
- **Decisions Made**: What you've decided and why
- **Open Concerns**: Things you're watching for
- **Recent Segments**: What happened in recent sessions
**Read it carefully.** Your memory is your continuity. A persistent agent that ignores its memory is just a stateless agent with extra steps.
### 2.2 Building on Prior Knowledge
When you encounter something related to your memory:
- Reference it explicitly: "In my previous review, I noted X..."
- Build on it: "Given that I already approved the plan, I'm now checking implementation alignment..."
- Update it if wrong: "I previously thought X, but now I see Y..."
### 2.3 Maintaining Consistency
Your decisions should be consistent across segments unless you explicitly change your position. If you approved a plan in segment 1, don't reject the same approach in segment 3 without acknowledging the change and explaining why.
---
## 3. Memory Compaction Guidelines
At the end of your session, you'll be asked to update your memory file. This is **compaction**—preserving what matters for future sessions.
### 3.1 Compaction is NOT Summarization
**Wrong approach:** "I reviewed the code and found some issues."
This loses all useful information. A summary generalizes; compaction preserves specifics.
**Right approach:** "Reviewed auth module (src/auth/login.ts:45-120). Found: (1) SQL injection risk in query builder line 67, (2) missing rate limiting on login endpoint, (3) good error handling pattern worth reusing. Requested fixes for #1 and #2, approved overall structure."
### 3.2 What to Preserve
Preserve **specific details** that future-you will need:
| Preserve | Example |
| ---------------------------- | -------------------------------------------------------- |
| **Specific locations** | "src/auth/login.ts:67" not "the auth code" |
| **Exact findings** | "SQL injection in query builder" not "security issues" |
| **Decisions with rationale** | "Approved because X" not just "Approved" |
| **Numbers and thresholds** | "Coverage at 73%, target is 80%" not "coverage is low" |
| **Names and identifiers** | "User.authenticate() method" not "the login function" |
| **Open questions** | "Need to verify: does rate limiter apply to OAuth flow?" |
### 3.3 What to Drop
Drop information that won't help future sessions:
| Drop | Why |
| ---------------- | --------------------------------------------------------------------------- |
| Reasoning chains | The conclusion matters, not how you got there |
| False starts | You considered X but chose Y—just record Y and a brief note about why not X |
| Obvious context | Don't repeat the task prompt back |
| Verbose quotes | Reference by location, don't copy large blocks |
### 3.4 Compaction Structure
Update your memory file in this structure:
```markdown
## Current Understanding
[What you know about the overall project/task—update, don't replace entirely]
## Decisions Made
[Append new decisions with dates and rationale]
- [date]: [decision] — [why]
## Open Concerns
[Things to watch for in future sessions—add new, remove resolved]
## Segment [N] Summary
[What happened THIS session—specific, not general]
- Reviewed: [what, where]
- Found: [specific findings]
- Decided: [specific decisions]
- Next: [what should happen next]
```
### 3.5 Compaction Examples
**Bad compaction (too general):**
```
## Segment 3 Summary
Reviewed the implementation. Found some issues. Requested changes.
```
**Good compaction (specific and useful):**
```
## Segment 3 Summary
- Reviewed: Step 2 implementation (UserService.ts, AuthController.ts)
- Found:
- Missing null check in UserService.getById (line 34)
- AuthController.login not using the approved error format from segment 1
- Good: Transaction handling follows pattern I recommended
- Decided: Request fixes for null check and error format before proceeding
- Next: Re-review after fixes, then approve for step 3
```
### 3.6 The Specificity Test
Before finalizing your compaction, ask: "If I read only this summary in a week, could I understand exactly what happened and make consistent follow-up decisions?"
If the answer is no, add more specifics.
---
## 4. Context Size Management
### 4.1 When Your Memory Gets Long
Over many segments, your memory file grows. When it becomes unwieldy:
1. **Preserve recent segments in full** (last 2-3)
2. **Compress older segments** into key decisions only
3. **Archive ancient history** as bullet points
```markdown
## Recent Segments (full detail)
[Segments 7-9]
## Earlier Segments (compressed)
- Segment 4-6: Completed initial implementation review, approved with minor fixes
- Segment 1-3: Established review criteria, approved design doc
## Key Historical Decisions
- Chose JWT over session tokens (segment 2)
- Established 80% coverage threshold (segment 1)
```
### 4.2 When Task Context is Large
If you receive very large task context (big code blocks, long documents):
1. **Don't try to hold it all** — reference by location
2. **Note what you examined** — "Reviewed lines 1-200, focused on auth flow"
3. **Record specific locations** — future sessions can re-examine if needed
---
## 5. Signaling to the VM
The OpenProse VM reads your output to determine next steps. Help it by being clear:
### 5.1 Decision Signals
When you make a decision that affects control flow, be explicit:
```
DECISION: Proceed with implementation
RATIONALE: Plan addresses all concerns raised in previous review
```
or
```
DECISION: Request revision
ISSUES:
1. [specific issue]
2. [specific issue]
REQUIRED CHANGES: [what needs to happen]
```
### 5.2 Concern Signals
When you notice something that doesn't block progress but should be tracked:
```
CONCERN: [specific concern]
SEVERITY: [low/medium/high]
TRACKING: [what to watch for]
```
### 5.3 Completion Signals
When your segment is complete:
```
SEGMENT COMPLETE
MEMORY UPDATES:
- [what to add to Current Understanding]
- [decisions to record]
- [concerns to track]
READY FOR: [what should happen next]
```
---
## 6. Writing Output Files
When using file-based state (see `../state/filesystem.md`), the VM tells you where to write your output. You must write your results directly to the filesystem.
### 6.1 Binding Output Files
For regular sessions with output capture (`let x = session "..."`), write to the specified binding path:
**Path format:** `.prose/runs/{run-id}/bindings/{name}.md`
**Path format (inside block invocation):** `.prose/runs/{run-id}/bindings/{name}__{execution_id}.md`
**File format:**
````markdown
# {name}
kind: {let|const|output|input}
execution_id: {id} # Include if inside a block invocation (omit for root scope)
source:
```prose
{the source code that created this binding}
```
````
---
{Your actual output here}
````
**Example:**
```markdown
# research
kind: let
source:
```prose
let research = session: researcher
prompt: "Research AI safety"
````
---
AI safety research covers several key areas:
1. **Alignment** - Ensuring AI systems pursue intended goals
2. **Robustness** - Making systems resilient to edge cases
3. **Interpretability** - Understanding how models make decisions
Key papers include Amodei et al. (2016) on concrete problems...
````
### 6.2 Anonymous Session Output
Sessions without explicit capture (`session "..."` without `let x =`) still produce output. These are written with `anon_` prefix:
**Path:** `.prose/runs/{run-id}/bindings/anon_001.md`
The VM assigns sequential numbers. Write the same format but note the binding came from an anonymous session:
```markdown
# anon_003
kind: let
source:
```prose
session "Analyze the codebase for security issues"
````
---
Security analysis found the following issues...
````
### 6.3 Persistent Agent Memory Output
If you are a persistent agent (invoked with `resume:`), you have additional responsibilities:
1. **Read your memory file first**
2. **Process the task using memory + context**
3. **Update your memory file** with compacted state
4. **Write a segment file** recording this session
**Memory file path:** `.prose/runs/{run-id}/agents/{name}/memory.md` (or `.prose/agents/{name}/` for project-scoped, or `~/.prose/agents/{name}/` for user-scoped)
**Segment file path:** `.prose/runs/{run-id}/agents/{name}/{name}-{NNN}.md`
**Memory file format:**
```markdown
# Agent Memory: {name}
## Current Understanding
{Your accumulated knowledge about the project/task}
## Decisions Made
- {date}: {decision} — {rationale}
- {date}: {decision} — {rationale}
## Open Concerns
- {Concern 1}
- {Concern 2}
````
**Segment file format:**
```markdown
# Segment {NNN}
timestamp: {ISO8601}
prompt: "{the prompt for this session}"
## Summary
- Reviewed: {what you examined}
- Found: {specific findings}
- Decided: {specific decisions}
- Next: {what should happen next}
```
### 6.4 Output Writing Checklist
Before completing your session:
- [ ] Write your output to the specified binding path
- [ ] If persistent agent: update memory.md
- [ ] If persistent agent: write segment file
- [ ] Use the exact file format specified
- [ ] Include the source code snippet for traceability
---
## 7. Returning to the VM
When your session completes, you return a **confirmation message** to the VM—not your full output. The VM tracks pointers, not values.
### 7.1 What to Return
Your return message should include:
```
Binding written: {name}
Location: {path or database coordinates}
Summary: {1-2 sentence summary of what's in the binding}
```
**Example (filesystem state, root scope):**
```
Binding written: research
Location: .prose/runs/20260116-143052-a7b3c9/bindings/research.md
Summary: Comprehensive AI safety research covering alignment, robustness, and interpretability with 15 key paper citations.
```
**Example (filesystem state, inside block invocation):**
```
Binding written: result
Location: .prose/runs/20260116-143052-a7b3c9/bindings/result__43.md
Execution ID: 43
Summary: Processed chunk into 3 sub-parts for recursive processing.
```
**Example (PostgreSQL state):**
```
Binding written: research
Location: openprose.bindings WHERE name='research' AND run_id='20260116-143052-a7b3c9'
Summary: Comprehensive AI safety research covering alignment, robustness, and interpretability with 15 key paper citations.
```
**Example (PostgreSQL state, inside block invocation):**
```
Binding written: result
Location: openprose.bindings WHERE name='result' AND run_id='20260116-143052-a7b3c9' AND execution_id=43
Execution ID: 43
Summary: Processed chunk into 3 sub-parts for recursive processing.
```
### 7.2 Why Pointers, Not Values
The VM never holds full binding values in its working memory. This is intentional:
1. **Scalability**: Bindings can be arbitrarily large (megabytes, even gigabytes)
2. **RLM patterns**: Enables "environment as variable" where agents query state programmatically
3. **Context efficiency**: The VM's context stays lean regardless of intermediate data size
4. **Concurrent access**: Multiple agents can read/write different bindings simultaneously
### 7.3 What NOT to Return
Do NOT return your full output in the Task tool response. The VM will ignore it.
**Bad:**
```
Here's my research:
AI safety is a field that studies how to create artificial intelligence systems that are beneficial and avoid harmful outcomes. The field encompasses several key areas...
[5000 more words]
```
**Good:**
```
Binding written: research
Location: .prose/runs/20260116-143052-a7b3c9/bindings/research.md
Summary: 5200-word AI safety overview covering alignment, robustness, interpretability, and governance with 15 citations.
```
### 7.4 For Persistent Agents
If you're a persistent agent (invoked with `resume:`), also confirm your memory update:
```
Binding written: analysis
Location: .prose/runs/20260116-143052-a7b3c9/bindings/analysis.md
Summary: Risk assessment identifying 3 critical and 5 moderate concerns.
Memory updated: captain
Location: .prose/runs/20260116-143052-a7b3c9/agents/captain/memory.md
Segment: captain-003.md
```
---
## Summary
As a subagent in an OpenProse program:
1. **Understand your context layers** — outer state, memory, task context
2. **Read context by reference** — access binding files/database directly, load what you need
3. **Build on your memory** — you have continuity, use it
4. **Compact, don't summarize** — preserve specifics, drop reasoning chains
5. **Signal clearly** — help the VM understand your decisions
6. **Test your compaction** — would future-you understand exactly what happened?
7. **Write outputs directly** — persist to the binding location you're given
8. **Return pointers, not values** — the VM tracks locations, not content
Your memory is what makes you persistent. The VM's efficiency depends on you writing outputs and returning confirmations—not dumping full content back through the substrate.

summary: |
File-system state management for OpenProse programs. This approach persists
execution state to the `.prose/` directory, enabling inspection, resumption,
and long-running workflows.

- ../prose.md: VM execution semantics

# File-System State Management
This document describes how the OpenProse VM tracks execution state using **files in the `.prose/` directory**. This is one of two state management approaches (the other being in-context state in `in-context.md`).
## Overview
File-based state persists all execution artifacts to disk. This enables:
- **Inspection**: See exactly what happened at each step
- **Resumption**: Pick up interrupted programs
- **Long-running workflows**: Handle programs that exceed context limits
- **Debugging**: Trace through execution history
**Key principle:** Files are inspectable artifacts. The directory structure IS the execution state.
---
## Directory Structure
```
# Project-level state (in working directory)
.prose/
├── .env # Config/telemetry (simple key=value format)
├── runs/
│ └── {YYYYMMDD}-{HHMMSS}-{random}/
│ ├── program.prose # Copy of running program
│ ├── state.md # Execution state with code snippets
│ ├── bindings/
│ │ ├── {name}.md # Root scope bindings
│ │ └── {name}__{execution_id}.md # Scoped bindings (block invocations)
│ ├── imports/
│ │ └── {handle}--{slug}/ # Nested program executions (same structure recursively)
│ └── agents/
│ └── {name}/
│ ├── memory.md # Agent's current state
│ ├── {name}-001.md # Historical segments (flattened)
│ ├── {name}-002.md
│ └── ...
└── agents/ # Project-scoped agent memory
└── {name}/
├── memory.md
├── {name}-001.md
└── ...
# User-level state (in home directory)
~/.prose/
└── agents/ # User-scoped agent memory (cross-project)
└── {name}/
├── memory.md
├── {name}-001.md
└── ...
```
### Run ID Format
Format: `{YYYYMMDD}-{HHMMSS}-{random6}`
Example: `20260115-143052-a7b3c9`
No "run-" prefix needed—the directory name makes context obvious.
### Segment Numbering
Segments use 3-digit zero-padded numbers: `captain-001.md`, `captain-002.md`, etc.
If a program exceeds 999 segments, extend to 4 digits: `captain-1000.md`.
---
## File Formats
### `.prose/.env`
Simple key=value configuration file:
```env
OPENPROSE_TELEMETRY=enabled
USER_ID=user-a7b3c9d4e5f6
SESSION_ID=sess-1704326400000-x9y8z7
```
**Why this format:** Self-evident, no JSON parsing needed, familiar to developers.
---
### `state.md`
The execution state file shows the program's current position using **annotated code snippets**. This makes it self-evident where execution is and what has happened.
**Only the VM writes this file.** Subagents never modify `state.md`.
The format shows:
- **Full history** of executed code with inline annotations
- **Current position** clearly marked with status
- **~5-10 lines ahead** of current position (what's coming next)
- **Index** of all bindings and agents with file paths

### `bindings/{name}.md`
All named values (input, output, let, const) are stored as binding files.
```markdown
# research
kind: let
source:
```prose
let research = session: researcher
prompt: "Research AI safety"
```
---
AI safety research covers several key areas including alignment,
robustness, and interpretability. The field has grown significantly
since 2020 with major contributions from...
```
**Structure:**
- Header with binding name
- `kind:` field indicating type (input, output, let, const)
- `source:` code snippet showing origin
- `---` separator
- Actual value below
**The `kind` field distinguishes:**
| Kind | Meaning |
|------|---------|
| `input` | Value received from caller |
| `output` | Value to return to caller |
| `let` | Mutable variable |
| `const` | Immutable variable |
### Anonymous Session Bindings
Sessions without explicit output capture still produce results:
```prose
session "Analyze the codebase" # No `let x = ...` capture
```
These get auto-generated names with an `anon_` prefix:
- `bindings/anon_001.md`
- `bindings/anon_002.md`
- etc.
This ensures all session outputs are persisted and inspectable.
---
### Scoped Bindings (Block Invocations)
When a binding is created inside a block invocation, it's scoped to that execution frame to prevent collisions across recursive calls.
**Naming convention:** `{name}__{execution_id}.md`
Examples:
- `bindings/result__43.md` — binding `result` in execution_id 43
- `bindings/parts__44.md` — binding `parts` in execution_id 44
**File format with execution scope:**
```markdown
# result
kind: let
execution_id: 43
source:
```prose
let result = session "Process chunk"
```
---
Processed chunk into 3 sub-parts...
```
**Scope resolution:** The VM resolves variable references by checking:
1. `{name}__{current_execution_id}.md`
2. `{name}__{parent_execution_id}.md`
3. Continue up the call stack
4. `{name}.md` (root scope)
The first match wins.
**Example directory for recursive calls:**
```
bindings/
├── data.md # Root scope input
├── result__1.md # First process() invocation
├── parts__1.md # Parts from first invocation
├── result__2.md # Recursive call (depth 2)
├── parts__2.md # Parts from depth 2
├── result__3.md # Recursive call (depth 3)
└── ...
```

### Agent Memory Files
#### `agents/{name}/memory.md`
The agent's current accumulated state:
```markdown
# Agent Memory: captain
## Current Understanding
The project is implementing a REST API for user management.
Architecture uses Express + PostgreSQL. Test coverage target is 80%.
## Decisions Made
- 2026-01-15: Approved JWT over session tokens (simpler stateless auth)
- 2026-01-15: Set 80% coverage threshold (balances quality vs velocity)
## Open Concerns
- Rate limiting not yet implemented on login endpoint
- Need to verify OAuth flow works with new token format
```
#### `agents/{name}/{name}-NNN.md` (Segments)
Historical records of each invocation, flattened in the same directory:
```markdown
# Segment 001
timestamp: 2026-01-15T14:32:15Z
prompt: "Review the research findings"
## Summary
- Reviewed: docs from parallel research session
- Found: good coverage of core concepts, missing edge cases
- Decided: proceed with implementation, note gaps for later
- Next: review implementation against identified gaps
```
---
## Who Writes What
| File | Written By |
|------|------------|
| `state.md` | VM only |
| `bindings/{name}.md` | Subagent |
| `agents/{name}/memory.md` | Persistent agent |
| `agents/{name}/{name}-NNN.md` | Persistent agent |
The VM orchestrates; subagents write their own outputs directly to the filesystem. **The VM never holds full binding values—it tracks file paths.**
---
## Subagent Output Writing
When the VM spawns a session, it tells the subagent where to write output.
### For Regular Sessions
```
When you complete this task, write your output to:
.prose/runs/20260115-143052-a7b3c9/bindings/research.md
Format:
# research
kind: let
source:
```prose
let research = session: researcher
prompt: "Research AI safety"
```
---
[Your output here]
```
### For Persistent Agents (resume:)
```
Your memory is at:
.prose/runs/20260115-143052-a7b3c9/agents/captain/memory.md
Read it first to understand your prior context. When done, update it
with your compacted state following the guidelines in primitives/session.md.
Also write your segment record to:
.prose/runs/20260115-143052-a7b3c9/agents/captain/captain-003.md
```
### What Subagents Return to the VM
After writing output, the subagent returns a **confirmation message**—not the full content:
**Root scope (outside block invocations):**
```
Binding written: research
Location: .prose/runs/20260115-143052-a7b3c9/bindings/research.md
Summary: AI safety research covering alignment, robustness, and interpretability with 15 citations.
```
**Inside block invocation (include execution_id):**
```
Binding written: result
Location: .prose/runs/20260115-143052-a7b3c9/bindings/result__43.md
Execution ID: 43
Summary: Processed chunk into 3 sub-parts for recursive processing.
```
The VM records the location and continues. It does NOT read the file—it passes the reference to subsequent sessions that need the context.
---
## Imports Recursive Structure
Imported programs use the **same unified structure recursively**:
```
.prose/runs/{id}/imports/{handle}--{slug}/
├── program.prose
├── state.md
├── bindings/
│ └── {name}.md
├── imports/ # Nested imports go here
│ └── {handle2}--{slug2}/
│ └── ...
└── agents/
└── {name}/
```
This allows unlimited nesting depth while maintaining consistent structure at every level.
---
## Memory Scoping for Persistent Agents
| Scope | Declaration | Path | Lifetime |
|-------|-------------|------|----------|
| Execution (default) | `persist: true` | `.prose/runs/{id}/agents/{name}/` | Dies with run |
| Project | `persist: project` | `.prose/agents/{name}/` | Survives runs in project |
| User | `persist: user` | `~/.prose/agents/{name}/` | Survives across projects |
| Custom | `persist: "path"` | Specified path | User-controlled |
---
## VM Update Protocol
After each statement completes, the VM:
1. **Confirms** subagent wrote its output file(s)
2. **Updates** `state.md` with new position and annotations
3. **Continues** to next statement
The VM never does compaction—that's the subagent's responsibility.
---
## Resuming Execution
If execution is interrupted, resume by:
1. Reading `.prose/runs/{id}/state.md` to find current position
2. Loading all bindings from `bindings/`
3. Continuing from the marked position
The `state.md` file contains everything needed to understand where execution stopped and what has been accomplished.

# In-Context State Management
This document describes how the OpenProse VM tracks execution state using **structured narration** in the conversation history. This is one of two state management approaches (the other being file-based state in `filesystem.md`).
## Overview
In-context state uses text-prefixed markers to persist state within the conversation. The VM "thinks aloud" about execution—what you say becomes what you remember.
**Key principle:** Your conversation history IS the VM's working memory.
---
## When to Use In-Context State
In-context state is appropriate for:
| Factor | In-Context | Use File-Based Instead |
|--------|------------|------------------------|
| Statement count | < 30 statements | >= 30 statements |
| Parallel branches | < 5 concurrent | >= 5 concurrent |
| Imported programs | 0-2 imports | >= 3 imports |
| Nested depth | <= 2 levels | > 2 levels |
| Expected duration | < 5 minutes | >= 5 minutes |
Announce your state mode at program start:
```
OpenProse Program Start
State mode: in-context (program is small, fits in context)
```
---
## The Narration Protocol
Use text-prefixed markers for each state change:
| Marker | Category | Usage |
|--------|----------|-------|
| [Program] | Program | Start, end, definition collection |
| [Position] | Position | Current statement being executed |
| [Binding] | Binding | Variable assignment or update |
| [Input] | Input | Receiving inputs from caller |
| [Output] | Output | Producing outputs for caller |
| [Import] | Import | Fetching and invoking imported programs |
| [Success] | Success | Session or block completion |
| [Warning] | Error | Failures and exceptions |
| [Parallel] | Parallel | Entering, branch status, joining |
| [Loop] | Loop | Iteration, condition evaluation |
| [Pipeline] | Pipeline | Stage progress |
| [Try] | Error handling | Try/catch/finally |
| [Flow] | Flow | Condition evaluation results |
| [Frame+] | Call Stack | Push new frame (block invocation) |
| [Frame-] | Call Stack | Pop frame (block completion) |
---
## Narration Patterns by Construct
### Session Statements
```
[Position] Executing: session "Research the topic"
[Task tool call]
[Success] Session complete: "Research found that..."
[Binding] let research = <result>
```
### Parallel Blocks
```
[Parallel] Entering parallel block (3 branches, strategy: all)
- security: pending
- perf: pending
- style: pending
[Multiple Task calls]
[Parallel] Parallel complete:
- security = "No vulnerabilities found..."
- perf = "Performance is acceptable..."
- style = "Code follows conventions..."
[Binding] security, perf, style bound
```
### Loop Blocks
```
[Loop] Starting loop until **task complete** (max: 5)
[Loop] Iteration 1 of max 5
[Position] session "Work on task"
[Success] Session complete
[Loop] Evaluating: **task complete**
[Flow] Not satisfied, continuing
[Loop] Iteration 2 of max 5
[Position] session "Work on task"
[Success] Session complete
[Loop] Evaluating: **task complete**
[Flow] Satisfied!
[Loop] Loop exited: condition satisfied at iteration 2
```
### Error Handling
```
[Try] Entering try block
[Position] session "Risky operation"
[Warning] Session failed: connection timeout
[Binding] err = {message: "connection timeout"}
[Try] Executing catch block
[Position] session "Handle error" with context: err
[Success] Recovery complete
[Try] Executing finally block
[Position] session "Cleanup"
[Success] Cleanup complete
```
### Variable Bindings
```
[Binding] let research = "AI safety research covers..." (mutable)
[Binding] const config = {model: "opus"} (immutable)
[Binding] research = "Updated research..." (reassignment, was: "AI safety...")
```
### Input/Output Bindings
```
[Input] Inputs received:
topic = "quantum computing" (from caller)
depth = "deep" (from caller)
[Output] output findings = "Research shows..." (will return to caller)
[Output] output sources = ["arxiv:2401.1234", ...] (will return to caller)
```
### Block Invocation and Call Stack
Track block invocations with frame markers:
```
[Position] do process(data, 5)
[Frame+] Entering block: process (execution_id: 1, depth: 1)
Arguments: chunk=data, depth=5
[Position] session "Split into parts"
[Task tool call]
[Success] Session complete
[Binding] let parts = <result> (execution_id: 1)
[Position] do process(parts[0], 4)
[Frame+] Entering block: process (execution_id: 2, depth: 2)
Arguments: chunk=parts[0], depth=4
Parent: execution_id 1
[Position] session "Split into parts"
[Task tool call]
[Success] Session complete
[Binding] let parts = <result> (execution_id: 2) # Shadows parent's 'parts'
... (continues recursively)
[Frame-] Exiting block: process (execution_id: 2)
[Position] session "Combine results"
[Task tool call]
[Success] Session complete
[Frame-] Exiting block: process (execution_id: 1)
```
**Key points:**
- Each `[Frame+]` must have a matching `[Frame-]`
- `execution_id` uniquely identifies each invocation
- `depth` shows call stack depth (1 = first level)
- Bindings include `(execution_id: N)` to indicate scope
- Nested frames show `Parent: execution_id N` for the scope chain
### Scoped Binding Narration
When inside a block invocation, always include the execution_id:
```
[Binding] let result = "computed value" (execution_id: 43)
```
For variable resolution across scopes:
```
[Binding] Resolving 'config': found in execution_id 41 (parent scope)
```
### Program Imports
```
[Import] Importing: @alice/research
Fetching from: https://p.prose.md/@alice/research
Inputs expected: [topic, depth]
Outputs provided: [findings, sources]
Registered as: research
[Import] Invoking: research(topic: "quantum computing")
[Input] Passing inputs:
topic = "quantum computing"
[... imported program execution ...]
[Output] Received outputs:
findings = "Quantum computing uses..."
sources = ["arxiv:2401.1234"]
[Import] Import complete: research
[Binding] result = { findings: "...", sources: [...] }
```
---
## Context Serialization
**In-context state passes values, not references.** This is the key difference from file-based and PostgreSQL state. The VM holds binding values directly in conversation history.
When passing context to sessions, format appropriately:
| Context Size | Strategy |
|--------------|----------|
| < 2000 chars | Pass verbatim |
| 2000-8000 chars | Summarize to key points |
| > 8000 chars | Extract essentials only |
**Format:**
```
Context provided:
---
research: "Key findings about AI safety..."
analysis: "Risk assessment shows..."
---
```
**Limitation:** In-context state cannot support RLM-style "environment as variable" patterns where agents query arbitrarily large bindings. For programs with large intermediate values, use file-based or PostgreSQL state instead.
---
## Complete Execution Trace Example
```prose
agent researcher:
model: sonnet
let research = session: researcher
prompt: "Research AI safety"
parallel:
a = session "Analyze risk A"
b = session "Analyze risk B"
loop until **analysis complete** (max: 3):
session "Synthesize"
context: { a, b, research }
```
**Narration:**
```
[Program] Program Start
Collecting definitions...
- Agent: researcher (model: sonnet)
[Position] Statement 1: let research = session: researcher
Spawning with prompt: "Research AI safety"
Model: sonnet
[Task tool call]
[Success] Session complete: "AI safety research covers alignment..."
[Binding] let research = <result>
[Position] Statement 2: parallel block
[Parallel] Entering parallel (2 branches, strategy: all)
[Task: "Analyze risk A"] [Task: "Analyze risk B"]
[Parallel] Parallel complete:
- a = "Risk A: potential misalignment..."
- b = "Risk B: robustness concerns..."
[Binding] a, b bound
[Position] Statement 3: loop until **analysis complete** (max: 3)
[Loop] Starting loop
[Loop] Iteration 1 of max 3
[Position] session "Synthesize" with context: {a, b, research}
[Task with serialized context]
[Success] Result: "Initial synthesis shows..."
[Loop] Evaluating: **analysis complete**
[Flow] Not satisfied (synthesis is preliminary)
[Loop] Iteration 2 of max 3
[Position] session "Synthesize" with context: {a, b, research}
[Task with serialized context]
[Success] Result: "Comprehensive analysis complete..."
[Loop] Evaluating: **analysis complete**
[Flow] Satisfied!
[Loop] Loop exited: condition satisfied at iteration 2
[Program] Program Complete
```
---
## State Categories
The VM must track these state categories in narration:
| Category | What to Track | Example |
|----------|---------------|---------|
| **Import Registry** | Imported programs and aliases | `research: @alice/research` |
| **Agent Registry** | All agent definitions | `researcher: {model: sonnet, prompt: "..."}` |
| **Block Registry** | All block definitions (hoisted) | `review: {params: [topic], body: [...]}` |
| **Input Bindings** | Inputs received from caller | `topic = "quantum computing"` |
| **Output Bindings** | Outputs to return to caller | `findings = "Research shows..."` |
| **Variable Bindings** | Name -> value mapping (with execution_id) | `result = "..." (execution_id: 3)` |
| **Variable Mutability** | Which are `let` vs `const` vs `output` | `research: let, findings: output` |
| **Execution Position** | Current statement index | Statement 3 of 7 |
| **Loop State** | Counter, max, condition | Iteration 2 of max 5 |
| **Parallel State** | Branches, results, strategy | `{a: complete, b: pending}` |
| **Error State** | Exception, retry count | Retry 2 of 3, error: "timeout" |
| **Call Stack** | Stack of execution frames | See below |
### Call Stack State
For block invocations, track the full call stack:
```
[CallStack] Current stack (depth: 3):
execution_id: 5 | block: process | depth: 3 | status: executing
execution_id: 3 | block: process | depth: 2 | status: waiting
execution_id: 1 | block: process | depth: 1 | status: waiting
```
Each frame tracks:
- `execution_id`: Unique ID for this invocation
- `block`: Name of the block
- `depth`: Position in call stack
- `status`: executing, waiting, or completed
---
## Independence from File-Based State
In-context state and file-based state (`filesystem.md`) are **independent approaches**. You choose one or the other based on program complexity.
- **In-context**: State lives in conversation history
- **File-based**: State lives in `.prose/runs/{id}/`
They are not designed to be complementary—pick the appropriate mode at program start.
---
## Summary
In-context state management:
1. Uses **text-prefixed markers** to track state changes
2. Persists state in **conversation history**
3. Is appropriate for **smaller, simpler programs**
4. Requires **consistent narration** throughout execution
5. Makes state **visible** in the conversation itself
The narration protocol ensures that the VM can recover its execution state by reading its own prior messages. What you say becomes what you remember.

role: postgres-state-management
status: experimental
summary: |
PostgreSQL-based state management for OpenProse programs. This approach persists
execution state to a PostgreSQL database, enabling true concurrent writes,
network access, team collaboration, and high-throughput workloads.
requires: psql CLI tool in PATH, running PostgreSQL server
see-also:
- ../prose.md: VM execution semantics
- filesystem.md: File-based state (default, simpler)
- sqlite.md: SQLite state (queryable, single-file)
- in-context.md: In-context state (for simple programs)

# PostgreSQL State Management (Experimental)
This document describes how the OpenProse VM tracks execution state using a **PostgreSQL database**. This is an experimental alternative to file-based state (`filesystem.md`), SQLite state (`sqlite.md`), and in-context state (`in-context.md`).
## Prerequisites
**Requires:**
1. The `psql` command-line tool must be available in your PATH
2. A running PostgreSQL server (local, Docker, or cloud)
### Installing psql
| Platform | Command | Notes |
|----------|---------|-------|
| macOS (Homebrew) | `brew install libpq && brew link --force libpq` | Client-only; no server |
| macOS (Postgres.app) | Download from https://postgresapp.com | Full install with GUI |
| Debian/Ubuntu | `apt install postgresql-client` | Client-only |
| Fedora/RHEL | `dnf install postgresql` | Client-only |
| Arch Linux | `pacman -S postgresql-libs` | Client-only |
| Windows | `winget install PostgreSQL.PostgreSQL` | Full installer |
After installation, verify:
```bash
psql --version # Should output: psql (PostgreSQL) 16.x
```
If `psql` is not available, the VM will offer to fall back to SQLite state.
---
## Overview
PostgreSQL state provides:
- **True concurrent writes**: Row-level locking allows parallel branches to write simultaneously
- **Network access**: Query state from any machine, external tools, or dashboards
- **Team collaboration**: Multiple developers can share run state
- **Rich SQL**: JSONB queries, window functions, CTEs for complex state analysis
- **High throughput**: Handle 1000+ writes/minute, multi-GB outputs
- **Durability**: WAL-based recovery, point-in-time restore
**Key principle:** The database is a flexible, shared workspace. The VM and subagents coordinate through it, and external tools can observe and query execution state in real-time.
---
## Security Warning
**⚠️ Credentials are visible to subagents.** The `OPENPROSE_POSTGRES_URL` connection string is passed to spawned sessions so they can write their outputs. This means:
- Database credentials appear in subagent context and may be logged
- Treat these credentials as **non-sensitive**
- Use a **dedicated database** for OpenProse, not your production systems
- Create a **limited-privilege user** with access only to the `openprose` schema
**Recommended setup:**
```sql
-- Create dedicated user with minimal privileges
CREATE USER openprose_agent WITH PASSWORD 'changeme';
CREATE SCHEMA openprose AUTHORIZATION openprose_agent;
GRANT ALL ON SCHEMA openprose TO openprose_agent;
-- User can only access the openprose schema, nothing else
```
---
## When to Use PostgreSQL State
PostgreSQL state is for **power users** with specific scale or collaboration needs:
| Need | PostgreSQL Helps |
|------|------------------|
| >5 parallel branches writing simultaneously | SQLite locks; PostgreSQL doesn't |
| External dashboards querying state | PostgreSQL is designed for concurrent readers |
| Team collaboration on long workflows | Shared network access; no file sync needed |
| Outputs exceeding 1GB | Bulk ingestion; no single-file bottleneck |
| Mission-critical workflows (hours/days) | Robust durability; point-in-time recovery |
**If none of these apply, use filesystem or SQLite state.** They're simpler and sufficient for 99% of programs.
### Decision Tree
```
Is your program <30 statements with no parallel blocks?
YES -> Use in-context state (zero friction)
NO -> Continue...
Do external tools (dashboards, monitoring, analytics) need to query state?
YES -> Use PostgreSQL (network access required)
NO -> Continue...
Do multiple machines or team members need shared access to the same run?
YES -> Use PostgreSQL (collaboration)
NO -> Continue...
Do you have >5 concurrent parallel branches writing simultaneously?
YES -> Use PostgreSQL (concurrency)
NO -> Continue...
Will outputs exceed 1GB or writes exceed 100/minute?
YES -> Use PostgreSQL (scale)
NO -> Use filesystem (default) or SQLite (if you want SQL queries)
```
### The Concurrency Case
The primary motivation for PostgreSQL is **concurrent writes in parallel execution**:
- SQLite uses table-level locks: parallel branches serialize
- PostgreSQL uses row-level locks: parallel branches write simultaneously
If your program has 10 parallel branches completing at once, PostgreSQL will be 5-10x faster than SQLite for the write phase.
---
## Database Setup
### Option 1: Docker (Recommended)
The fastest path to a running PostgreSQL instance:
```bash
docker run -d \
--name prose-pg \
-e POSTGRES_DB=prose \
-e POSTGRES_HOST_AUTH_METHOD=trust \
-p 5432:5432 \
postgres:16
```
Then configure the connection:
```bash
mkdir -p .prose
echo "OPENPROSE_POSTGRES_URL=postgresql://postgres@localhost:5432/prose" > .prose/.env
```
Management commands:
```bash
docker ps | grep prose-pg # Check if running
docker logs prose-pg # View logs
docker stop prose-pg # Stop
docker start prose-pg # Start again
docker rm -f prose-pg # Remove completely
```
### Option 2: Local PostgreSQL
For users who prefer native PostgreSQL:
**macOS (Homebrew):**
```bash
brew install postgresql@16
brew services start postgresql@16
createdb myproject
echo "OPENPROSE_POSTGRES_URL=postgresql://localhost/myproject" >> .prose/.env
```
**Linux (Debian/Ubuntu):**
```bash
sudo apt install postgresql
sudo systemctl start postgresql
sudo -u postgres createdb myproject
echo "OPENPROSE_POSTGRES_URL=postgresql:///myproject" >> .prose/.env
```
### Option 3: Cloud PostgreSQL
For team collaboration or production:
| Provider | Free Tier | Cold Start | Best For |
|----------|-----------|------------|----------|
| **Neon** | 0.5GB, auto-suspend | 1-3s | Development, testing |
| **Supabase** | 500MB, no auto-suspend | None | Projects needing auth/storage |
| **Railway** | $5/mo credit | None | Simple production deploys |
```bash
# Example: Neon
echo "OPENPROSE_POSTGRES_URL=postgresql://user:pass@ep-name.us-east-2.aws.neon.tech/neondb?sslmode=require" >> .prose/.env
```
---
## Database Location
The connection string is stored in `.prose/.env`:
```
your-project/
├── .prose/
│ ├── .env # OPENPROSE_POSTGRES_URL=...
│ └── runs/ # Execution metadata and attachments
│ └── {YYYYMMDD}-{HHMMSS}-{random}/
│ ├── program.prose # Copy of running program
│ └── attachments/ # Large outputs (optional)
├── .gitignore # Should exclude .prose/.env
└── your-program.prose
```
**Run ID format:** `{YYYYMMDD}-{HHMMSS}-{random6}`
Example: `20260116-143052-a7b3c9`
### Environment Variable Precedence
The VM checks in this order:
1. `OPENPROSE_POSTGRES_URL` in `.prose/.env`
2. `OPENPROSE_POSTGRES_URL` in shell environment
3. `DATABASE_URL` in shell environment (common fallback)
### Security: Add to .gitignore
```gitignore
# OpenProse sensitive files
.prose/.env
.prose/runs/
```
---
## Responsibility Separation
This section defines **who does what**. This is the contract between the VM and subagents.
### VM Responsibilities
The VM (the orchestrating agent running the .prose program) is responsible for:
| Responsibility | Description |
|----------------|-------------|
| **Schema initialization** | Create `openprose` schema and tables at run start |
| **Run registration** | Store the program source and metadata |
| **Execution tracking** | Update position, status, and timing as statements execute |
| **Subagent spawning** | Spawn sessions via Task tool with database instructions |
| **Parallel coordination** | Track branch status, implement join strategies |
| **Loop management** | Track iteration counts, evaluate conditions |
| **Error aggregation** | Record failures, manage retry state |
| **Context preservation** | Maintain sufficient narration in the main thread |
| **Completion detection** | Mark the run as complete when finished |
**Critical:** The VM must preserve enough context in its own conversation to understand execution state without re-reading the entire database. The database is for coordination and persistence, not a replacement for working memory.
### Subagent Responsibilities
Subagents (sessions spawned by the VM) are responsible for:
| Responsibility | Description |
|----------------|-------------|
| **Writing own outputs** | Insert/update their binding in the `bindings` table |
| **Memory management** | For persistent agents: read and update their memory record |
| **Segment recording** | For persistent agents: append segment history |
| **Attachment handling** | Write large outputs to `attachments/` directory, store path in DB |
| **Atomic writes** | Use transactions when updating multiple related records |
**Critical:** Subagents write ONLY to `bindings`, `agents`, and `agent_segments` tables. The VM owns the `execution` table entirely. Completion signaling happens through the substrate (Task tool return), not database updates.
**Critical:** Subagents must write their outputs directly to the database. The VM does not write subagent outputs—it only reads them after the subagent completes.
**What subagents return to the VM:** A confirmation message with the binding location—not the full content:
**Root scope:**
```
Binding written: research
Location: openprose.bindings WHERE name='research' AND run_id='20260116-143052-a7b3c9' AND execution_id IS NULL
Summary: AI safety research covering alignment, robustness, and interpretability with 15 citations.
```
**Inside block invocation:**
```
Binding written: result
Location: openprose.bindings WHERE name='result' AND run_id='20260116-143052-a7b3c9' AND execution_id=43
Execution ID: 43
Summary: Processed chunk into 3 sub-parts for recursive processing.
```
The VM tracks locations, not values. This keeps the VM's context lean and enables arbitrarily large intermediate values.
### Shared Concerns
| Concern | Who Handles |
|---------|-------------|
| Schema evolution | Either (use `CREATE TABLE IF NOT EXISTS`, `ALTER TABLE` as needed) |
| Custom tables | Either (prefix with `x_` for extensions) |
| Indexing | Either (add indexes for frequently-queried columns) |
| Cleanup | VM (at run end, optionally delete old data) |
---
## Core Schema
The VM initializes these tables using the `openprose` schema. This is a **minimum viable schema**—extend freely.
```sql
-- Create dedicated schema for OpenProse state
CREATE SCHEMA IF NOT EXISTS openprose;
-- Run metadata
CREATE TABLE IF NOT EXISTS openprose.run (
id TEXT PRIMARY KEY,
program_path TEXT,
program_source TEXT,
started_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
updated_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
status TEXT NOT NULL DEFAULT 'running'
CHECK (status IN ('running', 'completed', 'failed', 'interrupted')),
state_mode TEXT NOT NULL DEFAULT 'postgres',
metadata JSONB DEFAULT '{}'::jsonb
);
-- Execution position and history
CREATE TABLE IF NOT EXISTS openprose.execution (
id SERIAL PRIMARY KEY,
run_id TEXT NOT NULL REFERENCES openprose.run(id) ON DELETE CASCADE,
statement_index INTEGER NOT NULL,
statement_text TEXT,
status TEXT NOT NULL DEFAULT 'pending'
CHECK (status IN ('pending', 'executing', 'completed', 'failed', 'skipped')),
started_at TIMESTAMPTZ,
completed_at TIMESTAMPTZ,
error_message TEXT,
parent_id INTEGER REFERENCES openprose.execution(id) ON DELETE CASCADE,
metadata JSONB DEFAULT '{}'::jsonb
);
-- All named values (input, output, let, const)
CREATE TABLE IF NOT EXISTS openprose.bindings (
name TEXT NOT NULL,
run_id TEXT NOT NULL REFERENCES openprose.run(id) ON DELETE CASCADE,
execution_id INTEGER, -- NULL for root scope, non-null for block invocations
kind TEXT NOT NULL CHECK (kind IN ('input', 'output', 'let', 'const')),
value TEXT,
source_statement TEXT,
created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
updated_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
attachment_path TEXT,
metadata JSONB DEFAULT '{}'::jsonb,
PRIMARY KEY (name, run_id, COALESCE(execution_id, -1)) -- Composite key with scope
);
-- Persistent agent memory
CREATE TABLE IF NOT EXISTS openprose.agents (
name TEXT NOT NULL,
run_id TEXT, -- NULL for project-scoped and user-scoped agents
scope TEXT NOT NULL CHECK (scope IN ('execution', 'project', 'user', 'custom')),
memory TEXT,
created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
updated_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
metadata JSONB DEFAULT '{}'::jsonb,
PRIMARY KEY (name, COALESCE(run_id, '__project__'))
);
-- Agent invocation history
CREATE TABLE IF NOT EXISTS openprose.agent_segments (
id SERIAL PRIMARY KEY,
agent_name TEXT NOT NULL,
run_id TEXT, -- NULL for project-scoped agents
segment_number INTEGER NOT NULL,
timestamp TIMESTAMPTZ NOT NULL DEFAULT NOW(),
prompt TEXT,
summary TEXT,
metadata JSONB DEFAULT '{}'::jsonb,
UNIQUE (agent_name, COALESCE(run_id, '__project__'), segment_number)
);
-- Import registry
CREATE TABLE IF NOT EXISTS openprose.imports (
alias TEXT NOT NULL,
run_id TEXT NOT NULL REFERENCES openprose.run(id) ON DELETE CASCADE,
source_url TEXT NOT NULL,
fetched_at TIMESTAMPTZ,
inputs_schema JSONB,
outputs_schema JSONB,
content_hash TEXT,
metadata JSONB DEFAULT '{}'::jsonb,
PRIMARY KEY (alias, run_id)
);
-- Indexes for common queries
CREATE INDEX IF NOT EXISTS idx_execution_run_id ON openprose.execution(run_id);
CREATE INDEX IF NOT EXISTS idx_execution_status ON openprose.execution(status);
CREATE INDEX IF NOT EXISTS idx_execution_parent_id ON openprose.execution(parent_id) WHERE parent_id IS NOT NULL;
CREATE INDEX IF NOT EXISTS idx_execution_metadata_gin ON openprose.execution USING GIN (metadata jsonb_path_ops);
CREATE INDEX IF NOT EXISTS idx_bindings_run_id ON openprose.bindings(run_id);
CREATE INDEX IF NOT EXISTS idx_bindings_execution_id ON openprose.bindings(execution_id) WHERE execution_id IS NOT NULL;
CREATE INDEX IF NOT EXISTS idx_agents_run_id ON openprose.agents(run_id) WHERE run_id IS NOT NULL;
CREATE INDEX IF NOT EXISTS idx_agents_project_scoped ON openprose.agents(name) WHERE run_id IS NULL;
CREATE INDEX IF NOT EXISTS idx_agent_segments_lookup ON openprose.agent_segments(agent_name, run_id);
```
### Schema Conventions
- **Timestamps**: Use `TIMESTAMPTZ` with `NOW()` (timezone-aware)
- **JSON fields**: Use `JSONB` for structured data in `metadata` columns (queryable, indexable)
- **Large values**: If a binding value exceeds ~100KB, write to `attachments/{name}.md` and store path
- **Extension tables**: Prefix with `x_` (e.g., `x_metrics`, `x_audit_log`)
- **Anonymous bindings**: Sessions without explicit capture use auto-generated names: `anon_001`, `anon_002`, etc.
- **Import bindings**: Prefix with import alias for scoping: `research.findings`, `research.sources`
- **Scoped bindings**: Use `execution_id` column—NULL for root scope, non-null for block invocations
### Scope Resolution Query
For recursive blocks, bindings are scoped to their execution frame. Resolve variables by walking up the call stack:
```sql
-- Find binding 'result' starting from execution_id 43 in run '20260116-143052-a7b3c9'
WITH RECURSIVE scope_chain AS (
-- Start with current execution
SELECT id, parent_id FROM openprose.execution WHERE id = 43
UNION ALL
-- Walk up to parent
SELECT e.id, e.parent_id
FROM openprose.execution e
JOIN scope_chain s ON e.id = s.parent_id
)
SELECT b.* FROM openprose.bindings b
WHERE b.name = 'result'
AND b.run_id = '20260116-143052-a7b3c9'
AND (b.execution_id IN (SELECT id FROM scope_chain) OR b.execution_id IS NULL)
ORDER BY
CASE WHEN b.execution_id IS NULL THEN 1 ELSE 0 END, -- Prefer scoped over root
b.execution_id DESC NULLS LAST -- Prefer deeper (more local) scope
LIMIT 1;
```
**Simpler version if you know the scope chain:**
```sql
-- Direct lookup: check current scope (43), then parent (42), then root (NULL)
SELECT * FROM openprose.bindings
WHERE name = 'result'
AND run_id = '20260116-143052-a7b3c9'
AND (execution_id = 43 OR execution_id = 42 OR execution_id IS NULL)
ORDER BY execution_id DESC NULLS LAST
LIMIT 1;
```

## Database Interaction
Both VM and subagents interact via the `psql` CLI.
### From the VM
```bash
# Initialize schema
psql "$OPENPROSE_POSTGRES_URL" -f schema.sql
# Register a new run
psql "$OPENPROSE_POSTGRES_URL" -c "
INSERT INTO openprose.run (id, program_path, program_source, status)
VALUES ('20260116-143052-a7b3c9', '/path/to/program.prose', 'program source...', 'running')
"
# Update execution position
psql "$OPENPROSE_POSTGRES_URL" -c "
INSERT INTO openprose.execution (run_id, statement_index, statement_text, status, started_at)
VALUES ('20260116-143052-a7b3c9', 3, 'session \"Research AI safety\"', 'executing', NOW())
"
# Read a binding
psql "$OPENPROSE_POSTGRES_URL" -t -A -c "
SELECT value FROM openprose.bindings WHERE name = 'research' AND run_id = '20260116-143052-a7b3c9'
"
# Check parallel branch status
psql "$OPENPROSE_POSTGRES_URL" -c "
SELECT metadata->>'branch' AS branch, status FROM openprose.execution
WHERE run_id = '20260116-143052-a7b3c9' AND metadata->>'parallel_id' = 'p1'
"
```
### From Subagents
The VM provides the database path and instructions when spawning:
**Root scope (outside block invocations):**
```
Your output goes to PostgreSQL state.
| Property | Value |
|----------|-------|
| Connection | `postgresql://user:***@host:5432/db` |
| Schema | `openprose` |
| Run ID | `20260116-143052-a7b3c9` |
| Binding | `research` |
| Execution ID | (root scope) |
When complete, write your output:
psql "$OPENPROSE_POSTGRES_URL" -c "
INSERT INTO openprose.bindings (name, run_id, execution_id, kind, value, source_statement)
VALUES (
'research',
'20260116-143052-a7b3c9',
NULL, -- root scope
'let',
E'AI safety research covers alignment, robustness...',
'let research = session: researcher'
)
ON CONFLICT (name, run_id, COALESCE(execution_id, -1)) DO UPDATE
SET value = EXCLUDED.value, updated_at = NOW()
"
```
**Inside block invocation (include execution_id):**
```
Your output goes to PostgreSQL state.
| Property | Value |
|----------|-------|
| Connection | `postgresql://user:***@host:5432/db` |
| Schema | `openprose` |
| Run ID | `20260116-143052-a7b3c9` |
| Binding | `result` |
| Execution ID | `43` |
| Block | `process` |
| Depth | `3` |
When complete, write your output:
psql "$OPENPROSE_POSTGRES_URL" -c "
INSERT INTO openprose.bindings (name, run_id, execution_id, kind, value, source_statement)
VALUES (
'result',
'20260116-143052-a7b3c9',
43, -- scoped to this execution
'let',
E'Processed chunk into 3 sub-parts...',
'let result = session \"Process chunk\"'
)
ON CONFLICT (name, run_id, COALESCE(execution_id, -1)) DO UPDATE
SET value = EXCLUDED.value, updated_at = NOW()
"
```
For persistent agents (execution-scoped):
```
Your memory is in the database:
Read your current state:
psql "$OPENPROSE_POSTGRES_URL" -t -A -c "SELECT memory FROM openprose.agents WHERE name = 'captain' AND run_id = '20260116-143052-a7b3c9'"
Update when done:
psql "$OPENPROSE_POSTGRES_URL" -c "UPDATE openprose.agents SET memory = '...', updated_at = NOW() WHERE name = 'captain' AND run_id = '20260116-143052-a7b3c9'"
Record this segment:
psql "$OPENPROSE_POSTGRES_URL" -c "INSERT INTO openprose.agent_segments (agent_name, run_id, segment_number, prompt, summary) VALUES ('captain', '20260116-143052-a7b3c9', 3, '...', '...')"
```
For project-scoped agents, use `run_id IS NULL` in queries:
```sql
-- Read project-scoped agent memory
SELECT memory FROM openprose.agents WHERE name = 'advisor' AND run_id IS NULL;
-- Update project-scoped agent memory
UPDATE openprose.agents SET memory = '...' WHERE name = 'advisor' AND run_id IS NULL;
```
---
## Context Preservation in Main Thread
**This is critical.** The database is for persistence and coordination, but the VM must still maintain conversational context.
### What the VM Must Narrate
Even with PostgreSQL state, the VM should narrate key events in its conversation:
```
[Position] Statement 3: let research = session: researcher
Spawning session, will write to state database
[Task tool call]
[Success] Session complete, binding written to DB
[Binding] research = <stored in openprose.bindings>
```
### Why Both?
| Purpose | Mechanism |
|---------|-----------|
| **Working memory** | Conversation narration (what the VM "remembers" without re-querying) |
| **Durable state** | PostgreSQL database (survives context limits, enables resumption) |
| **Subagent coordination** | PostgreSQL database (shared access point) |
| **Debugging/inspection** | PostgreSQL database (queryable history) |
The narration is the VM's "mental model" of execution. The database is the "source of truth" for resumption and inspection.
---
## Parallel Execution
For parallel blocks, the VM uses the `metadata` JSONB field to track branches. **Only the VM writes to the `execution` table.**
```sql
-- VM marks parallel start
INSERT INTO openprose.execution (run_id, statement_index, statement_text, status, started_at, metadata)
VALUES ('20260116-143052-a7b3c9', 5, 'parallel:', 'executing', NOW(),
'{"parallel_id": "p1", "strategy": "all", "branches": ["a", "b", "c"]}'::jsonb)
RETURNING id; -- Save as parent_id (e.g., 42)
-- VM creates execution record for each branch
INSERT INTO openprose.execution (run_id, statement_index, statement_text, status, started_at, parent_id, metadata)
VALUES
('20260116-143052-a7b3c9', 6, 'a = session "Task A"', 'executing', NOW(), 42, '{"parallel_id": "p1", "branch": "a"}'::jsonb),
('20260116-143052-a7b3c9', 7, 'b = session "Task B"', 'executing', NOW(), 42, '{"parallel_id": "p1", "branch": "b"}'::jsonb),
('20260116-143052-a7b3c9', 8, 'c = session "Task C"', 'executing', NOW(), 42, '{"parallel_id": "p1", "branch": "c"}'::jsonb);
-- Subagents write their outputs to bindings table (see "From Subagents" section)
-- Task tool signals completion to VM via substrate
-- VM marks branch complete after Task returns
UPDATE openprose.execution SET status = 'completed', completed_at = NOW()
WHERE run_id = '20260116-143052-a7b3c9' AND metadata->>'parallel_id' = 'p1' AND metadata->>'branch' = 'a';
-- VM checks if all branches complete
SELECT COUNT(*) AS pending FROM openprose.execution
WHERE run_id = '20260116-143052-a7b3c9'
AND metadata->>'parallel_id' = 'p1'
AND parent_id IS NOT NULL
AND status NOT IN ('completed', 'failed', 'skipped');
```
### The Concurrency Advantage
Each subagent writes to a different row in `openprose.bindings`. PostgreSQL's row-level locking means **no blocking**:
```
SQLite (table locks):
Branch 1 writes -------|
Branch 2 waits ------|
Branch 3 waits -----|
Total time: 3 * write_time (serialized)
PostgreSQL (row locks):
Branch 1 writes --|
Branch 2 writes --| (concurrent)
Branch 3 writes --|
Total time: ~1 * write_time (parallel)
```
---
## Loop Tracking
```sql
-- Loop metadata tracks iteration state
INSERT INTO openprose.execution (run_id, statement_index, statement_text, status, started_at, metadata)
VALUES ('20260116-143052-a7b3c9', 10, 'loop until **analysis complete** (max: 5):', 'executing', NOW(),
'{"loop_id": "l1", "max_iterations": 5, "current_iteration": 0, "condition": "**analysis complete**"}'::jsonb);
-- Update iteration
UPDATE openprose.execution
SET metadata = jsonb_set(metadata, '{current_iteration}', '2')
WHERE run_id = '20260116-143052-a7b3c9' AND metadata->>'loop_id' = 'l1' AND parent_id IS NULL;
```
---
## Error Handling
```sql
-- Record failure
UPDATE openprose.execution
SET status = 'failed',
error_message = 'Connection timeout after 30s',
completed_at = NOW()
WHERE id = 15;
-- Track retry attempts in metadata
UPDATE openprose.execution
SET metadata = jsonb_set(jsonb_set(metadata, '{retry_attempt}', '2'), '{max_retries}', '3')
WHERE id = 15;
-- Mark run as failed
UPDATE openprose.run SET status = 'failed' WHERE id = '20260116-143052-a7b3c9';
```
---
## Project-Scoped and User-Scoped Agents
Execution-scoped agents (the default) use `run_id = specific value`. **Project-scoped agents** (`persist: project`) and **user-scoped agents** (`persist: user`) use `run_id IS NULL` and survive across runs.
For user-scoped agents, the VM maintains a separate connection or uses a naming convention to distinguish them from project-scoped agents. One approach is to prefix user-scoped agent names with `__user__` in the same database, or use a separate user-level database configured via `OPENPROSE_POSTGRES_USER_URL`.
### The run_id Approach
The `COALESCE` trick in the primary key allows both scopes in one table:
```sql
PRIMARY KEY (name, COALESCE(run_id, '__project__'))
```
This means:
- `name='advisor', run_id=NULL` has PK `('advisor', '__project__')`
- `name='advisor', run_id='20260116-143052-a7b3c9'` has PK `('advisor', '20260116-143052-a7b3c9')`
The same agent name can exist as both project-scoped and execution-scoped without collision.
### Query Patterns
| Scope | Query |
|-------|-------|
| Execution-scoped | `WHERE name = 'captain' AND run_id = '{RUN_ID}'` |
| Project-scoped | `WHERE name = 'advisor' AND run_id IS NULL` |
### Project-Scoped Memory Guidelines
Project-scoped agents should store generalizable knowledge that accumulates:
**DO store:** User preferences, project context, learned patterns, decision rationale
**DO NOT store:** Run-specific details, time-sensitive information, large data
### Agent Cleanup
- **Execution-scoped:** Can be deleted when run completes or after retention period
- **Project-scoped:** Only deleted on explicit user request
```sql
-- Delete execution-scoped agents for a completed run
DELETE FROM openprose.agents WHERE run_id = '20260116-143052-a7b3c9';
-- Delete a specific project-scoped agent (user-initiated)
DELETE FROM openprose.agents WHERE name = 'old_advisor' AND run_id IS NULL;
```
---
## Large Outputs
When a binding value is too large for comfortable database storage (>100KB):
1. Write content to `attachments/{binding_name}.md`
2. Store the path in the `attachment_path` column
3. Leave `value` as a summary
```sql
INSERT INTO openprose.bindings (name, run_id, kind, value, attachment_path, source_statement)
VALUES (
'full_report',
'20260116-143052-a7b3c9',
'let',
'Full analysis report (847KB) - see attachment',
'attachments/full_report.md',
'let full_report = session "Generate comprehensive report"'
)
ON CONFLICT (name, run_id) DO UPDATE
SET value = EXCLUDED.value, attachment_path = EXCLUDED.attachment_path, updated_at = NOW();
```
---
## Resuming Execution
To resume an interrupted run:
```sql
-- Find current position
SELECT statement_index, statement_text, status
FROM openprose.execution
WHERE run_id = '20260116-143052-a7b3c9' AND status = 'executing'
ORDER BY id DESC LIMIT 1;
-- Get all completed bindings
SELECT name, kind, value, attachment_path FROM openprose.bindings
WHERE run_id = '20260116-143052-a7b3c9';
-- Get agent memory states
SELECT name, scope, memory FROM openprose.agents
WHERE run_id = '20260116-143052-a7b3c9' OR run_id IS NULL;
-- Check parallel block status
SELECT metadata->>'branch' AS branch, status
FROM openprose.execution
WHERE run_id = '20260116-143052-a7b3c9'
AND metadata->>'parallel_id' IS NOT NULL
AND parent_id IS NOT NULL;
```
---
## Flexibility Encouragement
PostgreSQL state is intentionally **flexible**. The core schema is a starting point. You are encouraged to:
- **Add columns** to existing tables as needed
- **Create extension tables** (prefix with `x_`)
- **Store custom metrics** (timing, token counts, model info)
- **Build indexes** for your query patterns
- **Use JSONB operators** for semi-structured data queries
Example extensions:
```sql
-- Custom metrics table
CREATE TABLE IF NOT EXISTS openprose.x_metrics (
id SERIAL PRIMARY KEY,
run_id TEXT REFERENCES openprose.run(id) ON DELETE CASCADE,
execution_id INTEGER REFERENCES openprose.execution(id) ON DELETE CASCADE,
metric_name TEXT NOT NULL,
metric_value NUMERIC,
recorded_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
metadata JSONB DEFAULT '{}'::jsonb
);
-- Add custom column
ALTER TABLE openprose.bindings ADD COLUMN IF NOT EXISTS token_count INTEGER;
-- Create index for common query
CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_bindings_created ON openprose.bindings(created_at);
```
The database is your workspace. Use it.

---
## Summary
PostgreSQL state management:
1. Uses a **shared PostgreSQL database** for all runs
2. Provides **true concurrent writes** via row-level locking
3. Enables **network access** for external tools and dashboards
4. Supports **team collaboration** on shared run state
5. Allows **flexible schema evolution** with JSONB and custom tables
6. Requires the **psql CLI** and a running PostgreSQL server
7. Is **experimental**—expect changes
The core contract: the VM manages execution flow and spawns subagents; subagents write their own outputs directly to the database. Completion is signaled through the Task tool return, not database updates. External tools can query execution state in real-time.
**PostgreSQL state is for power users.** If you don't need concurrent writes, network access, or team collaboration, filesystem or SQLite state will be simpler and sufficient.

role: sqlite-state-management
status: experimental
summary: |
SQLite-based state management for OpenProse programs. This approach persists
execution state to a SQLite database, enabling structured queries, atomic
transactions, and flexible schema evolution.
requires: sqlite3 CLI tool in PATH
see-also:
- ../prose.md: VM execution semantics

# SQLite State Management (Experimental)
This document describes how the OpenProse VM tracks execution state using a **SQLite database**. This is an experimental alternative to file-based state (`filesystem.md`) and in-context state (`in-context.md`).
## Prerequisites
**Requires:** The `sqlite3` command-line tool must be available in your PATH.
| Platform | Installation |
|----------|--------------|
| macOS | Pre-installed |
| Linux | `apt install sqlite3` / `dnf install sqlite3` / etc. |
| Windows | `winget install SQLite.SQLite` or download from sqlite.org |
If `sqlite3` is not available, the VM will fall back to filesystem state and warn the user.
---
## Overview
SQLite state provides:
- **Atomic transactions**: State changes are ACID-compliant
- **Structured queries**: Find specific bindings, filter by status, aggregate results
- **Flexible schema**: Add columns and tables as needed
- **Single-file portability**: The entire run state is one `.db` file
- **Concurrent access**: SQLite handles locking automatically
**Key principle:** The database is a flexible workspace. The VM and subagents share it as a coordination mechanism, not a rigid contract.
---
## Database Location
The database lives within the standard run directory:
```
.prose/runs/{YYYYMMDD}-{HHMMSS}-{random}/
├── state.db # SQLite database (this file)
├── program.prose # Copy of running program
└── attachments/ # Large outputs that don't fit in DB (optional)
```
**Run ID format:** Same as filesystem state: `{YYYYMMDD}-{HHMMSS}-{random6}`
Example: `.prose/runs/20260116-143052-a7b3c9/state.db`
### Project-Scoped and User-Scoped Agents
Execution-scoped agents (the default) live in the per-run `state.db`. However, **project-scoped agents** (`persist: project`) and **user-scoped agents** (`persist: user`) must survive across runs.
For project-scoped agents, use a separate database:
```
.prose/
├── agents.db # Project-scoped agent memory (survives runs)
└── runs/
└── {id}/
└── state.db # Execution-scoped state (dies with run)
```
For user-scoped agents, use a database in the home directory:
```
~/.prose/
└── agents.db # User-scoped agent memory (survives across projects)
```
The `agents` and `agent_segments` tables for project-scoped agents live in `.prose/agents.db`, and for user-scoped agents live in `~/.prose/agents.db`. The VM initializes these databases on first use and provides the correct path to subagents.
---
## Responsibility Separation
This section defines **who does what**. This is the contract between the VM and subagents.
### VM Responsibilities
The VM (the orchestrating agent running the .prose program) is responsible for:
| Responsibility | Description |
|----------------|-------------|
| **Database creation** | Create `state.db` and initialize core tables at run start |
| **Program registration** | Store the program source and metadata |
| **Execution tracking** | Update position, status, and timing as statements execute |
| **Subagent spawning** | Spawn sessions via Task tool with database path and instructions |
| **Parallel coordination** | Track branch status, implement join strategies |
| **Loop management** | Track iteration counts, evaluate conditions |
| **Error aggregation** | Record failures, manage retry state |
| **Context preservation** | Maintain sufficient narration in the main conversation thread so execution can be understood and resumed |
| **Completion detection** | Mark the run as complete when finished |
**Critical:** The VM must preserve enough context in its own conversation to understand execution state without re-reading the entire database. The database is for coordination and persistence, not a replacement for working memory.
### Subagent Responsibilities
Subagents (sessions spawned by the VM) are responsible for:
| Responsibility | Description |
|----------------|-------------|
| **Writing own outputs** | Insert/update their binding in the `bindings` table |
| **Memory management** | For persistent agents: read and update their memory record |
| **Segment recording** | For persistent agents: append segment history |
| **Attachment handling** | Write large outputs to `attachments/` directory, store path in DB |
| **Atomic writes** | Use transactions when updating multiple related records |
**Critical:** Subagents write ONLY to `bindings`, `agents`, and `agent_segments` tables. The VM owns the `execution` table entirely. Completion signaling happens through the substrate (Task tool return), not database updates.
**Critical:** Subagents must write their outputs directly to the database. The VM does not write subagent outputs—it only reads them after the subagent completes.
**What subagents return to the VM:** A confirmation message with the binding location—not the full content:
**Root scope:**
```
Binding written: research
Location: .prose/runs/20260116-143052-a7b3c9/state.db (bindings table, name='research', execution_id=NULL)
Summary: AI safety research covering alignment, robustness, and interpretability with 15 citations.
```
**Inside block invocation:**
```
Binding written: result
Location: .prose/runs/20260116-143052-a7b3c9/state.db (bindings table, name='result', execution_id=43)
Execution ID: 43
Summary: Processed chunk into 3 sub-parts for recursive processing.
```
The VM tracks locations, not values. This keeps the VM's context lean and enables arbitrarily large intermediate values.
### Shared Concerns
| Concern | Who Handles |
|---------|-------------|
| Schema evolution | Either (use `CREATE TABLE IF NOT EXISTS`, `ALTER TABLE` as needed) |
| Custom tables | Either (prefix with `x_` for extensions) |
| Indexing | Either (add indexes for frequently-queried columns) |
| Cleanup | VM (at run end, optionally vacuum) |
---
## Core Schema
The VM initializes these tables. This is a **minimum viable schema**—extend freely.
```sql
-- Run metadata
CREATE TABLE IF NOT EXISTS run (
id TEXT PRIMARY KEY,
program_path TEXT,
program_source TEXT,
started_at TEXT DEFAULT (datetime('now')),
updated_at TEXT DEFAULT (datetime('now')),
status TEXT DEFAULT 'running', -- running, completed, failed, interrupted
state_mode TEXT DEFAULT 'sqlite'
);
-- Execution position and history
CREATE TABLE IF NOT EXISTS execution (
id INTEGER PRIMARY KEY AUTOINCREMENT,
statement_index INTEGER,
statement_text TEXT,
status TEXT, -- pending, executing, completed, failed, skipped
started_at TEXT,
completed_at TEXT,
error_message TEXT,
parent_id INTEGER REFERENCES execution(id), -- for nested blocks
metadata TEXT -- JSON for construct-specific data (loop iteration, parallel branch, etc.)
);
-- All named values (input, output, let, const)
CREATE TABLE IF NOT EXISTS bindings (
name TEXT,
execution_id INTEGER, -- NULL for root scope, non-null for block invocations
kind TEXT, -- input, output, let, const
value TEXT,
source_statement TEXT,
created_at TEXT DEFAULT (datetime('now')),
updated_at TEXT DEFAULT (datetime('now')),
attachment_path TEXT, -- if value is too large, store path to file
PRIMARY KEY (name, IFNULL(execution_id, -1)) -- IFNULL handles NULL for root scope
);
-- Persistent agent memory
CREATE TABLE IF NOT EXISTS agents (
name TEXT PRIMARY KEY,
scope TEXT, -- execution, project, user, custom
memory TEXT,
created_at TEXT DEFAULT (datetime('now')),
updated_at TEXT DEFAULT (datetime('now'))
);
-- Agent invocation history
CREATE TABLE IF NOT EXISTS agent_segments (
id INTEGER PRIMARY KEY AUTOINCREMENT,
agent_name TEXT REFERENCES agents(name),
segment_number INTEGER,
timestamp TEXT DEFAULT (datetime('now')),
prompt TEXT,
summary TEXT,
UNIQUE(agent_name, segment_number)
);
-- Import registry
CREATE TABLE IF NOT EXISTS imports (
alias TEXT PRIMARY KEY,
source_url TEXT,
fetched_at TEXT,
inputs_schema TEXT, -- JSON
outputs_schema TEXT -- JSON
);
```
### Schema Conventions
- **Timestamps**: Use ISO 8601 format (`datetime('now')`)
- **JSON fields**: Store structured data as JSON text in `metadata`, `*_schema` columns
- **Large values**: If a binding value exceeds ~100KB, write to `attachments/{name}.md` and store path
- **Extension tables**: Prefix with `x_` (e.g., `x_metrics`, `x_audit_log`)
- **Anonymous bindings**: Sessions without explicit capture (`session "..."` without `let x =`) use auto-generated names: `anon_001`, `anon_002`, etc.
- **Import bindings**: Prefix with import alias for scoping: `research.findings`, `research.sources`
- **Scoped bindings**: Use `execution_id` column—NULL for root scope, non-null for block invocations
### Scope Resolution Query
For recursive blocks, bindings are scoped to their execution frame. Resolve variables by walking up the call stack:
```sql
-- Find binding 'result' starting from execution_id 43
WITH RECURSIVE scope_chain AS (
-- Start with current execution
SELECT id, parent_id FROM execution WHERE id = 43
UNION ALL
-- Walk up to parent
SELECT e.id, e.parent_id
FROM execution e
JOIN scope_chain s ON e.id = s.parent_id
)
SELECT b.* FROM bindings b
LEFT JOIN scope_chain s ON b.execution_id = s.id
WHERE b.name = 'result'
AND (b.execution_id IN (SELECT id FROM scope_chain) OR b.execution_id IS NULL)
ORDER BY
CASE WHEN b.execution_id IS NULL THEN 1 ELSE 0 END, -- Prefer scoped over root
s.id DESC NULLS LAST -- Prefer deeper (more local) scope
LIMIT 1;
```
**Simpler version if you know the scope chain:**
```sql
-- Direct lookup: check current scope, then parent, then root
SELECT * FROM bindings
WHERE name = 'result'
AND (execution_id = 43 OR execution_id = 42 OR execution_id IS NULL)
ORDER BY execution_id DESC NULLS LAST
LIMIT 1;
```
---
## Database Interaction
Both VM and subagents interact via the `sqlite3` CLI.
### From the VM
```bash
# Initialize database
sqlite3 .prose/runs/20260116-143052-a7b3c9/state.db "CREATE TABLE IF NOT EXISTS..."
# Update execution position
sqlite3 .prose/runs/20260116-143052-a7b3c9/state.db "
INSERT INTO execution (statement_index, statement_text, status, started_at)
VALUES (3, 'session \"Research AI safety\"', 'executing', datetime('now'))
"
# Read a binding
sqlite3 -json .prose/runs/20260116-143052-a7b3c9/state.db "
SELECT value FROM bindings WHERE name = 'research'
"
# Check parallel branch status
sqlite3 .prose/runs/20260116-143052-a7b3c9/state.db "
SELECT statement_text, status FROM execution
WHERE json_extract(metadata, '$.parallel_id') = 'p1'
"
```
### From Subagents
The VM provides the database path and instructions when spawning:
**Root scope (outside block invocations):**
```
Your output database is:
.prose/runs/20260116-143052-a7b3c9/state.db
When complete, write your output:
sqlite3 .prose/runs/20260116-143052-a7b3c9/state.db "
INSERT OR REPLACE INTO bindings (name, execution_id, kind, value, source_statement, updated_at)
VALUES (
'research',
NULL, -- root scope
'let',
'AI safety research covers alignment, robustness...',
'let research = session: researcher',
datetime('now')
)
"
```
**Inside block invocation (include execution_id):**
```
Execution scope:
execution_id: 43
block: process
depth: 3
Your output database is:
.prose/runs/20260116-143052-a7b3c9/state.db
When complete, write your output:
sqlite3 .prose/runs/20260116-143052-a7b3c9/state.db "
INSERT OR REPLACE INTO bindings (name, execution_id, kind, value, source_statement, updated_at)
VALUES (
'result',
43, -- scoped to this execution
'let',
'Processed chunk into 3 sub-parts...',
'let result = session \"Process chunk\"',
datetime('now')
)
"
```
For persistent agents (execution-scoped):
```
Your memory is in the database:
.prose/runs/20260116-143052-a7b3c9/state.db
Read your current state:
sqlite3 -json .prose/runs/20260116-143052-a7b3c9/state.db "SELECT memory FROM agents WHERE name = 'captain'"
Update when done:
sqlite3 .prose/runs/20260116-143052-a7b3c9/state.db "UPDATE agents SET memory = '...', updated_at = datetime('now') WHERE name = 'captain'"
Record this segment:
sqlite3 .prose/runs/20260116-143052-a7b3c9/state.db "INSERT INTO agent_segments (agent_name, segment_number, prompt, summary) VALUES ('captain', 3, '...', '...')"
```
For project-scoped agents, use `.prose/agents.db`. For user-scoped agents, use `~/.prose/agents.db`.
---
## Context Preservation in Main Thread
**This is critical.** The database is for persistence and coordination, but the VM must still maintain conversational context.
### What the VM Must Narrate
Even with SQLite state, the VM should narrate key events in its conversation:
```
[Position] Statement 3: let research = session: researcher
Spawning session, will write to state.db
[Task tool call]
[Success] Session complete, binding written to DB
[Binding] research = <stored in state.db>
```
### Why Both?
| Purpose | Mechanism |
|---------|-----------|
| **Working memory** | Conversation narration (what the VM "remembers" without re-querying) |
| **Durable state** | SQLite database (survives context limits, enables resumption) |
| **Subagent coordination** | SQLite database (shared access point) |
| **Debugging/inspection** | SQLite database (queryable history) |
The narration is the VM's "mental model" of execution. The database is the "source of truth" for resumption and inspection.
---
## Parallel Execution
For parallel blocks, the VM uses the `metadata` JSON field to track branches. **Only the VM writes to the `execution` table.**
```sql
-- VM marks parallel start
INSERT INTO execution (statement_index, statement_text, status, metadata)
VALUES (5, 'parallel:', 'executing', '{"parallel_id": "p1", "strategy": "all", "branches": ["a", "b", "c"]}');
-- VM creates execution record for each branch
INSERT INTO execution (statement_index, statement_text, status, parent_id, metadata)
VALUES (6, 'a = session "Task A"', 'executing', 5, '{"parallel_id": "p1", "branch": "a"}');
-- Subagent writes its output to bindings table (see "From Subagents" section)
-- Task tool signals completion to VM via substrate
-- VM marks branch complete after Task returns
UPDATE execution SET status = 'completed', completed_at = datetime('now')
WHERE json_extract(metadata, '$.parallel_id') = 'p1' AND json_extract(metadata, '$.branch') = 'a';
-- VM checks if all branches complete
SELECT COUNT(*) as pending FROM execution
WHERE json_extract(metadata, '$.parallel_id') = 'p1' AND status != 'completed';
```
---
## Loop Tracking
```sql
-- Loop metadata tracks iteration state
INSERT INTO execution (statement_index, statement_text, status, metadata)
VALUES (10, 'loop until **analysis complete** (max: 5):', 'executing',
'{"loop_id": "l1", "max_iterations": 5, "current_iteration": 0, "condition": "**analysis complete**"}');
-- Update iteration
UPDATE execution
SET metadata = json_set(metadata, '$.current_iteration', 2),
updated_at = datetime('now')
WHERE json_extract(metadata, '$.loop_id') = 'l1';
```
---
## Error Handling
```sql
-- Record failure
UPDATE execution
SET status = 'failed',
error_message = 'Connection timeout after 30s',
completed_at = datetime('now')
WHERE id = 15;
-- Track retry attempts in metadata
UPDATE execution
SET metadata = json_set(metadata, '$.retry_attempt', 2, '$.max_retries', 3)
WHERE id = 15;
```
---
## Large Outputs
When a binding value is too large for comfortable database storage (>100KB):
1. Write content to `attachments/{binding_name}.md`
2. Store the path in the `attachment_path` column
3. Leave `value` as a summary or null
```sql
INSERT INTO bindings (name, kind, value, attachment_path, source_statement)
VALUES (
'full_report',
'let',
'Full analysis report (847KB) - see attachment',
'attachments/full_report.md',
'let full_report = session "Generate comprehensive report"'
);
```
---
## Resuming Execution
To resume an interrupted run:
```sql
-- Find current position
SELECT statement_index, statement_text, status
FROM execution
WHERE status = 'executing'
ORDER BY id DESC LIMIT 1;
-- Get all completed bindings
SELECT name, kind, value, attachment_path FROM bindings;
-- Get agent memory states
SELECT name, memory FROM agents;
-- Check parallel block status
SELECT json_extract(metadata, '$.branch') as branch, status
FROM execution
WHERE json_extract(metadata, '$.parallel_id') IS NOT NULL
AND parent_id = (SELECT id FROM execution WHERE status = 'executing' AND statement_text LIKE 'parallel:%');
```
---
## Flexibility Encouragement
Unlike filesystem state, SQLite state is intentionally **less prescriptive**. The core schema is a starting point. You are encouraged to:
- **Add columns** to existing tables as needed
- **Create extension tables** (prefix with `x_`)
- **Store custom metrics** (timing, token counts, model info)
- **Build indexes** for your query patterns
- **Use JSON functions** for semi-structured data
Example extensions:
```sql
-- Custom metrics table
CREATE TABLE x_metrics (
execution_id INTEGER REFERENCES execution(id),
metric_name TEXT,
metric_value REAL,
recorded_at TEXT DEFAULT (datetime('now'))
);
-- Add custom column
ALTER TABLE bindings ADD COLUMN token_count INTEGER;
-- Create index for common query
CREATE INDEX idx_execution_status ON execution(status);
```
The database is your workspace. Use it.
---
## Comparison with Other Modes
| Aspect | filesystem.md | in-context.md | sqlite.md |
|--------|---------------|---------------|-----------|
| **State location** | `.prose/runs/{id}/` files | Conversation history | `.prose/runs/{id}/state.db` |
| **Queryable** | Via file reads | No | Yes (SQL) |
| **Atomic updates** | No | N/A | Yes (transactions) |
| **Schema flexibility** | Rigid file structure | N/A | Flexible (add tables/columns) |
| **Resumption** | Read state.md | Re-read conversation | Query database |
| **Complexity ceiling** | High | Low (<30 statements) | High |
| **Dependency** | None | None | sqlite3 CLI |
| **Status** | Stable | Stable | **Experimental** |
---
## Summary
SQLite state management:
1. Uses a **single database file** per run
2. Provides **clear responsibility separation** between VM and subagents
3. Enables **structured queries** for state inspection
4. Supports **atomic transactions** for reliable updates
5. Allows **flexible schema evolution** as needed
6. Requires the **sqlite3 CLI** tool
7. Is **experimental**—expect changes
The core contract: the VM manages execution flow and spawns subagents; subagents write their own outputs directly to the database. Both maintain the principle that what happens is recorded, and what is recorded can be queried.
