CLAUDE.md vs AGENTS.md

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.
