Q: What is a Cursor .mdc rule?

A Markdown file in .cursor/rules/ with a small front-matter block (description, globs, alwaysApply) that controls when Cursor applies it.

Q: Where does Copilot read instructions from?

.github/copilot-instructions.md for repo-wide instructions, plus .github/instructions/*.instructions.md files scoped with applyTo globs.

Paste your existing CLAUDE.md, AGENTS.md, .cursorrules or Copilot instructions. Get a correct file for every agent.

Your rules (Markdown)

Cursor rule description Globs (optional)

CLAUDE.md imports AGENTS.md (one source of truth)

Frequently asked questions

Do I need a separate rules file for every agent?

Not always. Codex, Cursor and Copilot read AGENTS.md. Claude Code reads CLAUDE.md, so many teams keep AGENTS.md as the source and add a CLAUDE.md that imports it with @AGENTS.md.
