Want help applying this to your idea? Tell me what you are trying to build and where you are stuck.

Claude Code out of the box is powerful. Claude Code with the right GitHub repos is unstoppable. After testing over 200 repositories, we narrowed it down to 10 that genuinely move the needle. Each installs with a single command, and together they transform Claude Code from a smart assistant into a complete AI development team.
