What problem does it solve? Reviewing code changes by hand is slow and error-prone, and informal reviews often miss security, regression, or concurrency issues buried in a diff. This Skill enforces a disciplined review contract that inspects only the requested Git diff and reports verified, actionable findings. ## Core Features & Use Cases - Scoped Diff Review: Reviews the current working-tree diff by default, or validates and reviews a specified local Git range. - Evidence-Backed Findings: Every finding includes a title, exact file and line evidence, impact, and a concrete remediation direction, ordered by severity. - Safety Guardrails: Redacts secrets and credentials from findings, never edits files or Git state, and leaves all follow-up decisions to the user. - Use Case: Before merging a feature branch, ask for a review of the staged changes and receive a severity-ordered list of correctness, security, and performance issues with exact line references. ## Quick Start Review my current working-tree diff and report only actionable findings with file and line evidence.
