feat: Add Kilo Gateway provider (#20212)

* feat: Add Kilo Gateway provider Add support for Kilo Gateway as a model provider, similar to OpenRouter. Kilo Gateway provides a unified API that routes requests to many models behind a single endpoint and API key. Changes: - Add kilocode provider option to auth-choice and onboarding flows - Add KILOCODE_API_KEY environment variable support - Add kilocode/ model prefix handling in model-auth and extra-params - Add provider documentation in docs/providers/kilocode.md - Update model-providers.md with Kilo Gateway section - Add design doc for the integration * kilocode: add provider tests and normalize onboard auth-choice registration * kilocode: register in resolveImplicitProviders so models appear in provider filter * kilocode: update base URL from /api/openrouter/ to /api/gateway/ * docs: fix formatting in kilocode docs * fix: address PR review — remove kilocode from cacheRetention, fix stale model refs and CLI name in docs, fix TS2742 * docs: fix stale refs in design doc — Moltbot to OpenClaw, MoltbotConfig to OpenClawConfig, remove extra-params section, fix doc path * fix: use resolveAgentModelPrimaryValue for AgentModelConfig union type --------- Co-authored-by: Mark IJbema <mark@kilocode.ai>

+# Kilo Gateway Provider Integration Design
+
+## Overview
+
+This document outlines the design for integrating "Kilo Gateway" as a first-class provider in OpenClaw, modeled after the existing OpenRouter implementation. Kilo Gateway uses an OpenAI-compatible completions API with a different base URL.
+
+## Design Decisions
+
+### 1. Provider Naming
+
+**Recommendation: `kilocode`**
+
+Rationale:
+
+- Matches the user config example provided (`kilocode` provider key)
+- Consistent with existing provider naming patterns (e.g., `openrouter`, `opencode`, `moonshot`)
+- Short and memorable
+- Avoids confusion with generic "kilo" or "gateway" terms
+
+Alternative considered: `kilo-gateway` - rejected because hyphenated names are less common in the codebase and `kilocode` is more concise.
+
+### 2. Default Model Reference
+
+**Recommendation: `kilocode/anthropic/claude-opus-4.6`**
+
+Rationale:
+
+- Based on user config example
+- Claude Opus 4.5 is a capable default model
+- Explicit model selection avoids reliance on auto-routing
+
+### 3. Base URL Configuration
+
+**Recommendation: Hardcoded default with config override**
+
+- **Default Base URL:** `https://api.kilo.ai/api/gateway/`
+- **Configurable:** Yes, via `models.providers.kilocode.baseUrl`
+
+This matches the pattern used by other providers like Moonshot, Venice, and Synthetic.
+
+### 4. Model Scanning
+
+**Recommendation: No dedicated model scanning endpoint initially**
+
+Rationale:
+
+- Kilo Gateway proxies to OpenRouter, so models are dynamic
+- Users can manually configure models in their config
+- If Kilo Gateway exposes a `/models` endpoint in the future, scanning can be added
+
+### 5. Special Handling
+
+**Recommendation: Inherit OpenRouter behavior for Anthropic models**
+
+Since Kilo Gateway proxies to OpenRouter, the same special handling should apply:
+
+- Cache TTL eligibility for `anthropic/*` models
+- Extra params (cacheControlTtl) for `anthropic/*` models
+- Transcript policy follows OpenRouter patterns
+
+## Files to Modify
+
+### Core Credential Management
+
+#### 1. `src/commands/onboard-auth.credentials.ts`
+
+Add:
+
+```typescript
+export const KILOCODE_DEFAULT_MODEL_REF = "kilocode/anthropic/claude-opus-4.6";
+
+export async function setKilocodeApiKey(key: string, agentDir?: string) {
+  upsertAuthProfile({
+    profileId: "kilocode:default",
+    credential: {
+      type: "api_key",
+      provider: "kilocode",
+      key,
+    },
+    agentDir: resolveAuthAgentDir(agentDir),
+  });
+}
+```
+
+#### 2. `src/agents/model-auth.ts`
+
+Add to `envMap` in `resolveEnvApiKey()`:
+
+```typescript
+const envMap: Record<string, string> = {
+  // ... existing entries
+  kilocode: "KILOCODE_API_KEY",
+};
+```
+
+#### 3. `src/config/io.ts`
+
+Add to `SHELL_ENV_EXPECTED_KEYS`:
+
+```typescript
+const SHELL_ENV_EXPECTED_KEYS = [
+  // ... existing entries
+  "KILOCODE_API_KEY",
+];
+```
+
+### Config Application
+
+#### 4. `src/commands/onboard-auth.config-core.ts`
+
+Add new functions:
+
+```typescript
+export const KILOCODE_BASE_URL = "https://api.kilo.ai/api/gateway/";
+
+export function applyKilocodeProviderConfig(cfg: OpenClawConfig): OpenClawConfig {
+  const models = { ...cfg.agents?.defaults?.models };
+  models[KILOCODE_DEFAULT_MODEL_REF] = {
+    ...models[KILOCODE_DEFAULT_MODEL_REF],
+    alias: models[KILOCODE_DEFAULT_MODEL_REF]?.alias ?? "Kilo Gateway",
+  };
+
+  const providers = { ...cfg.models?.providers };
+  const existingProvider = providers.kilocode;
+  const { apiKey: existingApiKey, ...existingProviderRest } = (existingProvider ?? {}) as Record<
+    string,
+    unknown
+  > as { apiKey?: string };
+  const resolvedApiKey = typeof existingApiKey === "string" ? existingApiKey : undefined;
+  const normalizedApiKey = resolvedApiKey?.trim();
+
+  providers.kilocode = {
+    ...existingProviderRest,
+    baseUrl: KILOCODE_BASE_URL,
+    api: "openai-completions",
+    ...(normalizedApiKey ? { apiKey: normalizedApiKey } : {}),
+  };
+
+  return {
+    ...cfg,
+    agents: {
+      ...cfg.agents,
+      defaults: {
+        ...cfg.agents?.defaults,
+        models,
+      },
+    },
+    models: {
+      mode: cfg.models?.mode ?? "merge",
+      providers,
+    },
+  };
+}
+
+export function applyKilocodeConfig(cfg: OpenClawConfig): OpenClawConfig {
+  const next = applyKilocodeProviderConfig(cfg);
+  const existingModel = next.agents?.defaults?.model;
+  return {
+    ...next,
+    agents: {
+      ...next.agents,
+      defaults: {
+        ...next.agents?.defaults,
+        model: {
+          ...(existingModel && "fallbacks" in (existingModel as Record<string, unknown>)
+            ? {
+                fallbacks: (existingModel as { fallbacks?: string[] }).fallbacks,
+              }
+            : undefined),
+          primary: KILOCODE_DEFAULT_MODEL_REF,
+        },
+      },
+    },
+  };
+}
+```
+
+### Auth Choice System
+
+#### 5. `src/commands/onboard-types.ts`
+
+Add to `AuthChoice` type:
+
+```typescript
+export type AuthChoice =
+  // ... existing choices
+  "kilocode-api-key";
+// ...
+```
+
+Add to `OnboardOptions`:
+
+```typescript
+export type OnboardOptions = {
+  // ... existing options
+  kilocodeApiKey?: string;
+  // ...
+};
+```
+
+#### 6. `src/commands/auth-choice-options.ts`
+
+Add to `AuthChoiceGroupId`:
+
+```typescript
+export type AuthChoiceGroupId =
+  // ... existing groups
+  "kilocode";
+// ...
+```
+
+Add to `AUTH_CHOICE_GROUP_DEFS`:
+
+```typescript
+{
+  value: "kilocode",
+  label: "Kilo Gateway",
+  hint: "API key (OpenRouter-compatible)",
+  choices: ["kilocode-api-key"],
+},
+```
+
+Add to `buildAuthChoiceOptions()`:
+
+```typescript
+options.push({
+  value: "kilocode-api-key",
+  label: "Kilo Gateway API key",
+  hint: "OpenRouter-compatible gateway",
+});
+```
+
+#### 7. `src/commands/auth-choice.preferred-provider.ts`
+
+Add mapping:
+
+```typescript
+const PREFERRED_PROVIDER_BY_AUTH_CHOICE: Partial<Record<AuthChoice, string>> = {
+  // ... existing mappings
+  "kilocode-api-key": "kilocode",
+};
+```
+
+### Auth Choice Application
+
+#### 8. `src/commands/auth-choice.apply.api-providers.ts`
+
+Add import:
+
+```typescript
+import {
+  // ... existing imports
+  applyKilocodeConfig,
+  applyKilocodeProviderConfig,
+  KILOCODE_DEFAULT_MODEL_REF,
+  setKilocodeApiKey,
+} from "./onboard-auth.js";
+```
+
+Add handling for `kilocode-api-key`:
+
+```typescript
+if (authChoice === "kilocode-api-key") {
+  const store = ensureAuthProfileStore(params.agentDir, {
+    allowKeychainPrompt: false,
+  });
+  const profileOrder = resolveAuthProfileOrder({
+    cfg: nextConfig,
+    store,
+    provider: "kilocode",
+  });
+  const existingProfileId = profileOrder.find((profileId) => Boolean(store.profiles[profileId]));
+  const existingCred = existingProfileId ? store.profiles[existingProfileId] : undefined;
+  let profileId = "kilocode:default";
+  let mode: "api_key" | "oauth" | "token" = "api_key";
+  let hasCredential = false;
+
+  if (existingProfileId && existingCred?.type) {
+    profileId = existingProfileId;
+    mode =
+      existingCred.type === "oauth" ? "oauth" : existingCred.type === "token" ? "token" : "api_key";
+    hasCredential = true;
+  }
+
+  if (!hasCredential && params.opts?.token && params.opts?.tokenProvider === "kilocode") {
+    await setKilocodeApiKey(normalizeApiKeyInput(params.opts.token), params.agentDir);
+    hasCredential = true;
+  }
+
+  if (!hasCredential) {
+    const envKey = resolveEnvApiKey("kilocode");
+    if (envKey) {
+      const useExisting = await params.prompter.confirm({
+        message: `Use existing KILOCODE_API_KEY (${envKey.source}, ${formatApiKeyPreview(envKey.apiKey)})?`,
+        initialValue: true,
+      });
+      if (useExisting) {
+        await setKilocodeApiKey(envKey.apiKey, params.agentDir);
+        hasCredential = true;
+      }
+    }
+  }
+
+  if (!hasCredential) {
+    const key = await params.prompter.text({
+      message: "Enter Kilo Gateway API key",
+      validate: validateApiKeyInput,
+    });
+    await setKilocodeApiKey(normalizeApiKeyInput(String(key)), params.agentDir);
+    hasCredential = true;
+  }
+
+  if (hasCredential) {
+    nextConfig = applyAuthProfileConfig(nextConfig, {
+      profileId,
+      provider: "kilocode",
+      mode,
+    });
+  }
+  {
+    const applied = await applyDefaultModelChoice({
+      config: nextConfig,
+      setDefaultModel: params.setDefaultModel,
+      defaultModel: KILOCODE_DEFAULT_MODEL_REF,
+      applyDefaultConfig: applyKilocodeConfig,
+      applyProviderConfig: applyKilocodeProviderConfig,
+      noteDefault: KILOCODE_DEFAULT_MODEL_REF,
+      noteAgentModel,
+      prompter: params.prompter,
+    });
+    nextConfig = applied.config;
+    agentModelOverride = applied.agentModelOverride ?? agentModelOverride;
+  }
+  return { config: nextConfig, agentModelOverride };
+}
+```
+
+Also add tokenProvider mapping at the top of the function:
+
+```typescript
+if (params.opts.tokenProvider === "kilocode") {
+  authChoice = "kilocode-api-key";
+}
+```
+
+### CLI Registration
+
+#### 9. `src/cli/program/register.onboard.ts`
+
+Add CLI option:
+
+```typescript
+.option("--kilocode-api-key <key>", "Kilo Gateway API key")
+```
+
+Add to action handler:
+
+```typescript
+kilocodeApiKey: opts.kilocodeApiKey as string | undefined,
+```
+
+Update auth-choice help text:
+
+```typescript
+.option(
+  "--auth-choice <choice>",
+  "Auth: setup-token|token|chutes|openai-codex|openai-api-key|openrouter-api-key|kilocode-api-key|ai-gateway-api-key|...",
+)
+```
+
+### Non-Interactive Onboarding
+
+#### 10. `src/commands/onboard-non-interactive/local/auth-choice.ts`
+
+Add handling for `kilocode-api-key`:
+
+```typescript
+if (authChoice === "kilocode-api-key") {
+  const resolved = await resolveNonInteractiveApiKey({
+    provider: "kilocode",
+    cfg: baseConfig,
+    flagValue: opts.kilocodeApiKey,
+    flagName: "--kilocode-api-key",
+    envVar: "KILOCODE_API_KEY",
+  });
+  await setKilocodeApiKey(resolved.apiKey, agentDir);
+  nextConfig = applyAuthProfileConfig(nextConfig, {
+    profileId: "kilocode:default",
+    provider: "kilocode",
+    mode: "api_key",
+  });
+  // ... apply default model
+}
+```
+
+### Export Updates
+
+#### 11. `src/commands/onboard-auth.ts`
+
+Add exports:
+
+```typescript
+export {
+  // ... existing exports
+  applyKilocodeConfig,
+  applyKilocodeProviderConfig,
+  KILOCODE_BASE_URL,
+} from "./onboard-auth.config-core.js";
+
+export {
+  // ... existing exports
+  KILOCODE_DEFAULT_MODEL_REF,
+  setKilocodeApiKey,
+} from "./onboard-auth.credentials.js";
+```
+
+### Special Handling (Optional)
+
+#### 12. `src/agents/pi-embedded-runner/cache-ttl.ts`
+
+Add Kilo Gateway support for Anthropic models:
+
+```typescript
+export function isCacheTtlEligibleProvider(provider: string, modelId: string): boolean {
+  const normalizedProvider = provider.toLowerCase();
+  const normalizedModelId = modelId.toLowerCase();
+  if (normalizedProvider === "anthropic") return true;
+  if (normalizedProvider === "openrouter" && normalizedModelId.startsWith("anthropic/"))
+    return true;
+  if (normalizedProvider === "kilocode" && normalizedModelId.startsWith("anthropic/")) return true;
+  return false;
+}
+```
+
+#### 13. `src/agents/transcript-policy.ts`
+
+Add Kilo Gateway handling (similar to OpenRouter):
+
+```typescript
+const isKilocodeGemini = provider === "kilocode" && modelId.toLowerCase().includes("gemini");
+
+// Include in needsNonImageSanitize check
+const needsNonImageSanitize =
+  isGoogle || isAnthropic || isMistral || isOpenRouterGemini || isKilocodeGemini;
+```
+
+## Configuration Structure
+
+### User Config Example
+
+```json
+{
+  "models": {
+    "mode": "merge",
+    "providers": {
+      "kilocode": {
+        "baseUrl": "https://api.kilo.ai/api/gateway/",
+        "apiKey": "xxxxx",
+        "api": "openai-completions",
+        "models": [
+          {
+            "id": "anthropic/claude-opus-4.6",
+            "name": "Anthropic: Claude Opus 4.6"
+          },
+          { "id": "minimax/minimax-m2.1:free", "name": "Minimax: Minimax M2.1" }
+        ]
+      }
+    }
+  }
+}
+```
+
+### Auth Profile Structure
+
+```json
+{
+  "profiles": {
+    "kilocode:default": {
+      "type": "api_key",
+      "provider": "kilocode",
+      "key": "xxxxx"
+    }
+  }
+}
+```
+
+## Testing Considerations
+
+1. **Unit Tests:**
+   - Test `setKilocodeApiKey()` writes correct profile
+   - Test `applyKilocodeConfig()` sets correct defaults
+   - Test `resolveEnvApiKey("kilocode")` returns correct env var
+
+2. **Integration Tests:**
+   - Test onboarding flow with `--auth-choice kilocode-api-key`
+   - Test non-interactive onboarding with `--kilocode-api-key`
+   - Test model selection with `kilocode/` prefix
+
+3. **E2E Tests:**
+   - Test actual API calls through Kilo Gateway (live tests)
+
+## Migration Notes
+
+- No migration needed for existing users
+- New users can immediately use `kilocode-api-key` auth choice
+- Existing manual config with `kilocode` provider will continue to work
+
+## Future Considerations
+
+1. **Model Catalog:** If Kilo Gateway exposes a `/models` endpoint, add scanning support similar to `scanOpenRouterModels()`
+
+2. **OAuth Support:** If Kilo Gateway adds OAuth, extend the auth system accordingly
+
+3. **Rate Limiting:** Consider adding rate limit handling specific to Kilo Gateway if needed
+
+4. **Documentation:** Add docs at `docs/providers/kilocode.md` explaining setup and usage

+read_when:
+  - You want a single API key for many LLMs
+  - You want to run models via Kilo Gateway in OpenClaw
+---
+
+# Kilo Gateway
+
+Kilo Gateway provides a **unified API** that routes requests to many models behind a single
+endpoint and API key. It is OpenAI-compatible, so most OpenAI SDKs work by switching the base URL.
+
+## Getting an API key
+
+1. Go to [app.kilo.ai](https://app.kilo.ai)
+2. Sign in or create an account
+3. Navigate to API Keys and generate a new key
+
+## CLI setup
+
+```bash
+openclaw onboard --kilocode-api-key <key>
+```
+
+Or set the environment variable:
+
+```bash
+export KILOCODE_API_KEY="your-api-key"
+```
+
+## Config snippet
+
+```json5
+{
+  env: { KILOCODE_API_KEY: "sk-..." },
+  agents: {
+    defaults: {
+      model: { primary: "kilocode/anthropic/claude-opus-4.6" },
+    },
+  },
+}
+```
+
+## Notes
+
+- Model refs are `kilocode/<provider>/<model>` (e.g., `kilocode/anthropic/claude-opus-4.6`).
+- Default model: `kilocode/anthropic/claude-opus-4.6`
+- Base URL: `https://api.kilo.ai/api/gateway/`
+- For more model/provider options, see [/concepts/model-providers](/concepts/model-providers).
+- Kilo Gateway uses a Bearer token with your API key under the hood.
