AGENTS.md
https://agents.md/
A README equivalent for agents. Finally, a standard for a markdown file where we write context and additional instructions for an AI coding agent. This is a simple text file. It will also be useful for human developers, because most people barely write anything in their READMEs anymore, but that won't work here. This is because LLMs require greater detail and precision.

Previously, if I used several AI coding tools in a repository, I had to have a separate file for each, and also think about how to synchronize them. Now, only AGENTS.md in the project root is sufficient. It is possible to create separate files for subdirectories.

Already supported: OpenAI Codex, Amp, Jules by Google, Cursor, Factory, RooCode, Aider (via config), Gemini CLI (via config), Kilo Code, OpenCode, Phoenix, Zed.
