+# 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.
