resume-project rebuilds context from the project's own records and hands back a briefing — deliberately stopping there rather than resuming the work itself.

smoke-verify closes the gap a clean compile leaves open: undefined references survive a build and crash at runtime, so the verdict rests on observed evidence, not a green exit code.

ship runs the settled finish flow — preflight gates, squash-merge to main, push, delete the branch — and treats a deploy as unconfirmed until it is observed live.

refine-skill closes the loop on the tooling itself, turning a session where a skill misfired into proposed before→after diffs you approve before anything changes.
