Jules uses AGENTS.md, which indicates that Google is on board with it as the standard. If Gemini Code Assist continues to be a thing (I'm not sure whether Jules is intended to succeed it) then presumably it will support AGENTS.md as well. In the meantime you can configure Gemini Code Assist to use an arbitrary filename.

I don't see a reference to a specific filename in Aider's documentation, can you link to it?

Anthropic appears to be the major holdout here.
