What it does

Discover Frontend is an agent skill from rand/cc-polymath. Automatically discover frontend development skills when working with React, Next.js, UI components, state management, data fetching, forms, accessibility, performance optimization, or SEO. Activates for frontend web development tasks.

Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Claude Code. Compatible with any agent supporting the Agent Skills format.

It sits in Frontend & Design, covering State management, Accessibility and Frontend development. It works with Next.js and React. The repository describes itself as: Claude Code skills and workflows, optimized for context-efficiency and skill quality. Skills ranging from cloud infrastructure to design to advanced maths. The licence is MIT.

When your agent uses it

  • Tasks that involve State management
  • Tasks that involve Accessibility
  • Tasks that involve Frontend development

Example prompts

  • “/discover-frontend”

Requirements

  • Compatibility (from SKILL.md): Designed for Claude Code. Compatible with any agent supporting the Agent Skills format.

Workflow steps

11 steps, taken from the first numbered list in SKILL.md.

  1. react-component-patterns - Component design, composition, hooks, performance
  2. nextjs-app-router - Next.js 14+ App Router, Server Components, routing
  3. react-state-management - Context, Zustand, Redux Toolkit patterns
  4. react-data-fetching - SWR, React Query, Server Actions, data patterns
  5. react-form-handling - React Hook Form, Zod validation, form patterns
  6. web-accessibility - WCAG 2.1 AA compliance, ARIA, keyboard navigation
  7. frontend-performance - Bundle optimization, Core Web Vitals, code splitting
  8. nextjs-seo - SEO with Next.js, metadata API, structured data
  9. web-workers - Web Workers API, message passing, offloading computation
  10. browser-concurrency - Service Workers, SharedWorkers, Worklets, PWAs
  11. elegant-design/SKILL.md - World-class accessible interfaces (separate Agent Skill)

What it can do on your machine

Read from SKILL.md and the folder at commit baa2df1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code. Compatible with any agent supporting the Agent Skills format.

    From compatibility in the SKILL.md frontmatter.

Context cost

Discover Frontend loads about 2.4k tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 981 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~2.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Quick Start Examples

"Build a Next.js app with App Router": Read ../frontend/nextjs-app-router.md

"Create reusable React components": Read ../frontend/react-component-patterns.md

"Implement global state management": Read ../frontend/react-state-management.md

"Build a form with validation": Read ../frontend/react-form-handling.md

"Optimize my app performance": Read ../frontend/frontend-performance.md

"Make my app accessible": Read ../frontend/web-accessibility.md

"Improve SEO": Read ../frontend/nextjs-seo.md

"Offload heavy computation": Read ../frontend/web-workers.md

"Build a PWA with offline support": Read ../frontend/browser-concurrency.md

React vs Next.js Decision

Use React (Vite) when:

  • Building SPAs or client-heavy apps
  • Don't need SSR or SSG
  • Want full control over routing
  • Building component libraries

Use Next.js when:

  • Need SEO (Server-Side Rendering)
  • Want file-based routing
  • Need API routes
  • Building full-stack apps
  • Want optimal performance out of the box

State Management Decision

Use Component State (useState) when:

  • State is local to a component
  • Simple state that doesn't need sharing

Use Context when:

  • Sharing state across a few components
  • Theme, auth, or user preferences
  • Not frequently updated

Use Zustand when:

  • Need global state
  • Want simple API
  • State updates are moderate

Use Redux Toolkit when:

  • Complex state logic
  • Need middleware (sagas, thunks)
  • Large team with established patterns
  • Time-travel debugging needed

For detailed guidance: Read ../frontend/react-state-management.md

Data Fetching Decision

Server Components (Next.js App Router):

  • Default choice for Next.js 14+
  • Fetch on server, zero client JS
  • Direct database access

Server Actions (Next.js):

  • For mutations and form handling
  • Progressive enhancement
  • Type-safe with TypeScript

SWR:

  • Client-side data fetching
  • Built-in caching
  • Optimistic updates
  • Focus on user experience

React Query:

  • Advanced caching strategies
  • Complex data dependencies
  • Offline support
  • DevTools for debugging

For detailed patterns: Read ../frontend/react-data-fetching.md
