Celebrate — post-task wrap-up

[Execute → Celebrate]

Run after the branch has been merged. Do not skip steps.

Pre-check

Verify the branch has been merged before proceeding:

git fetch origin && git merge-base --is-ancestor HEAD origin/main

If the current branch is not merged into origin/main, stop and tell the user. Do not continue with celebrate.

Reflect and update

1. Reflect: what worked, what didn't, what was surprising.
2. Log to telemetry: pipe a JSON summary to ~/.claude/skills/celebrate/log-celebration:

   echo '{"project":"<name>","branch":"<branch>","commits":<n>,"files_changed":<n>,"ticket":<number|null>}' | ~/.claude/skills/celebrate/log-celebration
   

   Then write the current HEAD SHA to the sentinel:

   git rev-parse HEAD > "$(git rev-parse --git-common-dir)/celebrate-last-sha"
   

3. Sweep for similar patterns: review the fix just completed. Grep/audit the codebase for the same anti-pattern in other files. File tickets for all instances found.
4. Guard against regression: if the sweep above was juicy — multiple instances of the same anti-pattern — the bug has a class shape. File a follow-up ticket for a standing regression test covering the class. Do not auto-write the test, do not bundle it into the fix PR. If the sweep found nothing, move on silently. /verify is a per-PR gate; a standing test is what catches the class coming back in an unrelated future PR.
5. Update project docs if pipeline, data contract, or methodology changed.
6. Save persistent memory: durable lessons from this task. No sweep here — sweeps happen at /end-session.

Close and clean up

7. Close the ticket if still open.
8. Check for tracking ticket: if the closed ticket has a parent, check whether all sibling sub-tickets are now closed.
   • All closed → integration review: re-read all child diffs, run full test suite, verify exit criteria.
   • Any open → do nothing, tracker stays open.
9. Exit worktree (if in one): call ExitWorktree with action remove. Skip if not in a worktree.
10. Verify hygiene:
    • git branch -a → no stale remote branches
    • Check for stale merge requests
11. Offer to improve workflow rules if lessons were learned.

Note: STATE.md is updated on main during /end-session, not here.
