Hooks are configured in settings.json and fire automatically at specific points in a Claude Code session.

Hook Trigger Script
WorktreeCreate Developer creates a worktree git worktree add + echo path
WorktreeRemove Developer removes a worktree git worktree remove --force
SessionEnd Any session ends hooks/on_session_end.sh (async)

hooks/on_session_end.sh

Runs asynchronously at the end of every session:

  1. Logs a session_end event to project/logs/events.json
  2. Compares project/rapports/problems/ against .rapport_manifest.json (skipping *.IGNORE.md files)
    • If new rapports found: writes a rapport_review trigger to scrum_triggers.jsonl
  3. Always writes a status_review trigger for the next Scrum Master session
  4. If .session_handoff.json exists in the queue: forwards the handoff to the developer trigger queue

This ensures the Scrum Master always has an up-to-date view of the project when it starts the next session.

hooks/distribute-changes.sh

Distributes workflow files to all consumer projects registered in .jenga_paths.
