Review Implementation

Point it at your markdown specs or PRD and it'll trace every requirement to actual implementation, flag what's missing, what's half-done, and what you overbuilt. It runs a methodical nine-pass audit covering correctness, integration, security, performance, and cleanup. You can use it in review-only mode to get findings with file and line evidence, or ask it to fix and it'll make targeted changes without scope creep. The workflow is thorough without being precious: it reads your docs, inspects the relevant surfaces, builds a traceability map, then either reports or repairs. Honest take: if you work from written specs, this closes the loop between what you said you'd build and what you actually built.
