close-spec
Most recent maintenance signal among this shortlist.
| Signal | close-spec When a spec under specs/<feature>/ is done shipping (a write-spec build, or any planned task that produced a spec), archive it to specs/done/ and rewrite it from a build-plan into a durable rationale — the why, the principles, the invariants — pointing back to the real code for the how. Use when implementation has landed and the plan no longer matches what shipped, or the user says a feature/spec is finished. Pairs with [write-spec](../write-spec/SKILL.md) (the plan this closes) and [review](../review/SKILL.md) (run before closing). | Implement Implement work from an approved spec or ticket set, run focused and full tests, invoke code review, and commit the result to the current branch. | Code Review Review a branch or diff against repository standards and the originating spec in two independent analysis passes. |
