5 Best GitHub Repositories for AI Agent Skills

npx skills add addyosmani/agent-skills

Or browse the skills first:

npx skills add addyosmani/agent-skills --list

You can also install individual skills:

npx skills add addyosmani/agent-skills --skill test-driven-development

The Skills CLI supports 70+ coding agents, including Claude Code, Cursor, Codex, Copilot, and Cline.

After going through these collections, what I like most is how different the approaches are.

Superpowers gives you a full engineering methodology, Matt Pocock keeps things small and composable, ECC turns the coding agent into more of an engineering platform, Awesome LLM Apps focuses on experimentation, and Addy Osmani brings everything back to production-quality software.

For me, the best approach is not to install everything. I would pick the workflows that actually match how I work, test them on real projects, and then customize the SKILL.md files over time.

That is where agent skills become really useful: you are not just making the agent smarter, you are teaching it how you want software to be built.
