If robots.txt is an exclusion file, I can't help but wonder if we just need an agents.json inclusion file in the root to get a "standard" started.
A2A looks like a typical enterprise, authenticated, strict DTD style spec.
Agents acting on behalf of consumers need a simple file that describes:
1) What services are provided
2) What tools are available and how to use them
Agent behavior and actions should happen in latent space. The format of any spec is almost meaningless, as long as it's self describing and conveys those 2 points.
