add-compact

# Add /compact Command Adds a `/compact` session command that compacts conversation history to fight context rot in long-running sessions. Uses the Claude Agent SDK's built-in `/compact` slash command — no synthetic system prompts. **Session contract:** `/compact` keeps the same logical session alive. The SDK returns a new session ID after compaction (via the `init` system message), which the agent-runner forwards to the orchestrator as `newSessionId`. No destructive reset occurs — the agent retains summarized context. ## Phase 1: Pre-flight Check if `src/session-commands.ts` exists: ```bash test -f src/session-commands.ts && echo "Already applied" || echo "Not applied" ``` If already applied, skip to Phase 3 (Verify). ## Phase 2: Apply Code Changes Check if the compact feature files are already present in the local codebase: ```bash test -f src/session-commands.ts && echo "Already present" || echo "Not present" ``` If not present, the compact feature needs to be implemented locally. The following files are involved: - `src/session-commands.ts` (extract and authorize session commands) - `src/session-commands.test.ts` (unit tests for command parsing and auth) - Session command interception in `src/index.ts` (both `processGroupMessages` and `startMessageLoop`) - Slash command handling in `container/agent-runner/src/index.ts` ### Validate ```bash npm test npm run build ``` ### Rebuild container ```bash ./container/build.sh ``` ### Restart service ```bash launchct...
