   AI First CLI · yzfly bundle

   This skill should be used when designing, building, or reviewing a command-line tool that AI agents will call, not just humans. Use it when deciding output format (JSON vs text), error handling, exit codes, flags, discoverability, dependencies and packaging, or autonomous-operation safety for a CLI. Also use it when asked how to make an existing CLI agent-friendly, or to evaluate a tool against the agent-first design philosophy. Grounded in Vercel's cloud-for-agents methodology.
