# Code Review Systematic code review methodology for consistent, effective, and humane reviews that improve both code and team culture. ## Core Principles ### 1. Review the Author, Not Just the Code Every review is a human interaction. The goal is shared understanding and team growth, not ego or gatekeeping. Be constructive, specific, and kind. ### 2. Catch Problems Early, Fix Them Forever A bug caught in review costs 10x less than one caught in production. Use each review as an opportunity to add automated checks so the same issue never needs a human review again. ### 3. Balance Depth with Velocity Deep reviews catch more issues but slow delivery. Shallow reviews miss things. Adapt depth to risk: security-critical code gets exhaustive review; trivial config changes get a quick skim. ### 4. Automate Everything You Can If a reviewer can point out a formatting issue, a lint violation, or a missing test — that check should be automated. Human attention is for design, logic, and tradeoffs. --- ## Code Review Scoring Rubric | Dimension | 1 (Poor) | 3 (Adequate) | 5 (Excellent) | |-----------|----------|---------------|----------------| | **Correctness** | Obvious bugs missed | Catches l

How do I install it?
Run `npx skills add cosmicstack-labs/mercury-agent-skills --skill code-review --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From cosmicstack-labs/mercury-agent-skills, a repository with 364 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
