When you're done coding and tests pass, this walks you through the four ways to wrap up: merge locally, push a PR, leave it alone, or discard the work. It verifies tests first, won't let you proceed if anything's broken, and handles git worktree cleanup automatically for the merge and discard paths. The four-option structure keeps things moving without getting stuck in "what now?" conversations. Pairs naturally with subagent-driven-development and executing-plans skills that call it when their work finishes. One nice touch is the typed confirmation requirement before discarding work, which prevents accidental deletions when you're moving fast.
