This seems way too complicated and unnecessary. Agents are perfectly capable of discovering memories on the FS, following agent instructions.

I guess this adds indexing and querying but most coding agents have good solutions for this already, and it works automagically for everything, not just memories.

What we could use instead is a file system layout standard, which could subsume memories and a lot more. I don't think that's needed either, but it would probably solve more problems than this.
