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