#claude #productivity #github #ai

Most people open Claude Code, type a question, and get an answer. That's the whole experience.

There's nothing wrong with that. But it's like buying a Swiss Army knife and only using the bottle opener.

There's an entire open source ecosystem on GitHub built around making Claude dramatically more capable. Skills that teach Claude how to handle specific types of work. Agents that let it delegate to specialized subprocesses. Frameworks that let you build AI workflows without writing code. Most of it is free.

Here are the 10 repos actually worth your time.
