Planning & orchestration
These repos help Claude Code plan before it edits files, break work into stages and coordinate larger development workflows.
1. Superpowers — Adds structured brainstorming, planning, debugging and verification workflows so Claude thinks before it codes. Ideal for: reducing rewrites on complex builds. Repo: https://github.com/obra/superpowers
2. Everything Claude Code — A large reference setup combining agents, skills, hooks, rules, commands, MCPs, memory and verification patterns. Ideal for: building a more advanced Claude Code setup. Repo: https://github.com/affaan-m/everything-claude-code
3. gstack — Garry Tan’s workflow that splits product development into specialist roles across product, engineering, design, review and QA. Ideal for: founders and small teams building products with Claude Code. Repo: https://github.com/garrytan/gstack
Skills, agents & UI
These repos give Claude reusable expertise for specific jobs instead of relying on one generic prompt for everything.
4. Anthropic Skills — Anthropic’s official examples for packaging repeatable instructions, scripts and resources into reusable Claude skills. Ideal for: creating company-specific or project-specific workflows. Repo: https://github.com/anthropics/skills
5. wshobson/agents — A large library of specialist agents and workflows for research, architecture, implementation, testing and review. Ideal for: multi-agent development and larger tasks. Repo: https://github.com/wshobson/agents
6. UI/UX Pro Max — Adds detailed UI, UX, typography, accessibility and frontend guidance so Claude produces less generic interfaces. Ideal for: landing pages, dashboards and product UI. Repo: https://github.com/nextlevelbuilder/ui-ux-pro-max-skill
Memory & codebase understanding
These Claude Code tools help preserve context, understand large repositories and avoid rereading the same code every session.
7. Claude Mem — Adds persistent memory by saving and retrieving useful context from previous Claude Code sessions. Ideal for: projects you return to frequently. Repo: https://github.com/thedotmack/claude-mem
8. Planning With Files — Stores the task plan, findings and progress in files so long-running work survives context compaction. Ideal for: multi-step builds and research-heavy tasks. Repo: https://github.com/OthmanAdi/planning-with-files
9. Repomix — Packages a repository into an AI-friendly format with filtering, compression and token counting. Ideal for: giving Claude fast context on unfamiliar or large codebases. Repo: https://github.com/yamadashy/repomix
10. CodeGraph — Builds a structural graph of functions, classes, imports and call chains that Claude can query through MCP. Ideal for: navigating complex or older codebases. Repo: https://github.com/codegraph-ai/CodeGraph
Browser, web & engineering tools
These repos let Claude Code move beyond local files to test products, work with GitHub, browse live web data and connect to external systems.
11. Playwright MCP — Gives Claude browser automation so it can open your app, click through flows, test UI and verify its own changes. Ideal for: frontend testing and end-to-end QA. Repo: https://github.com/microsoft/playwright-mcp
12. GitHub MCP Server — GitHub’s official MCP server gives Claude access to repositories, issues, pull requests, Actions and other GitHub workflows. Ideal for: repo management, code review and CI debugging. Repo: https://github.com/github/github-mcp-server
13. Firecrawl — Lets Claude search, crawl and extract live websites into structured data or Markdown. Ideal for: current documentation, web research and external product data. Repo: https://github.com/firecrawl/firecrawl
14. Awesome MCP Servers — A community directory of MCP servers for databases, cloud tools, browsers, search, developer tools and more. Ideal for: finding new systems to connect to Claude Code. Repo: https://github.com/punkpeye/awesome-mcp-servers
Model routing & cost control
This category gives you more control over which model handles each Claude Code task and what you spend on it.
15. Claude Code Router - Routes Claude Code requests across different models and providers based on the type of task. Ideal for: reducing model costs and using stronger models only where they matter. Repo: https://github.com/musistudio/claude-code-router
