Fair question. Pydantic.ai looks like a wrapper around the client and closer to an agent framework. agents.json is not that.
agents.json makes an existing API format like OpenAPI, interpretable to LLMs. This is done through tool selection and workflow creation.
For example, someone here mentioned the large Twilio API was hard to manage with an LLM. We could write a Twilio agents.json to bundle API calls into outcome-based workflows, and create a searchable collection that lets us get higher accuracy on tool selection.
