What problem does it solve? Building a Stripe App involves many moving parts — the stripe-app.yaml manifest, sandboxed UI extensions, backend authentication, webhooks, and marketplace publishing — and getting any of them wrong produces broken apps. This Skill guides an agent through the full development workflow so the user ends up with complete, runnable files on disk. ## Core Features & Use Cases - Guided discovery and architecture routing: A structured interview maps the user's goal to the right extension type (UI extension, backend-only, full-stack, extension interfaces) and the correct Dashboard viewport. - Full build workflow enforcement: Scaffolds with stripe generate app, writes complete files to disk, and walks through build, test, preview, upload, and install steps with hard rules against common failure modes. - Canonical docs grounding: Requires fetching current Stripe documentation before writing code, covering authentication types, webhooks, Secret Store, UI components, and publishing. - Use Case: A user says "add a panel to the customer page showing loyalty points." The Skill asks discovery questions, scaffolds the app, writes the UI extension and backend, and delivers the exact CLI commands to preview and publish it. ## Quick Start Ask the agent to build a Stripe App that shows custom data next to a customer in the Stripe Dashboard, and answer its four discovery questions.
