What it does

The skill gives an agent a code review rulebook for two dozen languages and frameworks, including React, Vue, Angular, Svelte, Rust, TypeScript, Java, PHP, Ruby, Python, Go and more. Rules are split by topic: architecture, performance, security audit, code quality and common bugs. Material loads progressively to save context: a compact SKILL.md on activation, with detailed stack sections opened on demand. The review tone is collaborative: questions over commands, suggestions over mandates.

Who it is for. For developers and reviewers who want a single review standard across stacks.

Good fit when

You need to review a pull request or code changes
You need a shared review checklist for a team
You need an architecture, performance or security review

Not a fit when

You need linters and tests run automatically rather than rule-based review
Your stack is outside the skill's coverage

Example request

Review this pull request and flag security and performance risks

Limitations

The skill gives rule-based guidance; it does not run builds or tests itself. Coverage depth varies by language, and references are in English.

How to disable. Remove the code-review-skill folder from your agent's skills directory, for example ~/.claude/skills/code-review-skill.

Security check

The skill is rules and references, reading code and giving feedback

README in short

The README describes a code review skill for Claude Code and compatible agents with coverage of over twenty languages and frameworks and a large body of rules. Material loads progressively to avoid overfilling context. Install via npx skills add or by manually cloning into a skills directory, with an option to wire it into a plugin. The review tone is collaborative. MIT licensed.
