I browse popular GitHub projects daily to find tools that can optimize my workflow. Today, I found that half of them are part of the Claude Code ecosystem. Here are three worth checking out:

claude-code-best-practice (+2407⭐)
A compilation of 87 CC usage tips + 8 community workflow comparisons. Suitable for beginners or those who want to systematize their use after some experience.

oh-my-claudecode (+1126⭐)
An agent orchestration framework with 19 preset agents + automatic model routing (simple tasks use Haiku to save costs, complex tasks automatically upgrade to Opus). The most interesting feature is its ability to automatically extract reusable skills during debugging, so you don't have to write them manually. Ideal for those already working with CC and looking to collaborate in a team.

superpowers (+2620⭐, total stars 128K)
An agent skill framework created by Jesse Vincent, centered on test-driven development + Git worktree isolation. Suitable for those who care about code quality and don't want agents to modify code arbitrarily.

Choose based on your stage: for beginners, see best-practice; for doing actual work, check out superpowers; for team collaboration, try oh-my-claudecode.
