Apply when creating or modifying manifest.json, service.json, or node/package.json in a VTEX IO app. Covers builders (node, react, graphql, admin, pixel, messages, store), policy declarations, dependencies, peerDependencies, and app lifecycle management. Use for scaffolding new VTEX IO apps, configuring builders, or fixing deployment failures related to app structure and naming conventions.
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.
Apply when designing or modifying a VTEX IO storefront theme app — the app that owns `store/blocks.json`, `store/routes.json`, `store/templates/`, `store/contentSchemas.json`, and the storefront page tree assembled from `store.home`, `store.product`, `store.search`, `store.custom`, and other native page templates. Covers how a theme app extends a base theme, declares routes, composes blocks across pages, and how its `store/` files relate to merchant Site Editor content. Use for theme scaffolding, custom page routes, theme-level overrides, or reviewing whether a change belongs in the theme app, in a component app, or in app settings.
Apply when building or debugging a VTEX IO session transform app (vtex.session integration). Covers namespace ownership, input-vs-output fields, transform ordering (DAG), public-as-input vs private-as-read model, cross-namespace propagation, configuration.json contracts, caching inside transforms, and frontend session consumption. Use when designing session-derived state for B2B, pricing, regionalization, or custom storefront context.
Apply when controlling access to VTEX IO app resources using role-based or resource-based policies. Covers policies.json for role-based access control, service.json policies for resource-based access, VRN syntax for principals, the difference between app-to-app and user/integration access, and GraphQL @auth directives. Use when deciding how to secure routes and restrict which apps, users, or integrations can access your endpoints.
Apply when working with MasterData v2 entities, schemas, or MasterDataClient in VTEX IO apps. Covers data entities, JSON Schema definitions, CRUD operations, the masterdata builder, triggers, search and scroll operations, and schema lifecycle management. Use for storing, querying, and managing custom data in VTEX IO apps while avoiding the 60-schema limit through proper schema versioning.
Apply when connecting React components to Store Framework blocks and render-runtime behavior in VTEX IO. Covers interfaces.json, block registration, block composition, and how storefront components become configurable theme blocks. Use for block mapping, theme integration, or reviewing whether a React component is correctly exposed to Store Framework.
Apply when designing VTEX IO configuration apps with the configuration builder or when a service app must receive structured configuration through runtime context. Covers the separation between service apps and configuration apps, schema.json and configuration.json, settingsType, and reading injected configuration through ctx.vtex.settings. Use for shared service configuration, decoupled configuration lifecycle, or reviewing whether app settings should be replaced by a configuration app.
Apply when defining service.json routes, choosing public vs segment vs private URL prefixes for VTEX IO services, or setting HTTP cache headers that interact with the VTEX edge and CDN. Covers path patterns, cookie visibility, edge caching behavior, and aligning Cache-Control with data sensitivity. Use for Node or .NET IO backends where request path and response headers determine CDN safety.
Apply when improving VTEX IO Node or .NET services for latency, throughput, and resilience: in-process LRU, VBase, stale-while-revalidate, AppSettings loading, request context, parallel client calls, and avoiding duplicate work. Covers application-level performance patterns that complement edge/CDN caching. Use when optimizing backends beyond route-level Cache-Control.
Apply when installing, publishing, upgrading, or rolling back a VTEX IO storefront theme app (`vendor.store-theme` or any app that owns `store/blocks.json`, `store/routes.json`, and `store/contentSchemas.json`). Covers how Site Editor and theme content are scoped by the app's MAJOR version, why a major version bump leaves the new major with no merchant content and silently falls back to default theme content, the safe install-in-workspace, migrate- content with the `updateThemeIds` mutation, smoke-test, then promote workflow, the 3-way mine-wins merge that `vtex workspace promote` performs against `vtex.pages-graphql` VBase (with automatic per-minute `userData_backup` snapshots when conflicts are resolved), and the support-led recovery path. Use for any operation that changes which version of a content-holding app is installed in `master`.
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.
