API docs that tell callers what each field means.
Guides the creation of exhaustive machine-interface documentation that explains wire formats and behavior to callers.
When to use it
Use when documenting interfaces machines call or parse, including endpoints, messages, webhooks, commands, and file formats; exclude internal code interfaces and configuration references.
It changes how the agent writes machine-interface reference documentation in the project, documenting existing contracts rather than judging their design.
What you provide
