- Cursor uses
.cursor/rules - OpenAI uses
AGENTS.md - Claude uses
CLAUDE.md - The list goes on…
Whilst these text based instructions are fantastic for hosting in a repo, how can we account for multiple developers working in the same repo but using different AI tools?
If I had to vote for an existing route, I think AGENTS.md is the most elegant.
If I could offer my own implementation, I think .agents/rules.md would be better. That way we could establish a canonical folder that holds the likely-to-grow list of reference files and docs we’ll be providing to AI agents in the future.
