bmad-checkpoint-preview

Trigger the checkpoint review with a PR reference, branch, or commit. The skill resolves the change, summarizes its intent and diff stats, then walks you through concerns, risk spots, and testing suggestions before you decide to approve or request rework.

It groups changes by design concern rather than by file, ordering stops so each builds on the previous one. Each stop is a clickable path:line reference with a short framing phrase, targeting two to five concerns per change.

The skill generates a review trail from the diff itself by reading changed files and identifying two to five concerns with key path:line stops. If git is unavailable and no trail can be built, it falls back to a non-trail walkthrough mode.

Yes. During the detail pass you can say "dig into [area]" and the skill switches to correctness mode, reading the relevant code in full context to check edge cases, error handling, race conditions, and boundary conditions.

No. It assumes CI and test suites already exist and focuses on human judgment: design evaluation, risk awareness, and manual observation of behavior that automated checks cannot provide.
