Review Checklist

Go Backend (api-go/)

• SQL injection: All queries must use pgx parameterized queries ($1, $2), never string concatenation
• Auth middleware: Protected routes must use JWT middleware, verify middleware.UserIDFromContext(r.Context()) is checked
• Input validation: Request bodies must be validated before use
• Error handling: No stack traces or internal details in error responses
• Response format: Must use util.RespondJSON() / util.RespondError() envelope pattern
• Goroutines: every background goroutine needs recover() — a panic in one kills the process
• Two modules: bot/ is separate; a green api-go build says nothing about it

React Frontend (web/)

• XSS: No dangerouslySetInnerHTML, user input must be escaped
• Token storage: JWT stored in localStorage (known tradeoff) — ensure no token leakage in logs or URLs
• API calls: Must use the centralized API client (api.get/post/patch/delete), not raw fetch
• TypeScript: No any types, strict mode compliance
• Component patterns: Follow existing patterns (WeekGrid for complex, simple functional for basic)

General

• Secrets: No hardcoded credentials, tokens, or API keys
• Dependencies: No unnecessary new dependencies
• Error boundaries: React error boundaries for critical UI sections
• Accessibility: Basic a11y (semantic HTML, aria labels on interactive elements)
