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

• 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.
