Code Quality is a small category with a specific job: reviewing code rather than writing it. It holds slash-command style review skills that take a file or diff as an argument, an automated review loop that pairs Claude with a second model, professional command suites for structured workflows, and a few adjacent tools such as transcript converters and diagram redraws that made their way here through the pipeline.

The case for a review skill is that Claude reviewing its own work with no instructions reads like a compliment. A structured review skill asks the questions you would ask (correctness, error handling, naming, tests) and reports in the same shape each time, which makes the output comparable across pull requests. A review loop is for teams that want a second opinion on every change without a human in the loop for the first pass.

A skill installs as ~/.claude/skills/<name>/SKILL.md, with the command on its entry page. Review skills are among the safest to add, since they read more than they write, but check whether one shells out to another model and what it sends there. Open a new session and invoke it by describing what you want reviewed.
