I completely agree with you. There was a recent finding that said Agents.md outperforms skills. I'm old school and I actually see best results by just directly feeding everything into the prompt context itself.

How do you shut off particular api calls with an agents.md?

I personally use tool calling for APIs, so really not sure (I don't use agents.md per se, I directly stuff info into the context window)
