React/TypeScript UI component conventions, atomic hierarchy, classNames utility, variant/size dictionaries, polymorphic `as` prop, icon usage, composition slots, and Tailwind styling. Use when authoring or reviewing any `*.tsx` component.
Implements drag-and-drop and sortable interfaces with React/TypeScript including kanban boards, sortable lists, file uploads, and reorderable grids. Use when building interactive UIs requiring direct manipulation, spatial organization, or touch-friendly reordering.
Integrate the Transfer element (registry name `transfer`) for bridge-to-recipient flows in React/TypeScript apps. Use when installing or debugging cross-chain recipient transfers, allowance/intent approvals, source-selection constraints, and `sdk.bridgeAndTransfer` step execution.
Best practices and domain knowledge for building videos programmatically with Remotion (videos in React/TypeScript, rendered to MP4). Use whenever writing or editing Remotion code — scaffolding a video project, animating with interpolate/spring over useCurrentFrame(), sequencing scenes and transitions, captions/subtitles, audio, GIFs/Lottie/3D, charts, visual effects, dynamic duration via calculateMetadata, or rendering. Consult before reaching for a Remotion API, since its components and props evolve (e.g. @remotion/media).
MUST activate before editing ANY file under uiBundles/*/src/ for visual or UI changes to an EXISTING app — pages, components, sections, layout, styling, colors, fonts, navigation, animations, or any look-and-feel change. Use this skill when modifying pages, components, layout, styling, or navigation in an existing UI bundle app. Activate when the project contains appLayout.tsx, routes.tsx, src/pages/, src/components/, or global.css. This skill contains critical project-specific conventions (appLayout.tsx shell, shadcn/ui components, Tailwind CSS, Salesforce base-path routing, module restrictions) that override general knowledge. Without this skill, generated code will use wrong imports, break routing, or ignore project structure. Do NOT use when creating a new app from scratch (use building-ui-bundle-app instead).

Scaffold a new Metabase data-app into the connected remote-sync repository's `data_apps/<app>/` directory from the `data-app-template`. Use when the user asks to start, create, scaffold, or set up a data-app from scratch.
INVOKE THIS SKILL when building, iterating on, copying, or sharing a LangSmith Custom App — a React/TypeScript UI that runs inside LangSmith and reads the LangSmith API. Covers the langsmith apps CLI, pulling an existing app's source, replicating an app into another workspace, verifying app logic without a browser, and sanitizing an app before sending it outside your org. Uses the langsmith CLI tool.
Audit TypeScript and React code against expert-level best practices from 9 TypeScript library references. Use when the user wants to review, audit, check, or improve TypeScript code quality — including requests like "audit this file", "review my types", "check my TypeScript", "what's wrong with this code", "improve my TS", "type review", or any request to evaluate TypeScript code against modern patterns. Also use when the user mentions type safety, generics review, or React TypeScript patterns. Covers type safety, generics, narrowing, branded types, discriminated unions, React TypeScript patterns, type transformations, testing patterns, and mocking techniques.
