Everything on the browser side of a LangWatch module: createUi and the shell, a module's browser-half layer order (model/behavior/ui), host services vs components (browser-host vs design-system), where shared code goes now that kits are gone (record §3.4), building a new browser module end to end (defineBrowserModule, screens, drawers, lends, the module's *HostApi, the derived tRPC client), drawers as routed singletons, and frontend testing (colocated __tests__, jsdom docblock, component tests as integration level). Use whenever someone is building a screen, drawer, or shell chrome; writing or extending a module's browser/ package; asking how a screen reads host services (tokens, its own `*HostApi`); sharing a component, hook or data with another module (design system, contract, `<name>-client`); or writing/reviewing a component test.

Implement and review the Cursor BYOK React/Tauri desktop frontend. Use for changes under apps/desktop involving routing, page layout, window chrome, settings UI, scrolling, virtualization, charts, themes, or frontend component architecture.

Build and change LLM Gateway Next.js frontends — apps/ui, apps/playground, apps/code, apps/airside, and ee/admin — including API calls, data fetching, navigation, dashboard routes, dialogs and popovers, charts, number formatting, and user settings. Use when editing React components or pages in those apps, adding a dashboard page, calling the API from the UI, or formatting displayed values.

Use when building or changing anything in the frontend: a page, a component, a layout, styling, copy on screen. Produces distinctive, production-grade UI that fits this project's existing design, covers every state, is accessible, and is checked in a browser before it is called done.

Use when building, designing, redesigning, or reviewing any UI in the dashboard React frontend (client/dashboard, including the inlined Speakeasy Elements code) — a new page, tab, card, table, form, dialog, sheet, empty or error state, settings section, or UI copy — and when addressing design feedback or Gutternote comments on a preview. Triggers: "build a page for", "add UI for", "make this look better", "redesign", "the UX is confusing", "layout shift", "overflow", "add a tab", "dashboard component".

Use when making architecture-level React decisions — component decomposition, choosing where state should live, selecting a state manager (Context vs Redux vs Zustand) or a data-fetching library (TanStack Query vs SWR), or planning a rendering-performance budget. For advanced hook patterns, use react.

Internal PostHog developer frontend/browser QA skill. Use only when a PostHog developer explicitly asks to run frontend QA, browser-test a PR, verify a UI flow against the local PostHog stack, use qa-frontend, or QA current frontend changes with browser/runtime evidence, or to make a feature reel (see reel mode below). Do not use for generic code review, PR review, "check my changes", CI debugging, or security audit; use qa-team, debugging-ci-failures, or security-audit instead. QA runs in PR mode or local mode, plans adaptive browser and visual checks, drives browser MCP/tooling such as Playwright MCP or Chrome DevTools MCP, captures evidence, and applies only approved/narrow fixes. Reel mode makes a feature reel instead: a short, sharp animated WebP of one UI flow for a PR description. Use it when asked for a reel, GIF, or animated demo, or when writing-pr-descriptions calls for a reel: a new action and its effect that one screenshot cannot show.

Frontend engineering for browser-facing applications: component and browser contracts, semantic accessibility, UI systems, responsive behavior, security, resilient user states, and feature ownership. Use when building or auditing frontend contracts, styling infrastructure, browser integrations, or file organization. Use typescript for language-wide modeling, narrowing, generics, assertions, and runtime type evidence; use react for React composition, state, effects, Suspense, and rendering; use nextjs-app-architecture for Next.js-specific mechanics.
Generic frontend development patterns for VeChain dApps — React Query, Turborepo architecture, state management, Chakra UI, i18n, loading states, and transaction UX.

Context-led frontend design: art direction derived from product, audience, brand and the existing system, not generic defaults. Named mood variants listed inside. Triggers: frontend, UI, CSS, styling, visual, theme, component, layout, responsive, accessibility, animation.

React, components, state management, and modern frontend concepts. Activated when Claude works with .jsx/.tsx files or React-related code. Most vibecoded apps use React.

Build interfaces by describing what you want, not how to code it. Say "I need a dashboard with three stat cards" — get a working UI for screens, VR headsets, and holograms from one description. See something wrong? Click it, leave a note, it gets fixed. No coding required. No framework knowledge needed.

A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
How do I use one I find here?
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
What do the warnings mean?
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Which skills worked for people?
Open a skill to see its discussion. Reports from people and their agents are coming.
