frontend-design
julianoczkowski/designer-skills
Build distinctive, production-grade frontend interfaces with high design quality, guided by named aesthetic philosophies. Use when building components, pages, or applications. Generates working code with exceptional attention to aesthetic details and creative choices that avoid generic AI output.
setup
assistant-ui/skills
Installs and configures assistant-ui in a project via the CLI, and picks the right runtime for a backend. Use for first-time install, scaffold, or config: `npx assistant-ui@latest create my-app` (templates default, minimal, cloud, cloud-clerk, langchain, mcp, eve), `npx assistant-ui@latest init [--yes] [--overwrite]` in an existing Next.js app, or `npx assistant-ui@latest add` registry components (thread, markdown-text, thread-list, tool-fallback). Also covers the other CLI verbs: doctor, info, update, upgrade, mcp, and agent. Use to choose a runtime hook for a backend: useChatRuntime (AI SDK v7), useLangGraphRuntime, useAgUiRuntime, useA2ARuntime, useLocalRuntime (custom streaming API), or useExternalStoreRuntime (Redux/Zustand). Covers Vite/TanStack Start setup, Expo (--native) and React Ink (--ink) scaffolds, shadcn and Base UI registry styles, the playground --preset flag, and avoiding the deprecated @assistant-ui/styles and @assistant-ui/react-ui packages. For upgrading an existing install or post-upgrade breakage use update; for building UI from raw parts use primitives.
motion-advanced
affaan-m/ecc
Advanced motion patterns for React / Next.js — drag & drop, gestures, text animations, SVG path drawing, custom hooks, imperative sequences (useAnimate), loaders, and the full API decision tree. Requires motion-foundations. Use when building drag and drop, gestures, text or SVG animation, or imperative animation sequences in React or Next.js.
ui-to-vue
affaan-m/ecc
Use when the user has UI screenshots or design exports that need batch conversion into Vue 3 components, especially with Vant, Element Plus, or Ant Design Vue.
motion-patterns
affaan-m/ecc

Use when animating a specific UI element in React or Next.js — button, modal, toast, stagger, page transition, or scroll.
platform-custom-application-generate
forcedotcom/sf-skills
Use this skill when users need to create or configure tab-based Salesforce Custom Applications with navigation, branding, and action overrides. Trigger when users mention custom apps, application metadata, app navigation, or organizing tabs into applications. Use when users want to create app containers for tabs and pages. Do NOT use when the goal is hosting a React UI bundle in the App Launcher — use experience-ui-bundle-custom-app-generate for that case.
update
assistant-ui/skills
Upgrades an existing assistant-ui project to current releases and executes the resulting migrations. Use when the user wants to update, upgrade, bump, or migrate @assistant-ui/react, @assistant-ui/react-ai-sdk, ai, or @ai-sdk/react, hits peer-dependency conflicts or post-upgrade type errors, or must apply renamed APIs after a version jump. Detects installed versus latest versions via npm ls / npm view, then routes through breaking-change references for each jump (AI SDK v4/v5 to v6 to v7; assistant-ui 0.8.x to 0.15.x): aui.thread() accessor calls to aui.thread properties, removal of the legacy context hooks useAssistantRuntime/useThreadRuntime/useThread/useMessage/useComposer in favor of useAui and useAuiState, s.tools.tools to s.tools.toolUIs, the groupPartByType mcp-app key to standalone-tool-call, useAssistantApi to useAui, runtime.threadList to runtime.threads, ThreadPrimitive.ViewportSlack removal, the primitives components prop to children render functions, toDataStreamResponse to toUIMessageStreamResponse, maxSteps to stopWhen: stepCountIs(n). Runs npx assistant-ui@latest upgrade, npx assistant-ui@latest update, npx assistant-ui@latest doctor, and npx tsc --noEmit to verify. For a first-time install or fresh scaffold (not an upgrade) use setup instead.
react-expert
jeffallan/claude-skills

experience-ui-bundle-frontend-generate
forcedotcom/sf-skills
MUST activate before editing ANY file under uiBundles/*/src/ (or the bundle's index.html) for visual or UI changes to an EXISTING app — pages, components, sections, layout, styling, colors, fonts, navigation, animations, branding, or any look-and-feel change. Use this skill when modifying pages, components, layout, styling, navigation, or branding in an existing UI bundle app. Activate when the project contains appLayout.tsx, routes.tsx, src/pages/, src/components/, src/styles/global.css, or the bundle's index.html. 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 or the bundle has not been scaffolded yet (use experience-ui-bundle-app-coordinate instead).

MUST also activate when the task spans more than one ui-bundle skill. Use this skill when building a complete app end-to-end. Do NOT use for Lightning Experience apps with custom objects (use platform-lightning-app-coordinate). Do NOT use for single-concern edits to an existing page (use experience-ui-bundle-frontend-generate).
experience-ui-bundle-agentforce-client-generate
forcedotcom/sf-skills
Use this skill when the user asks to add, embed, integrate, configure, style, or remove an agent, chatbot, chat widget, conversation client, or AI assistant in a UI Bundle project (React or Angular). TRIGGER when: project contains a uiBundles/*/src/ directory and the task involves adding or modifying a chat widget, chatbot, or conversational AI; files under uiBundles/*/src/ import AgentforceConversationClient in React `.tsx`/`.jsx` files, or use the app-agentforce-conversation-client element in Angular `.html` templates and AgentforceConversationClientComponent in `.component.ts` files; user asks to add any chat or agent functionality to a page.
