What it is, and how people use it
Configuration files that enhance Cursor AI editor experience with custom rules and behaviors It sits on the Cursor Rules shelf of the catalog, maintained by @PatrickJS.
✓Drop-in for Claude Code, Codex CLI and Cursor - install and it just runs.
✓Read the SKILL.md / README first; most setups are one command from the docs.
✓Teams use it to standardise how agents behave across every repo in the org.

The editor stops relearning your stack
Rules encode your framework choices, folder layout and TypeScript style once. Every new chat starts already knowing how your project is built.
Review-ready diffs by default
Enforce tests, formatting and typing at the prompt level and the agent's pull requests arrive shaped like your team's, not like a tutorial's.
Near-zero cost to adopt
It is plain text checked into .cursor/rules. No runtime, no account, no server - and the file doubles as documentation for humans.
Portable across agents
The same rules files increasingly work in Windsurf, Copilot and Claude Code. A convention you write once pays off on every tool you try next.
