Checks Active Record boundaries, migration risk, controller shape, callbacks, and test coverage.
Add-onModular pull request review
Start with a reviewer. Extend it with specialists.

Current status
Marketplace prototype first. Review engine later.
The current GitHub App is still a prototype shell for Marketplace validation. It does not inspect repository contents, store customer code, call external AI services, or post review comments.
The product direction is to sell a base reviewer with optional expert extensions. Production review features will require updated permissions, disclosures, and documentation before launch.
