SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Code reviews are time-consuming and easy to get wrong when reviewers miss regressions buried in large diffs or flag noise instead of real defects. This Skill performs a read-only, defect-first review of a specified change and returns only findings the author would likely fix. ## Core Features & Use Cases - Defect-First Review: Inspects the complete diff and surrounding code to identify concrete regressions affecting correctness, security, performance, or maintainability. - Base-Branch Comparison: Resolves the correct merge-base against the branch upstream so reviews reflect what would actually merge, not a stale branch tip. - Prioritized Findings: Returns findings ordered by severity using P0-P3 priorities with file and line citations, plus an overall assessment and test-gap notes. - Use Case: A lead agent finishes implementing a feature and delegates review of the uncommitted changes; this Skill inspects the diff, verifies each finding against tests and call sites, and reports only actionable defects. ## Quick Start Use the review-agent skill to review my uncommitted changes and return every actionable finding.

FAQPage Schema
How do I review uncommitted code changes with an AI agent?

Delegate the target to the review-agent skill, which inspects the full diff and surrounding code, then returns prioritized findings with file and line citations. It performs a read-only review and never modifies files or creates commits.

How does the review agent compare against a base branch?

It resolves the comparison ref to the branch's upstream when available, runs git merge-base HEAD against that ref, and inspects the diff from the merge-base. This reviews what would actually merge rather than diffing against the branch tip.

What kinds of issues does this code review flag?

It flags discrete, actionable defects affecting correctness, security, performance, or maintainability that were introduced by the reviewed change. It skips speculative concerns, pre-existing problems, intentional behavior changes, and style nits.

Can the review agent modify files or post review comments?

No. The skill is strictly read-only: it cannot modify files, create commits, push branches, post review comments, or delegate the review to another agent. It only inspects the target and reports findings.

What happens when a code review finds no defects?

The skill reports "No findings." rather than inventing issues to fill the result. It still adds a brief overall assessment and mentions any material test gaps or residual risks.
