## Summary
- Replace broken prompt-based Stop hook with command-based hook using
Claude Sonnet
- Add .claude/hooks/stop-hook.py that reads conversation transcript and
uses Sonnet to analyze task completion
- Includes infinite loop prevention via stop_hook_active check
- Add unit tests for the stop hook

## Test plan
- [x] Run pytest .claude/hooks/tests/test_stop_hook.py -v - all 9 tests
pass
- [ ] Manual testing: verify stop hook fires and correctly analyzes task
completion

## Summary by cubic
Replaced the broken prompt-based stop hook with a command-based hook
that blocks when tasks remain and uses Sonnet analysis as a fallback.
Adds loop protection and tests.

- **New Features**
- Added .claude/hooks/stop-hook.py that blocks when
TaskCreate/TaskUpdate show remaining tasks, returning
{"decision":"block","reason":...}. If none remain, it analyzes a 32k
transcript (middle truncation) with Sonnet.
- Added unit tests and a stop_hook_active guard to prevent infinite
loops.

- **Refactors**
- Updated .claude/settings.json to use the command-based hook (30000 ms
timeout) instead of the prompt hook.
- Added --no-session-persistence to Claude CLI calls in stop-hook.py and
permission-request-hook.py.

<sup>Written for commit 575426cee9efb0fa7e1f4be64a8405ae2e717a3b.
Summary will update on new commits.</sup>
