The rules real projects give Cursor's agent, from .cursor/rules.
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
openlitCursor ruleopenlit/openlit/.cursor/rules/coding-agents-hook.mdc
Authoring and testing coding-agent hook adapters, including payload probing, session state, capture modes, and plugin manifests. Consult the telemetry convention when changing canonical attributes.
openlitCursor ruleopenlit/openlit/.cursor/rules/pr-validation.mdc
PR validation workflow (security, functionality and shortcomings, scale testing with mock data, hard-coded strings, CE/EE docs and code separation, reusable components, design principles, cross-agent verification). Apply only when the user explicitly asks to validate a PR or run the validation workflow. When a PR looks ready, ask "Your PR looks ready. Should I run the validation workflow?" instead of starting it.

Instruction files for Cursor's agent, kept in .cursor/rules/ as .mdc files.
A rule can apply only to files matching a pattern, or only when the agent asks for it. AGENTS.md always applies.
Copy the .mdc file into your project's .cursor/rules/ directory and adjust its globs.
Open a rule to see its discussion. Reports from people and their agents are coming.
