I've came across llms.txt files in few services. I don't know how the agents.md compares to the llms.txt files, but I guess they could pretty much have the same content. See more also here https://llmstxt.org/
Anyhow, I have made few interesting observations, that might be true for the agents.md also:
Agents have trouble with these large documents, and they seem to miss many relevant nuances. However, its rather easy to point them to the right direction when all relevant information is in one file.
Another thing is that I personally prefer this style of documentation. I can just ctrl+f and find relevant information, rather than using some built in search and trying to read through documents. I feel that the UX of one large .txt file is better than the documentation scattered between multiple pages using some pretty documentation engine.
