Select and read the existing guidance for the user’s task. Product documentation describes what an extension can do; implementation guides describe how to build it. Before recommending an extension or writing code, load the applicable bundled reference files as well as the relevant product documentation. A link or filename in this skill isn’t a substitute for reading its contents.
For a capability question, check native Stripe features and the documented applicability and limitations of the extension. For an implementation request, create or modify working files using the selected guide. For an existing app, inspect its manifest, packages, installed SDK, and local agent instructions before deciding what to change.
Use information already supplied by the user or existing app. Read <references/discovery.md> when you need to clarify the app’s requirements, and <references/extension-types.md> for an overview of app architectures. Ask only for missing information that affects the task.
Use these existing product documents to determine which capability fits and whether the account has the required access. Don’t infer support from an extension’s name or the existence of a scaffold.
| Task | Read |
|---|---|
| Select an extension interface and its supported implementation types | Extension points (opens in a new tab) and how extensions work (opens in a new tab) |
| Change how items are included on subscription invoices | Item handling extensions (opens in a new tab) |
| Customize prorations | Native proration behavior (opens in a new tab) and prorations extensions (opens in a new tab) |
| Apply customer balances | Customer balance extensions (opens in a new tab) |
| Calculate discount amounts | Discount calculation extensions (opens in a new tab) |
| Add an action to Stripe Workflows | Existing workflow actions (opens in a new tab), existing custom actions (opens in a new tab), and how custom actions work (opens in a new tab) |
| Customize another product’s behavior | Follow the selected interface’s product documentation from the extension-point catalog |
The references/*.md files are bundled with this skill. After selecting the capability, load the applicable files before following their links to supporting documentation. Combine rows when an app needs multiple types. Follow the selected guide’s prerequisites, scaffolding, testing, and debugging instructions.
| Task | Read |
|---|---|
| Build or modify any Dashboard UI, including drawers and full-page apps | <references/ui-extensions.md>, then each selected component’s current API documentation |
| Author, test, or debug a script extension | <references/script-extensions.md>, then the selected extension point’s implementation guide |
| Build a custom-action script | <references/script-extensions.md> and build a custom action with a script (opens in a new tab) |
| Build a custom-action remote function | Build a custom action with a remote function (opens in a new tab) |
| Build a self-hosted UI back-end or webhook service | <references/backend.md> and <references/authentication.md>; also load <references/webhooks.md> when receiving Stripe events |
| Store app credentials with the Secret Store API | The Secret Store API section in <references/backend.md> and store secrets (opens in a new tab), including for apps without a self-hosted back-end |
| Look up APIs, SDK patterns, configuration, or additional extension documentation | <references/canonical-docs.md> |
Use the UI reference for layout and composition, and current component documentation for import paths, props, and styling APIs. For scripts and remote functions, follow the selected extension’s documentation; UI and self-hosted back-end instructions don’t define their runtime capabilities.
Read these references when the corresponding task is needed. Reuse existing apps and packages; scaffold only what is missing.
| Task | Read |
|---|---|
| Scaffold, build, test, preview, or upload an app | <references/workflow.md>, together with the selected implementation guide |
| Choose authentication for access to Stripe APIs | <references/authentication.md> |
| Receive Stripe events | <references/webhooks.md> |
| Build a first-run setup experience | <references/onboarding-ux.md> and the UI reference |
| Release versions, change installed permissions, or publish to the marketplace | <references/publishing.md> |
| Submit feedback after running app toolchain commands | <references/feedback.md> |
references/, then open those files with a file-reading tool before starting the corresponding work. For example, UI with a self-hosted back-end needs both UI and back-end guidance; onboarding also needs the UI reference.references/ paths relative to this skill’s directory and bare reference filenames relative to its references/ directory. When reading the hosted skill, fetch the corresponding reference URLs relative to the skill URL.stripe docs when available, including for pages that require account access.Build, modify, or review Stripe Apps and extensions using the relevant documentation and reference guides. Use for custom Stripe Dashboard UI, stripe-app.yaml, @stripe/ui-extension-sdk, @stripe/extensibility-sdk, script extensions, extension interfaces, custom workflow actions, and apps that authenticate to Stripe or react to events. Also use when deciding whether a Stripe extension can support the user's billing or workflow requirements.
