Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.
VercelSkillvercel/next.js/.agents/skills/react-sync/SKILL.md
Build local React changes in the bundle variants consumed by Next.js, sync them into a local Next.js checkout, and test the resulting integration. Use when working on React changes that need validation in Next.js, or when asked to run buildForNext, pnpm sync-react, or synchronize a React checkout with Next.js.
VercelSkillvercel/next.js/.agents/skills/react-vendoring/SKILL.md
React vendoring and react-server layer boundaries. Use when editing entry-base.ts, $$compiled.internal.d.ts, compiled/react* packages, or taskfile.js copy_vendor_react. Covers the entry-base.ts boundary (all react-server-dom-webpack/* imports must go through it), vendored React channels, type declarations, Turbopack remap to react-server-dom-turbopack, ComponentMod access patterns, and ESLint suppression for guarded requires.
VercelSkillvercel/next.js/.agents/skills/sandbox-bench/SKILL.md
Benchmark React or Next.js changes on Vercel Sandbox VMs with paired A/B statistics: react PR/commit vs base, or Next.js PR/commit vs base, measured end-to-end through the bench/render-pipeline app (rps, latency, p95; TTFB, RSS and document/Flight bytes when the Next side captures them) and, for React changes, through the react repo's flight-ssr-bench fixture (Node AND Edge web-streams paths, Fizz and Flight+Fizz). Use whenever the user asks to bench, perf test, or A/B a React PR, a react-server-dom / Flight / vendored React change, or a Next.js PR ("is this PR faster", "does this regress RSC?", "measure the perf impact of <commit>"), even if they don't say "benchmark" — any request to quantify a server-side performance difference between two revisions belongs here. Runs remotely (laptop-free), applies correctness gates before measuring, and reports boot-level confidence intervals.
SupabaseSkillsupabase/supabase/.agents/skills/react-hook-form/SKILL.md
Correct React Hook Form usage anywhere in the monorepo — data flow, subscriptions,
Significant-GravitasSkillSignificant-Gravitas/AutoGPT/.claude/skills/vercel-react-best-practices/SKILL.md
React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
affaan-mSkillaffaan-m/ECC/.agents/skills/frontend-patterns/SKILL.md
Frontend development patterns for React, Next.js, state management, performance optimization, and UI best practices. Use when building or reviewing React or Next.js components, state, or render performance.
SupabaseSkillsupabase/supabase/.agents/skills/studio-queries/SKILL.md

SupabaseSkillsupabase/supabase/.agents/skills/vercel-composition-patterns/SKILL.md
React composition patterns that scale. Use when refactoring components with
affaan-mSkillaffaan-m/ECC/.agents/skills/documentation-lookup/SKILL.md
Use up-to-date library and framework docs via Context7 MCP instead of training data. Activates for setup questions, API references, code examples, or when the user names a framework (e.g. React, Next.js, Prisma).
affaan-mSkillaffaan-m/ECC/.cursor/skills/documentation-lookup/SKILL.md
Use up-to-date library and framework docs via Context7 MCP instead of training data. Activates for setup questions, API references, code examples, or when the user names a framework (e.g. React, Next.js, Prisma).
langgeniusSkilllanggenius/dify/.agents/skills/e2e-cucumber-playwright/SKILL.md
Use when writing, changing, or reviewing Cucumber and Playwright tests under `e2e/`, including feature files, step definitions, support code, scenario tags, locators, and assertions. Do not use for Vitest, React Testing Library, backend tests, or generic browser automation outside the E2E suite.
langgeniusSkilllanggenius/dify/.agents/skills/frontend-testing/SKILL.md
Use when writing or changing Vitest or React Testing Library tests under `web/` or `packages/dify-ui/`, or when the user explicitly requests frontend test strategy, including evaluation of an existing strategy. Do not use for frontend code-review-only requests, general testability discussion, Python tests, or Cucumber/Playwright E2E.
AnthropicSkillanthropics/skills/skills/web-artifacts-builder/SKILL.md
Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.
MicrosoftSkillmicrosoft/vscode/extensions/copilot/assets/prompts/skills/project-setup-info-context7/SKILL.md
Comprehensive setup steps to help the user create complete project structures in a VS Code workspace. This tool is designed for full project initialization and scaffolding, not for creating individual files. When to use this tool: when the user wants to create a new complete project from scratch; when setting up entire project frameworks (TypeScript projects, React apps, Node.js servers, etc.); when initializing Model Context Protocol (MCP) servers with full structure; when creating VS Code extensions with proper scaffolding; when setting up Next.js, Vite, or other framework-based projects; when the user asks for \"new project\", \"create a workspace\", or \"set up a [framework] project\"; when you need to establish a complete development environment with dependencies, config files, and folder structure. When NOT to use this tool: when creating single files or small code snippets; when adding individual files to existing projects; when making modifications to existing codebases; when the user asks to \"create a file\" or \"add a component\"; for simple code examples or demonstrations; for debugging or fixing existing code. This tool provides complete project setup including folder structure creation, package.json and dependency management, configuration files (tsconfig, eslint, etc.), initial boilerplate code, development environment setup, and build and run instructions. Use other file creation tools for individual files within existing projects.

obraSkillobra/superpowers/skills/receiving-code-review/SKILL.md
Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation
obraSkillobra/superpowers/skills/writing-skills/SKILL.md
Use when creating new skills, editing existing skills, or verifying skills work before deployment

affaan-mSkillaffaan-m/ECC/.agents/skills/agent-sort/SKILL.md
Build an evidence-backed ECC install plan for a specific repo by sorting skills, commands, rules, hooks, and extras into DAILY vs LIBRARY buckets using parallel repo-aware review passes. Use when ECC should be trimmed to what a project actually needs instead of loading the full bundle.
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.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
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.
Open a skill to see its discussion. Reports from people and their agents are coming.
