agent-api-design

Expert in designing APIs, CLIs, and documentation systems for AI agent consumers. Use when building or reviewing interfaces intended to be used by LLM agents rather than humans — APIs, CLIs, SDKs, skills/docs, synchronization strategies, and concurrency models. Use when the user says "design an agent API", "make my API agent-friendly", "build a CLI for agents", "design skills/docs for agents", "agent interface review", or "how should agents use my product".
