Claude Code skills for product, design, and development

This repo packages 47 Claude Code skills into one library of reusable workflows. The skills cover design review, product writing, Next.js setup, Supabase setup, Vercel deploys, code review, testing, and browser automation. The skills are grouped by workflow and stored under `.claude/skills/`, so you can copy all of them or only the categories you want. The README also points to `SKILL-GUIDE.md` for the shared skill format.

Who it's for

Builders who want Claude Code skills they can copy into their projects and reuse across product, design, and shipping work.

What it delivers

You can give Claude Code repeatable workflows for design, product, development, testing, and deployment instead of re-teaching the same process each time.

What it does

Design skills

Includes design frameworks like `frontend-design` and `design-foundations`, plus commands such as `/audit`, `/critique`, `/polish`, `/clarify`, and `/onboard`.

Product skills

Includes `jtbd` and `lean-canvas`, with commands for interviews, competitive analysis, PRDs, stories, prioritization, scope, GTM, metrics, and retros.

Development skills

Includes `vercel-react-best-practices`, `web-design-guidelines`, `typescript-patterns`, and `api-design`, plus setup, review, test, and deploy commands.

Browser automation tool

Includes `agent-browser` for navigating pages, filling forms, taking screenshots, scraping, and testing in the browser.

How to get it

  1. 1Install everything — copy all skills into any project
    cp -r .claude/skills/ your-project/.claude/skills/
  2. 2Install globally — available in every project
    cp -r .claude/skills/* ~/.claude/skills/

README

builder-skills

47 Claude Code skills for product management, frontend design, full-stack development, and browser automation. Organized by workflow — from discovery through deployment.

Setup

Install everything — copy all skills into any project:

cp -r .claude/skills/ your-project/.claude/skills/

Install globally — available in every project:

cp -r .claude/skills/* ~/.claude/skills/

Install selectively — pick only the categories you need (recommended if you have many skills already, to avoid context bloat):

# Just design skills
cp -r .claude/skills/design/ your-project/.claude/skills/design/

# Just product skills
cp -r .claude/skills/product/ your-project/.claude/skills/product/

# Mix and match
cp -r .claude/skills/dev/setup/ your-project/.claude/skills/dev/setup/
cp -r .claude/skills/dev/review/ your-project/.claude/skills/dev/review/

Skills

Design

Frameworks

Knowledge skills that provide design principles and decision-making context.

SkillReferencesCovers
frontend-design7Typography, color, spacing, motion, interaction, responsive, writing

Review/auditTechnical quality checks: a11y, performance, theming, responsive
/critiqueDesign review: hierarchy, clarity, emotional resonance
Refine/normalizeAlign with design system standards
/polishFinal pass before shipping
/distillStrip to essence, remove complexity
/clarifyImprove unclear copy and labels
/extractPull reusable components into design system
Adjust/bolderAmplify safe or boring designs
/quieterTone down overly bold designs
/colorizeAdd strategic color
/animateAdd purposeful motion
/delightAdd moments of joy and personality
Hardening/optimizePerformance: loading, rendering, bundle size
/hardenError handling, i18n, edge cases
/adaptAdapt for different devices and contexts
/onboardDesign onboarding flows and empty states

Product

Frameworks

Knowledge skills that provide product strategy and decision-making context.

SkillReferencesCovers
jtbd5Jobs to Be Done — core concepts, discovering/defining/designing/delivering value
lean-canvasOne-page business model — problem, solution, channels, metrics, unfair advantage

Commands

Slash commands for product management work. Most accept an optional argument to scope the work (e.g. /prd search-feature, /prioritize backlog).

GroupCommandWhat it does
Discover/interviewGenerate interview scripts or analyze transcripts for insights
/competitiveCompetitive analysis with feature comparison and positioning gaps
Define/prdWrite a product requirements document
/storiesWrite job stories with acceptance criteria
/specWrite a technical specification from requirements
Prioritize/prioritizeScore and rank features using RICE, opportunity scoring, or impact/effort
/scopeCut scope to identify MVP and must-haves for a timeline
Launch/gtmGo-to-market plan with positioning, messaging, and launch checklist
/metricsDefine success metrics, KPIs, and instrumentation plan
/retroRun a structured retrospective with actionable outcomes

Development

Commands

Slash commands for development workflows. Most accept an optional argument to scope the work.

GroupCommandWhat it does
Setup/nextjs-initScaffold Next.js with App Router, TypeScript, Tailwind, opinionated defaults
/supabase-setupInitialize Supabase: schema, RLS policies, auth, storage, edge functions
/vercel-deployDeploy to Vercel: config, env vars, domains, preview deploys
/db-schemaDesign a database schema from requirements (Postgres-first, Supabase-aware)
/env-configSet up environment variables across local/staging/production with validation
