Does it provide code examples for the suggested fixes?

Absolutely. The skill provides concrete code blocks and 'before-and-after' examples to show you exactly how to implement its recommendations.

How are the review findings prioritized?

Findings are ranked into three tiers: Critical (bugs/security), Important (performance/design), and Nice-to-have (style/formatting) to help you prioritize your workflow.

How do I activate the Code Review Expert skill?

The skill activates automatically whenever you ask Claude to review, refactor, debug, or analyze code. There is no need for explicit commands.

Can it find security vulnerabilities?

Yes, security is a primary focus. It checks for common risks such as weak cryptographic algorithms, insecure inputs, and potential exploits.

Which programming languages does this skill support?

This skill is language-agnostic and works across all major programming languages supported by Claude, including Python, JavaScript, Java, C++, and more.
