Design & UI
Create and validate OmniStudio FlexCards with 130-point scoring. Use when building at-a-glance UI cards, configuring data source bindings to Integration Procedures, or reviewing existing FlexCard definitions for accessibility and performance. TRIGGER when: the user creates FlexCards, configures data sources, designs card layouts, or asks about OmniUiCard metadata. DO NOT TRIGGER when: building OmniScripts (use sf-industry-commoncore-omniscript), creating Integration Procedures (use sf-industry-commoncore-integration-procedure), or analyzing dependencies (use sf-industry-commoncore-omnistudio-analyze).
Creative coding skills for Claude Code, claude.ai and Cowork. Motion, micro-interactions and design systems across Web (GSAP, Motion, Three.js, CSS), Android (Jetpack Compose) and Apple (SwiftUI). Proposes an interaction thesis you approve before it writes any code. Anti-AI-slop.
Build assistant-ui chat experiences for Expo and bare React Native with `@assistant-ui/react-native` and `@assistant-ui/ai-sdk`. Use when setting up an absolute mobile chat endpoint, `AssistantRuntimeProvider`, `useChatRuntime`, `AssistantChatTransport`, native `ThreadPrimitive`, `ComposerPrimitive`, `MessagePrimitive`, thread lists, attachments, React Native styles, `Metro` `withAui` for a `"use generative"` toolkit, local or remote thread adapters, or migrating a web chat surface to iOS and Android. Route here when a relative API URL fails on device, a native primitive lacks runtime state, `Metro` does not compile a toolkit, or web Elements are being used in a native app. Route web setup and DOM primitive work to `../setup/SKILL.md` and `../primitives/SKILL.md`.
Accessibility audit skill for scanning, fixing, and verifying WCAG 2.2 Level A and AA compliance across React, Next.js, Vue, Angular, Svelte, and plain HTML codebases. Use when auditing accessibility, fixing a11y violations, checking color contrast, generating compliance reports, or integrating accessibility checks into CI/CD pipelines.
Regression check — diff a live page's web accessibility (a11y) violations against a baseline. By default it compares your uncommitted changes (stash-based); pass `--branch [<name>]` to compare against a branch. Reports the new WCAG violations introduced, the ones fixed, and the count of pre-existing ones. Use it for 'did my change break accessibility', 'what a11y issues did this PR add', or as a CI gate. For a full scan of one page use `accessibility-scan`; for a whole site use `accessibility-audit`.

Tailwind CSS patterns and conventions. Use when writing responsive designs, implementing dark mode, creating reusable component styles, configuring Tailwind, or migrating from v3 to v4. Triggers on tasks involving Tailwind classes, responsive design, dark mode, CSS styling, or "migrate to Tailwind v4".
UX research and design toolkit for Senior UX Designers/Researchers, including data-driven persona generation, journey mapping, usability testing frameworks, and research synthesis. Use when conducting user research, creating personas, mapping user journeys, planning usability tests, or validating designs.
This skill is for enhancing the visual design and aesthetics of Next.js web applications. It provides modern UI components, design patterns, color palettes, animations, and layout templates. Use it to improve styling, create responsive designs, implement modern UI patterns, add animations, select color schemes, or build attractive frontend interfaces
Apply a Swiss International Style design system using Tailwind CSS. Use when asked to style a webpage, clean up a UI, apply a design system, make something look great, or when the user references Swiss design, grotesque fonts, Helvetica, grid systems, modernist typography, or 1960s/1950s design aesthetics. Implements IBM Plex Sans typography, stone color palette, opacity-based hierarchy, generous whitespace, and structured grid layouts.
Use when the user asks for persona builder or a task matching the examples below. Whip a person into a more marketable shape online. Read their socials and the way they talk, then deliver real talk about where the money is, what's holding them back, and what to fix — then ship the designed multi-page Influencer Persona PDF + a persona.md folder kit that downstream skills (ugc-ads, podcast, founder-product-video, app-sizzle, app-store-screens) can consume. Input is the person themselves: socials, camera roll, taste URLs, a selfie video, or start-from-scratch answers. Visual/PDF stages still require real curated imagery: user-provided photos, or clean public-feed frames from a supported social handle. Output is a self-contained kit + a roadmap to actually become that persona online. Trigger phrases: "build my influencer identity", "make me a creator brand", "personal brand for [niche]", "build my online persona", "influencer persona.md", "I want to be an influencer", "make my creator identity", "persona.md for my socials", "creator identity for @[handle]", "persona-builder", "glow up my online presence".
Sets up and uses Tailwind CSS v4 in Capacitor apps - CSS-first config (`@import "tailwindcss"`, `@theme`, `@utility`, `@custom-variant`, `@source`, `@plugin`), `@tailwindcss/vite` / `@tailwindcss/postcss`, upgrading from v3 `tailwind.config.js` with `npx @tailwindcss/upgrade`, WebView browser floor (Safari 16.4+ / Chrome 111+ vs Capacitor iOS 15/16 targets), safe-area utilities built on `env(safe-area-inset-*)`, platform variants (`ios:`/`android:` via a root class), class-based dark mode, `pointer-coarse:` touch targets, and hover-on-touch behavior. Use when installing Tailwind in a Capacitor project, styles do not apply after upgrading to v4, colors look wrong on older iPhones, or building mobile layouts with Tailwind. Do not use for Konsta UI components (konsta-ui), Ionic theming (ionic-design), native system bar / edge-to-edge config (safe-area-handling), or keyboard overlap (capacitor-keyboard).
One page, hands-on manual tier — drive a live page through the web accessibility (a11y) checks a rule engine can't decide: keyboard operation and focus order, screen-reader names, roles and states from the accessibility tree, reflow and zoom, reduced motion, form errors, and target size. Grades each finding by evidence basis (verified / confirm-with-a-human / human-required) and severity, and closes every criterion in a ledger: verified, flagged, not exercised, or N/A. Locates and assesses; does not fix (use `accessibility-fix`). Use it for keyboard testing, focus-order checks, screen-reader or a11y-tree review, reflow and zoom at 200%, or 'is this operable, not just lint-clean'. The automated tier is `accessibility-scan`; `accessibility-audit` runs both across a sampled site.
Configures and uses snipgrapher to generate polished code snippet images, including syntax-highlighted PNGs, SVGs, and WebP exports with custom themes, profiles, and styling options. Use when the user wants to create code screenshots, turn code into shareable images, generate pretty code snippets for docs or social posts, produce syntax-highlighted images from source files, or explicitly mentions snipgrapher. Supports single-file renders, batch jobs, watch mode, and reusable named profiles via the snipgrapher CLI or npx.

Use it for bespoke visualizations beyond standard charting libraries, whether in React, Vue, Svelte, vanilla JavaScript, or any other environment.
Always use when running Sa11y accessibility Jest tests for an LWC — locally before pushing, producing the command(s), running one file vs a suite, selecting tests by naming convention, saving Sa11y-rendered HTML, or reproducing a Sa11y/A11yBug failure. Covers core (Bazel: `bazel test //<module>:<target>`) and standalone `npx jest` (`.accessibility.test.js`, `@sa11y/jest`). Required for a `run-plan.md`, a failing a11y test's exit code, or `SA11Y_*`/`A11yBug`/core-Bazel test paths.

Generate genuinely beautiful, on-brand UI instead of generic "AI slop" — use whenever the user asks to build, design, style, or improve a UI, landing page, dashboard, app screen, or component, whenever a PRD/spec needs a design pass before implementation, whenever the user pastes reference images/Pinterest/Dribbble links and wants the app to look like them, or whenever the user complains the AI-generated UI looks generic, boring, cookie-cutter, or "like every other AI app." Make sure to trigger this even if the user doesn't say "design" explicitly — phrases like "make this look good", "build the frontend for X", "this looks like every other SaaS site", or "match this vibe" all qualify. Also triggers on two verbs, "study"/"extract the look of" a reference screenshot or URL, and "audit"/"review"/"why does this look AI-generated" for critiquing existing UI.
