Frontend web orchestrator

Frontend Web Orchestrator

The single entry skill for browser-UI work. It locates the task on the framework × concern map and delegates to one of 18 specialist spokes. The cross-cutting model every web UI shares — the rendering/runtime choice that cascades into hydration, data fetching, motion bindings, and accessibility — lives in frontend-web-core; read it before picking a framework or wiring SSR-sensitive code.

Cluster map (spoke → role)

Framework core

• react-patterns — React 18/19 hooks discipline, server/client boundaries, Suspense, form actions, composition
• react-performance — the Vercel-derived 70-rule performance ruleset (waterfalls → re-render → micro-perf)
• react-testing — React Testing Library + Vitest/Jest + MSW + axe; the component-vs-e2e boundary
• nextjs-turbopack — Next.js 16+ with Turbopack: incremental bundling, FS caching, Turbopack-vs-webpack
• nuxt4-patterns — Nuxt 4 hydration safety, route rules, lazy loading, SSR-safe useFetch/useAsyncData
• angular-developer — Angular signals/resource, forms, DI, routing, SSR, plus a 34-file reference set
• ui-to-vue — batch-convert UI screenshots/exports into Vue 3 (Vant, Element Plus, Ant Design Vue)

Build & runtime

• vite-patterns — Vite config, plugins, HMR, env, proxy, SSR, library mode, dependency pre-bundling
• bun-runtime — Bun as runtime / package manager / bundler / test runner; when to pick Bun over Node

Motion (layered — foundations first)

• motion-foundations — motion tokens, spring presets, perf rules, device adaptation, reduced-motion, SSR safety. Every other motion skill depends on this.
• motion-patterns — production UI patterns (button, modal, toast, stagger, page transitions, scroll) built on the foundation
• motion-advanced — drag/gestures, text animation, SVG path drawing, useAnimate sequences, the full API decision tree

Look & feel

• accessibility — WCAG 2.2 AA: POUR, semantic ARIA, target size, focus appearance, Web + iOS/Android. The spec/audit authority.
• frontend-a11y — the React/Next implementation of a11y: labels, ARIA, keyboard nav, focus management
• design-system — generate or audit design systems, token/visual consistency, review styling PRs
• make-interfaces-feel-better — concrete design-engineering polish: spacing, type, borders, shadows, hit areas, states
• frontend-design-direction — set a product-appropriate visual direction before implementation
• frontend-slides — animation-rich HTML presentations from scratch or converted from PPTX

Routing rules by intent

• "Build / review a React component" → react-patterns (+ frontend-a11y for interactive elements, react-testing for coverage)
• "It's slow / re-rendering / big bundle" → react-performance; if Next.js dev speed → nextjs-turbopack
• "Vue / Nuxt" → nuxt4-patterns; converting designs to Vue components → ui-to-vue
• "Angular" → angular-developer (everything Angular routes here; it carries its own reference set)
• "Add an animation / transition" → motion-foundations FIRST, then motion-patterns; gestures/SVG/imperative → motion-advanced
• "Make it accessible" → accessibility for the WCAG standard (browser DOM/ARIA), frontend-a11y for the React implementation
• "Make it look better / more polished / on-brand" → make-interfaces-feel-better + frontend-design-direction + design-system
• "Bundler / dev server / monorepo tooling" → vite-patterns or nextjs-turbopack; runtime/package-manager → bun-runtime
• "Build a deck / slides" → frontend-slides

Standard flow

1. Pick the rendering model — which framework, and CSR / SSR / RSC? This is the decision in frontend-web-core that everything else inherits.
2. Route to the framework spoke for structure (react-patterns / nuxt4-patterns / angular-developer).
3. Layer cross-cutting concerns in order: accessibility (frontend-a11y + accessibility) → motion (motion-foundations → motion-patterns/motion-advanced) → polish (make-interfaces-feel-better, design-system).
4. Tooling & verification — wire the bundler/runtime (vite-patterns / nextjs-turbopack / bun-runtime); verify with react-testing.
5. Return: chosen spoke(s), the rendering model implied (SSR/RSC sensitivity), the a11y + reduced-motion obligations, and the next action.

Sibling clusters

This cluster is browser UI only (DOM, CSS, web frameworks). For native mobile UI, hand off — don't try to route React/Vue web idioms onto a device screen:

• React Native screens / components → react-native cluster
• Expo / managed React Native apps → expo cluster
• Flutter / Dart UI → mobile-flutter cluster

The accessibility spoke here is the WCAG spec/audit authority and states cross-platform principles, but implementation in this cluster is browser DOM/ARIA; native a11y belongs to the mobile clusters above.

Guardrails

See frontend-web-core. In short: respect the SSR boundary — wrap stateful/motion components in "use client" and match server/client initial state to avoid hydration mismatch; layer motion on motion-foundations (never inline ad-hoc durations); accessibility is not optional — semantic HTML first, every interactive element keyboard-reachable, every animation honors prefers-reduced-motion; never mix motion/react and framer-motion in one project. Pick the framework once and route consistently — don't blend React and Vue idioms in the same surface.

Picked-up spokes

Additional frontend-web spokes adopted from the antigravity-awesome-skills (MIT) library. These extend the cluster into auth, deployment, search, 3D, and component-library territory. Route to them the same way as the core spokes (load on demand, see below).

Auth & integration

• nextjs-supabase-auth — Supabase Auth on the Next.js App Router: browser/server clients, middleware session refresh, auth callback route
• clerk-auth — Clerk auth: App Router setup, middleware-protected routes, organizations, webhooks, user→DB sync
• shopify-apps — Shopify embedded apps (Remix/React Router + App Bridge), GraphQL Admin API, webhooks, Polaris, billing, extensions

Search

• algolia-search — Algolia indexing strategies, React InstantSearch hooks/widgets, faceting, relevance tuning

Deploy & ship (Vercel)

• deploy-to-vercel — deploy apps/sites to Vercel, preferring git-push preview deploys + proper linking ("deploy my app", "push this live")
• vercel-cli-with-tokens — Vercel CLI via token auth (VERCEL_TOKEN) for CI / non-interactive deploys and env-var management
• vercel-deployment — Next.js-on-Vercel knowledge: env vars per environment, edge/serverless functions, build config, production rollout
• vercel-optimize — observability-first Vercel cost/perf audit: production metrics → deterministic gates → version-aware recommendations

React quality & FP

• react-component-performance — diagnose a slow React component: isolate ticking state, stabilize props/handlers, memoize leaves, virtualize, verify in Profiler
• senior-frontend — senior React/Next/TS/Tailwind workflows: scaffolding, component/hook generation, bundle analysis, patterns, a11y, testing (ships scripts)
• fp-ts-errors — errors-as-values in TypeScript with fp-ts Either/TaskEither; validation-error accumulation instead of try/catch
• fp-ts-react — fp-ts in React: Option/Either/TaskEither/RemoteData for state, forms, and data fetching (React 18/19, Next 14/15)

Component libraries & view transitions

• shadcn — manage shadcn/ui: add from registries via CLI, compose, style with semantic tokens, enforced rule set (user-invocable: false — agent-loaded)
• rayden-code — generate React + Tailwind using the Rayden/Rayna UI library (34 components) with correct props/tokens and an anti-pattern ban list
• vercel-react-view-transitions — native React/Next view transitions: shared elements, route transitions, transition types, reduced-motion-safe

3D / WebGL

• 3d-web-experience — broad 3D-for-web architect: Three.js, React Three Fiber, Spline, WebGL, GLSL — configurators, immersive sites
• threejs-skills — focused Three.js best practices: scene setup, lighting, controls, animation loops, effects, data viz in 3D

Testing & extensions

• awt-e2e-testing — AI-driven E2E web testing via declarative YAML → Playwright with visual matching (OpenCV + OCR), no brittle selectors
• browser-extension-builder — cross-browser extensions (Chrome/Firefox): Manifest V3, content scripts, service workers, popup UIs, Web Store publishing

Routing the picked-up spokes by intent

• "Add login / auth" → nextjs-supabase-auth (Supabase) or clerk-auth (Clerk); Shopify merchant app → shopify-apps
• "Add search to the site/app" → algolia-search
• "Deploy / ship this" → deploy-to-vercel (interactive), vercel-cli-with-tokens (CI/token); Next.js specifics → vercel-deployment; "it's expensive / slow in prod" → vercel-optimize
• "Component is slow" → react-component-performance (pairs with the core react-performance ruleset)
• "Scaffold a React/Next app, generate components" → senior-frontend
• "Type-safe error handling / functional React" → fp-ts-errors, then fp-ts-react
• "Use shadcn / a design-system component lib" → shadcn; Rayden/Rayna stack → rayden-code
• "Animate between routes / shared element" → vercel-react-view-transitions (native view transitions; for spring/gesture motion stay on motion-*)
• "Build something in 3D / WebGL" → 3d-web-experience for the stack decision and React Three Fiber, threejs-skills for raw Three.js implementation
• "Write E2E browser tests with AI" → awt-e2e-testing (complements react-testing for component-level coverage)
• "Build a browser extension" → browser-extension-builder

Note: React Native and Makepad (Rust native UI) skills were intentionally not adopted here — native mobile UI hands off to the react-native / expo / mobile-flutter siblings below, and this cluster stays browser-only.

Loading spokes on demand

To keep CLI startup context lean, this cluster's spokes are not separately registered as skills — only this orchestrator and its *-core are enumerated. When you route to a spoke named above, load it on demand by reading its file:
