.cursorrules for a strict TypeScript + React codebase

A tuned .cursorrules file that keeps Cursor's agent on-convention: strict types, no dead code, match existing patterns.

Open in Studio
Prompt
Generate a `.cursorrules` file for a TypeScript + React + [framework] project. The rules should make the AI:

- Match existing file structure, naming, and import style before writing anything new; read neighboring files first.
- Never use `any`; prefer precise types and discriminated unions. No non-null `!` unless justified in a comment.
- Keep components small; extract logic into hooks/utils. No inline business logic in JSX.
- Never add dependencies without asking. Prefer the standard library and existing utils.
- No comments that restate code; only explain non-obvious 'why'.
- Accessibility: semantic elements, labels for icon buttons, visible focus.
- When unsure, ask a single clarifying question instead of guessing.

Output only the `.cursorrules` file contents.
