Switching between Claude Code, Cursor, Codex, Copilot, or Windsurf? Paste your agent config and convert it in one click, correct filename, conventions, imports, and frontmatter, with notes on exactly what changed.
Paste a config on the left, pick the target format, and the converted file appears here with placement notes.

Every AI coding tool reads project instructions from a file, they just disagree on what to call it. The content is ~95% identical, which is why conversion is one click.
Claude Code's memory file, loaded every session. Unique power: @path/to/file.md imports that pull other docs in automatically.
The emerging open standard, read by OpenAI Codex, Cursor, Google Jules, Zed, and more. If you pick one canonical file, pick this.
Legacy .cursorrules (single file, deprecated) and modern .cursor/rules/*.mdc with frontmatter for glob-scoped, always-on, or agent-requested rules.
.github/copilot-instructions.md for GitHub Copilot; .windsurfrules for Windsurf's Cascade agent. Same markdown, different mailbox.
It's the format with the broadest native support, so write your real instructions there once. Every other file becomes a thin pointer.
Claude Code supports imports, so your whole CLAUDE.md can be @AGENTS.md, zero duplication, and Claude still gets its native file.
Instead of one giant rules file, split Cursor rules into .cursor/rules/*.mdc files with globs so frontend rules only load for frontend files.
Duplicate files rot fast, a rule fixed in one file and not the others causes the exact inconsistent behavior these files exist to prevent. Convert, don't copy-paste.
@AGENTS.md, and Claude imports the standard file automatically..cursor/rules/*.mdc system. Use .mdc when you want rules scoped to specific globs or triggered on request.@path/file.md as a normal markdown link and tells you it did. Other tools won't auto-load the referenced file, but the pointer keeps the information discoverable.A great AGENTS.md is step one.
