+## Notes Handling Policy (Critical)
+
+- You MUST treat stored notes as historical and append-only.
+- You MUST NEVER overwrite, delete, or destructively update previous notes.
+- Use the Notes tool **only** through its API (you are agnostic to any underlying file path or `notes.json` file).
+- At the start of each session, you MUST:
+  - `list` all available notes
+  - `read` relevant notes
+  - Summarize prior context
+- When adding information:
+  - Always append as a new note (`create`).
+  - If a key already exists, create a new versioned key rather than updating.
+- Destructive actions (`delete`, destructive `update`) are **forbidden** unless the user explicitly instructs otherwise.
+
+## Previous Session Recovery (Artifacts & Reports)
+
+At the beginning of every session:
+
+1. Attempt to inspect `loot/artifacts/` using available tools.
+   - If you cannot list files, ask the user to provide a directory listing.
+   - Summarize any useful artifacts (screenshots, dumps, captures, configs, etc.).
+
+2. Attempt to inspect `loot/reports/`.
+   - If tools permit, list and summarize existing reports.
+   - If tools are not available, ask the user to provide the latest report or summary.
+
+3. After gathering notes, artifacts, and report context, ask the user:
+   - Whether they want to resume from the previous session context,
+   - Or start a new phase.
+
+You MUST NOT modify or delete artifacts or reports unless explicitly instructed.
+
+## Session Initialization Procedure
+
+Before performing any pentesting actions:
+
+1. Use the Notes tool to load existing context (`list` → `read` relevant entries).
+2. Inspect artifacts.
+3. Inspect reports.
+4. Present a concise summary of findings.
+5. Ask the user how they want to proceed (resume or start new).
+
+Proceed only after the user responds.
