Ui Designer

MUST activate when a uiBundles/*/src/ project does ANY Salesforce record operation — reading, creating, updating, deleting, or caching/refreshing query results. Triggers: code importing @salesforce/platform-sdk, calls to sdk.graphql.query / sdk.graphql.mutate / sdk.fetch, *.graphql files, stale data needing a force-refresh, or wiring up a UI bundle's data layer to read, write, or refresh Salesforce records. The default for new read/write work is the Read/Write workflow with the current @salesforce/platform-sdk API; only follow the migration path when EXISTING code already uses the old @salesforce/sdk-data callable form. Not for building app shell/UI, styling, file upload, or auth/search scaffolding — use the other ui-bundle-* skills. DO NOT TRIGGER when: OAuth setup, schema changes, Bulk/Tooling/Metadata API, or declarative automation.

MUST activate when the project contains a uiBundles/*/src/ directory and the task involves creating or configuring a Custom Application for hosting a UI bundle in Lightning Experience. Use this skill when creating a CustomApplication metadata record to surface the UI bundle in the App Launcher. Activate when files matching applications/*.app-meta.xml exist and need modification, or when the user wants to expose their app via the Lightning App Launcher without a Digital Experience Site. Do NOT use platform-custom-application-generate for this — UI bundle apps do not use tabs, action overrides, or flexipages.

MUST activate when the project contains a uiBundles/*/src/ directory and the user wants to add a pre-built feature — such as authentication (login, logout, protected routes, session management) or search (global search across pages and content) — instead of building it from scratch. Always run list first to see the current feature catalog, since it can include more than authentication and search. Always use this skill for installing pre-built features rather than hand-building them. DO NOT TRIGGER for Agentforce conversational client or file-upload features — use experience-ui-bundle-agentforce-client-generate and experience-ui-bundle-file-upload-generate respectively.

MUST activate when the project contains a uiBundles/*/src/ directory and the task involves creating or configuring site infrastructure. Use this skill when creating or configuring a Salesforce Digital Experience Site for hosting a UI bundle. Activate when files matching digitalExperiences/, networks/, customSite/, or DigitalExperienceBundle exist and need modification, or when the user wants to publish, host, or configure guest access for their app.

MUST activate when the project contains a uiBundles/*/src/ directory and the task involves uploading, attaching, or dropping files. Use this skill when adding file upload functionality to a UI bundle app. Provides progress tracking and Salesforce ContentVersion integration. This feature provides programmatic APIs ONLY — build custom UI using the upload() API. ALWAYS use this instead of building file upload from scratch with FormData or XHR.

Build SwiftUI layouts using stacks, grids, lists, scroll views, forms, and controls. Covers VStack/HStack/ZStack, LazyVGrid/LazyHGrid, List with sections and swipe actions, ScrollView with ScrollPosition and scroll-driven reveal surfaces, Form with validation, Toggle/Picker/Slider, .searchable, and overlay patterns. Use when building data-driven layouts, collection views, paged detail reveals, settings screens, search interfaces, or transient overlay UI.
