Cursor Rules

What it does

Cursor's rules feature gives the Agent persistent instructions. Project rules are .mdc files in .cursor/rules, and there are also User Rules, Team Rules and plain AGENTS.md files.

Who it's for

Cursor users who are tired of repeating the same instructions every chat.

How to set it up

1. Type /create-rule in Cursor's Agent chat and describe the rule, or add one from Customize → Rules → Add Rule.

2. Rules are saved as .mdc files in .cursor/rules (plain .md files there are ignored). Commit them to git. Example rule:

   markdownCopy

   ---
   globs: src/components/**/*.tsx
   alwaysApply: false
   ---
   
   - Use named exports, not default exports

3. Pick how each applies: Always Apply, Apply Intelligently (by description), Apply to Specific Files (globs), or Apply Manually (@-mention). Keep each under ~500 lines.

Check the official docs for the latest steps.

Example prompts

/create-rule Use named exports and Tailwind for all components in src/components.

Following our project rules, create a new API route for user settings.

Write an AGENTS.md for this repo based on package.json and the folder structure.
