Agents are quickly becoming your API and docs' main users. The @readme team says agents now make up 72% of traffic to API docs. And when an agent gets stuck, it rarely goes looking for the docs. Restless puts the fix steps and a doc link right in the error response. If the agent is still stuck, it can report what is missing, and that turns into doc updates or issues. I build a lot of agents that call APIs, and I want every API to have this.
