10 GitHub repos that make Claude dramatically more useful
Discussion
Been going deep on the Claude ecosystem lately and found some genuinely useful repos worth bookmarking. Here's my list:
1. anthropics/claude-code-skills Anthropic's official skills library. SKILL.md files for handling docs, PDFs, spreadsheets, and more. The foundation everything else is built on.
2. yamadashy/repomix Packs your entire codebase into a single AI-readable file. Solves the "Claude only sees one file at a time" problem instantly. 20k stars and honestly essential.
3. Khalidabdi1/design-ai A library of DESIGN.md files scraped from real products like Stripe, Linear, and Vercel. Drop one into your Claude context and your AI stops generating generic UIs and actually builds with taste. Just crossed 100 stars.
4. hesreallyhim/awesome-claude-code The most curated list of Claude Code skills, hooks, slash-commands, and agent orchestrators. High signal, low noise.
5. travisvn/awesome-claude-skills Community-built skills for every use case imaginable: SEO, design, security, writing, testing. 22k installs.
6. ComposioHQ/awesome-claude-skills Another great skills collection. Standout ones: artifacts-builder for React/Tailwind artifacts, and a changelog generator that turns git commits into readable release notes.
7. rohitg00/awesome-claude-code-toolkit 135 agents, 35 skills, 176 plugins, hooks, MCP configs. If you want everything in one place, this is it.
8. x1xhlol/system-prompts-and-models-of-ai-tools Collected system prompts from Claude Code, Cursor, Devin, Replit, Windsurf and others. Invaluable for understanding how these tools actually work under the hood.
9. andrej-karpathy-skills A single CLAUDE.md file derived from Karpathy's observations on LLM coding pitfalls. 100k stars. Tiny file, huge impact on output quality.
10. jqueryscript/awesome-claude-code Tracks the hottest Claude Code repos by stars with short descriptions. Good for staying up to date on what the community is building.
