vtex-io-app-structure
App Architecture & Manifest Configuration
When this skill applies
Use this skill when working with the foundational structure of a VTEX IO app — the manifest.json file, builder system, policy declarations, dependency management, service.json resource limits, and app lifecycle (link, publish, deploy).
- Creating a new VTEX IO app from scratch
- Adding a builder to an existing app
- Configuring policies for API access
- Troubleshooting deployment failures related to manifest misconfiguration
Do not use this skill for:
- Backend service implementation details (use
vtex-io-service-appsinstead) - React component development (use
vtex-io-react-appsinstead) - GraphQL schema and resolver details (use
vtex-io-graphql-apiinstead)

headless-checkout-proxy
Apply when implementing cart, checkout, or order placement logic proxied through a BFF for headless VTEX storefronts. Covers OrderForm lifecycle, cart creation, item management, profile/shipping/payment attachments, orderFormId management, and secure checkout flows. Use for any headless frontend that needs to proxy VTEX Checkout API calls through a server-side layer with proper session cookie handling.
1vtex-io-masterdata
Apply when working with MasterData v2 entities, schemas, or MasterDataClient in VTEX IO apps, or when anyone designing or implementing a solution must scrutinize whether Master Data is the correct storage. The skill prompts hard questions: native Catalog or other VTEX stores, OMS, or an external database may be better; do not default to MD because it is convenient. Covers JSON Schema, CRUD, triggers, search and scroll, schema lifecycle, purchase-path avoidance, single source of truth, and BFF handoffs. Use for justified custom persistence while avoiding the 60-schema limit.
1vtex-io-app-settings
Apply when defining, validating, or consuming VTEX IO app settings. Covers settingsSchema, app-level configuration boundaries, and how backend or frontend code should depend on settings safely. Use for merchant-configurable behavior, settings forms, or reviewing whether settings belong in app configuration rather than hardcoded logic or custom data entities.
1vtex-io-service-runtime
Apply when designing or implementing the runtime structure of a VTEX IO backend app under node/. Covers the Service entrypoint, typed context and state, service.json runtime configuration, and how routes, events, and GraphQL handlers are registered and executed. Use for structuring backend apps, defining runtime boundaries, or fixing execution-model issues in VTEX IO services.
1vtex-io-admin-react
Apply when building VTEX IO admin-facing React interfaces under the admin builder. Covers VTEX Styleguide and Shoreline usage, admin page composition, data-heavy admin interactions, and keeping administrative interfaces consistent with the VTEX Admin environment. Use for settings pages, moderation tools, dashboards, or operational UIs inside VTEX Admin.
1vtex-io-react-apps
Apply when building React components under react/ or configuring store blocks in store/ for VTEX IO apps. Covers interfaces.json, contentSchemas.json for Site Editor, VTEX Styleguide for admin apps, and css-handles for storefront styling. Use for creating custom storefront components, admin panels, pixel apps, or any frontend development within the VTEX IO react builder ecosystem.
