Component Review Rubric Reference

Apply the shared Component Review Rubric before approving React components, then run the React-specific checks below.

Anti-Patterns

• Fetching everything in client effects by default: Server-first data loading is usually simpler, faster, and easier to cache.
• Adding memoization before profiling: Manual optimizations can create stale-prop bugs and hide simpler design fixes.
• Skipping keyboard and accessible-name review: A component is not done if only pointer users can operate it reliably.
