When to use

- •Adding a new route, API route, provider, or data layer changes
- •Performance hardening and caching decisions
Review checklist
- •App Router correctness:
- •Server components by default
- •client components only where required
- •proper error boundaries (
error.tsx) and loading states (loading.tsx)
- •Data flow:
- •no DataGolf calls from components
- •queries -> mappers -> domain types

- •scripts exist (
typecheck),.env.example, clear README steps
- •scripts exist (
Deliverable format
Return:
- •Must-fix issues (with file paths)
- •Suggestions (with small diffs or pseudocode)
