Scope the diff with git diff for unstaged work or git diff --cached for staged work, then review for duplication, inefficiency, and clarity problems. This Skill automates that by running four parallel review passes and merging structured findings.

Apply only high-confidence, behavior-preserving fixes such as removing dead code, replacing duplication with existing helpers, and simplifying control flow. The safe-fixes mode skips subjective refactors and keeps edits scoped to the reviewed files.

Yes, the fix-and-validate mode runs the smallest relevant validation after edits, such as targeted tests, typecheck, or lint for the touched scope. It prefers fast, scoped validation over full-suite runs.

Yes, before reviewing or fixing, the Skill reads local instruction files like AGENTS.md and relevant project docs for the touched area. This distinguishes real issues from intentional local patterns.

Avoid it when changes need product or architectural judgment, when there is no clear diff scope, or when environment-specific testing is required. The Skill stops and asks for clarification if scope or success criteria are missing.
