ucp.config.json and generates a phased implementation plan. - Code Scaffolding & Gap Analysis: Generates TypeScript types, Zod schemas, API routes, and discovery profiles, and uses AST-based analysis to find gaps between existing checkout code and UCP requirements. - Validation & Testing: Validates implementations against UCP schemas, generates the /.well-known/ucp discovery profile, and produces unit tests for handlers. - Use Case: A merchant running a Next.js store wants to expose a UCP-compliant checkout over REST and MCP. They run /ucp init, answer the consultation questions, scaffold the full implementation, and validate it against the spec. ## Quick Start Ask the assistant to run /ucp init to clone the UCP specification and create the initial configuration for this project.High-intent search queries and answers about installing and using this skill.
Run /ucp init to clone the spec and create ucp.config.json, then /ucp consult to answer qualifying questions. Follow with /ucp plan and /ucp scaffold to generate compliant checkout endpoints, types, and schemas.
UCP supports REST, MCP (Model Context Protocol), A2A (Agent-to-Agent), and embedded iframe checkout transports. You select which to enable during consultation, and the config records a transport priority order.
No, Edge runtime is not supported for UCP implementations. The skill enforces Node.js as the default runtime, with Bun available as an opt-in alternative, and marks generated routes with runtime = 'nodejs'.
Run /ucp gaps to perform AST-based analysis of your existing API routes and checkout logic. It produces a report classifying findings as critical gaps, partial implementations, or compliant areas against UCP requirements.
It is a JSON endpoint that advertises your UCP version, services, capabilities, and payment handlers to agents and platforms. The /ucp profile sub-command generates it from your ucp.config.json settings.
Generated code requires zod for schema validation and uuid for session IDs. The jose package is added when AP2 mandate signing or webhook JWS signing is enabled in the configuration.
