Open Source
Tools That Actually Help
Curated open source projects for people who want to get more out of Claude. All battle-tested, all real GitHub repos — no fluff.
Superpowers for Claude Code
A complete software development methodology for coding agents. Provides 20+ battle-tested skills — TDD, debugging, brainstorming, planning — that make Claude Code reliably ship production-quality work without hand-holding.
Use cases
- Test-driven development that actually works
- Systematic multi-step debugging
- Task planning + autonomous execution
- Brainstorming before writing any code
Claude Code slash command
/plugin install superpowersRTK — Rust Token Killer
A single Rust binary that sits between Claude Code and your shell, filtering and compressing command output before it hits your context window. Zero config — a PreToolUse hook rewrites commands transparently.
Use cases
- 60–90% fewer tokens on git, cargo, tsc, pytest runs
- Dramatically lower API costs on long sessions
- Keeps context window clean for the actual problem
- Works with Claude Code, Cursor, Copilot, Windsurf
Install script (Bash)
curl -fsSL https://raw.githubusercontent.com/rtk-ai/rtk/master/install.sh | shMCP Servers (Model Context Protocol)
Official reference implementations for MCP — the open protocol that lets Claude securely access external tools and data. Includes ready-to-use servers for filesystem, Git, memory, web fetch, and more.
Use cases
- Give Claude persistent memory across sessions
- Let Claude read/write your local files safely
- Connect Claude to any database or REST API
- Build your own custom tool servers
Run memory server (npx)
npx -y @modelcontextprotocol/server-memoryClaude Code Action
Official Anthropic GitHub Action that wires Claude directly into your PR workflow. Mention @claude in any PR or issue comment to get code reviews, fix suggestions, or full implementations — all triggered from GitHub.
Use cases
- Automated code review on every PR
- Ask Claude to implement a fix directly in the PR
- Answer architecture questions from issue threads
- Works with Anthropic API, AWS Bedrock, or Google Vertex
GitHub Actions workflow
uses: anthropics/claude-code-action@v1Anthropic Cookbook
Official collection of Jupyter notebooks and copy-paste code recipes for the Claude API. Covers every major pattern from RAG and vision to prompt caching, tool use, structured outputs, and evaluations.
Use cases
- Learn the Claude API from working examples
- RAG with Pinecone, Chroma, or any vector store
- Multimodal: images, PDFs, documents
- Build evals and measure prompt quality
Clone & run locally
git clone https://github.com/anthropics/anthropic-cookbookSuperpowers Chrome
Claude Code plugin for direct Chrome browser control via the DevTools Protocol. No Selenium, no Playwright — Claude talks to your browser natively, making web automation and testing genuinely usable.
Use cases
- UI testing driven by Claude in plain English
- Scraping and data extraction workflows
- Automate repetitive browser tasks via prompts
- Works with the Superpowers skills framework
