What aspects of the code does this skill review?

It reviews code for correctness, logic errors, security vulnerabilities, performance efficiency (including database queries), architectural design, and test coverage.

Can it detect performance issues like N+1 queries?

Specifically, yes. The review checklist includes checks for inefficient database queries, missing indexes, and unbounded data fetching.

Will it help ensure my code is well-tested?

Absolutely. The skill verifies that new features have corresponding tests, bug fixes include regressions, and overall test quality meets professional standards.

Does it integrate with my existing Git workflow?

Yes, the skill is designed to use 'git' and 'gh' commands to view diffs, read PR descriptions, and understand commit history directly in your environment.

How does it categorize feedback?

Feedback is structured into four tiers: Critical Issues (blocking), Important Issues (should fix), Suggestions (nice-to-have), and Positive Feedback (calling out good work).
