Spent an evening cloning shanraisshan/claude-code-best-practice and now I can't go back to my old setup. 57,590 GitHub stars. Endorsed by Boris Cherny — the engineer at Anthropic who built Claude Code. That's the kind of signal that makes you stop scrolling and actually try something. The idea is simple: one repo ships every Claude Code feature pre-integrated. Instead of hunting for subagents on one repo, slash commands on another, and hooks documentation in a blog post from three months ago, you clone this and copy two folders. Done in 30 seconds. What you get: subagents, slash commands, skills, hooks, MCP server configurations — all wired together and immediately usable. The feature I keep coming back to is /code-review. Type it with a PR open and three specialized subagents run back to back: spec-reviewer checks the diff, quality-checker lints and finds edge cases, test-driven-loop writes and runs tests. The output is severity-tagged comments and a passing test suite. It's caught real bugs for me.
