• Never use IIFEs in React components.
• Always prefer easy-to-read code over clever code.
• Don't run the dev server unless there's a specific reason to do so. I typically run it myself outside Claude.
• Never add extraneous comments or comment markers to generated code. Code should be self-documenting.

TypeScript

• Prefer type over interface unless extending or declaration merging is needed.
• No ! non-null assertions without a comment explaining why it's safe.
• Prefer unknown over any and narrow with type guards.
• Use const assertions (as const) for literal types.

React / Next.js

• Never use useEffect for derived state. Use useMemo instead.
• Always provide complete dependency arrays. Never disable exhaustive-deps without discussion.
• Prefer server components unless client interactivity is required.
• Use "use client" directive only at the component that needs it, not higher.
• Use forwardRef for components that wrap DOM elements.
• Always support className prop for composition with cn().

Testing

• When implementing a feature, ask if I want tests before writing them.
• Prefer integration tests over unit tests for UI components.
• Test user behavior, not implementation details.

Before Finishing

• Mention if lint/typecheck should be run to verify changes.
• Note any manual verification steps needed (browser testing, etc.).
