Report #97823

[architecture] What contract should my API expose so AI agents can discover and invoke its capabilities?

Design agent-facing APIs around an OpenAPI 3.x schema published at a stable URL. Treat operationId, summaries, and descriptions as part of the prompt surface, and version the schema explicitly.

Journey Context:
Agents do not browse API docs; they need a machine-readable contract. OpenAPI is the de facto standard for ChatGPT actions and many tool-calling frameworks. The design tradeoff is rigor: every parameter must be typed, every endpoint described, and changes must be versioned because agent prompts are brittle. Ad-hoc REST or prose documentation fails here because the agent cannot reliably map natural language intent to endpoints. Start with the schema, generate code or docs from it, and never treat it as an afterthought.
