One reason to consider is around context usage with LLMs. Less is generally better and README.md files are often too much text some of which I don’t want in every context window.

I find AGENT.md and similar functioning files for LLMs in my projects contains concise and specific commands around feedback loops such as testing, build commands, etc. Yes these same commands might be in a README.md but often there is a lot more text that I don’t want in the context window being sent with every turn to the LLM.
