PR Post-merge Cleanup

Trigger

• The task requester explicitly says "cleanup after merge" or "clean up the task."
• This SKILL is invoked directly.

Preconditions

• The target PR is actually merged on GitHub: gh pr view {number} --json state,mergeCommit.
• The task requester approved Issue close, or the PR body included closes #N and the Issue was automatically closed.

Procedure

1. Check PR and Issue state.

   gh pr view {number} --json state,mergedAt,mergeCommit,headRefName
   gh issue view {N} --json state

• If PR state != MERGED, stop immediately and report to the task requester.

1. Close the Issue only if it was not already closed.

   gh issue close {N}

1. Update {BASE_BRANCH}.

   git fetch origin --prune
   git checkout {BASE_BRANCH}
   git pull --ff-only

1. Delete the remote publish branch. Skip if the branch was already deleted by PR merge with --delete-branch.

   git push origin --delete publish/task{N} 2>&1 || echo "already deleted"

1. Remove the separate worktree if one was used.

   git worktree remove ../{repo}-task{N}
   git worktree prune

1. Delete the local work branch only when it is no longer needed.

   git branch -d local/task{N}
   # Forced deletion requires explicit task requester approval: git branch -D local/task{N}

1. Final daily task board check: confirm the #{N} row in mydocs/orders/{yyyymmdd}.md is Done with a completion time.
2. Report the cleaned items briefly to the task requester.

Verification

• gh pr view {number} shows state == MERGED.
• git branch -vv | grep local/task{N} has no output if the branch was deleted.
• git ls-remote origin publish/task{N} has empty output.
• git worktree list does not include the cleaned worktree.
• git branch --show-current is {BASE_BRANCH}.

Never Do

• Close an Issue when the PR is not merged.
• Delete another task branch or the main worktree.
• Run git branch -D without explicit approval; unmerged commits may be lost.
• Delete another worker's stash.
