# Review Design · sontek

> Architectural / design review of EXISTING code at module scope — coupling, abstraction depth, seams, testability, scalability. Routes the code through the senior-engineer agent (and product-manager when it has user-facing surface) and returns a verdict plus prioritized concerns. Use when asked to "design review this module", "architectural review of this code", "is this module well-designed / too coupled", "review the design of X", "will this service scale", or "put your senior-engineer hat on" over a module or package. Distinct from review-code (diff-scoped bug/security/perf finders), review-plan (reviews a planning doc, not code), and improve-architecture (explores the whole codebase and proposes new designs as RFCs — generative, not evaluative).
