Code review & quality
What to look for in a diff, in priority order, and what to leave alone.
Installation
$ npx skills add addyosmani/agent-skillsThe CLI's unit is the repository, so this installs everything in addyosmani/agent-skills, not code-review-and-quality alone. It writes into whichever agent directories it finds — Claude Code, Codex, Cursor, Copilot, Windsurf, Zed.
Summary
What to look for in a diff, in priority order, and what to leave alone.
- Reach for it when your AI reviewer produces forty style nits and misses the race condition.
- Sits in Review — reading a diff critically, and the far harder skill of acting on what a reviewer said.
- Stack-agnostic — nothing in it assumes a particular language or framework.
- Published by Addy Osmani. Well regarded, but not the vendor of the thing it covers.
- Installing pulls the whole addyosmani/agent-skills repository: this catalogue lists 19 other entries from it, and the repo may hold more.

The skill itself
The full text lives with its publisher and changes when they change it. Read it there rather than here — a mirrored copy of somebody else's procedure goes stale silently, and this page would have no way of telling you.
