# .cursorrules ## Stack - Primary language: TypeScript ## Conventions - Match existing file structure and naming before introducing new patterns. - Prefer composition over inheritance. - Keep functions small and single-purpose. ## Style - No unnecessary comments — code should be self-explanatory through naming. - No unused imports or dead code left behind. - Follow the existing formatting in the file being edited (indentation, quote style, semicolons). ## Avoid - Don't add new dependencies without a clear reason. - Don't refactor unrelated code while fixing a bug. - Don't change public function signatures without checking all call sites. ## Before finishing - Re-read the diff for anything unrelated to the requested change. - Make sure the change compiles / type-checks before declaring done.
Why a rules file beats repeating yourself in every prompt
Without a rules file, you end up re-explaining your stack and conventions every session — and the AI still drifts back to its defaults the moment you stop reminding it. A .cursorrules file makes those defaults yours instead.
Keep it short. A rules file with 40 vague rules gets skimmed and ignored the same way a 40-page onboarding doc does. Five specific, enforceable rules beat twenty aspirational ones.
