# Context Manager Task 6 Implementer Report

## Status
Implemented and verified.

## What you implemented
- Wired the context manager runtime into the extension entrypoint in `.pi/agent/extensions/context-manager/index.ts`.
- Registered the required slash commands through new `src/commands.ts`:
  - `/ctx-status`
  - `/ctx-memory`
  - `/ctx-refresh`
  - `/ctx-compact`
  - `/ctx-mode`
- Registered the required pi hooks in `index.ts`:
  - `session_start`
  - `tool_result`
  - `turn_end`
  - `context`
  - `session_before_compact`
  - `session_before_tree`
- Added `src/extension.test.ts` to verify the extension registers the expected commands and hooks.

## What you tested and results
1. Wrote `src/extension.test.ts` first and ran:
   - `cd /home/alex/dotfiles/.worktrees/context-manager-extension/.pi/agent/extensions/context-manager && npx tsx --test src/extension.test.ts`
   - Result before implementation: **FAIL** as expected because the extension registered no commands/hooks yet.
2. Ran the required targeted test again after implementation:
   - `cd /home/alex/dotfiles/.worktrees/context-manager-extension/.pi/agent/extensions/context-manager && npx tsx --test src/extension.test.ts`
   - Result: **PASS**
3. Ran the full package test suite:
   - `cd /home/alex/dotfiles/.worktrees/context-manager-extension/.pi/agent/extensions/context-manager && npm test`
   - Result: **PASS** (`36` tests passed, `0` failed)

## Files changed
- Modified: `.pi/agent/extensions/context-manager/index.ts`
- Created: `.pi/agent/extensions/context-manager/src/commands.ts`
- Created: `.pi/agent/extensions/context-manager/src/extension.test.ts`
- Created: `.pi/reviews/context-manager-task6-implementer-report.md`

## Self-review findings
- Implementation matches the required command names and hook names exactly.
- The runtime is restored from persisted snapshots on `session_start` and persisted again on `turn_end`.
- The context hook prunes bulky tool results and injects the built packet as a hidden custom message only when packet text exists.
- Compaction and tree hooks delegate summary generation to the runtime helpers without introducing unrelated scope.

## Any concerns
- No functional concerns with Task 6 implementation.
- The worktree already contained unrelated untracked review artifacts before this task; they were not part of this implementation.
