Code Review Claude Skills

2 032 code review skills from 387 authors. They read someone else's code and work through changes before those land. Half of them fit into 1 560 tokens or less — that is what one costs your context window when the agent loads it. 210 ship runnable scripts rather than instructions alone. 3 of them cannot work without an MCP server, most often rube. We also found 250 copies of these same skills sitting in other people's repositories — counted once here, not 250 times.

Semgrep is the right tool for pattern-based code scanning across 30+ languages.
