Best Claude skills for Coding
Coding skills change how your agent works, not only what it writes: brainstorm before building, write a plan, test first, review its own diff, and finish branches cleanly. Packs like Superpowers, Matt Pocock's skills, Addy Osmani's agent skills and Garry Tan's gstack are the most starred skills on GitHub.

Skills that compose: planning, testing and review that hand off to each other.
