What problem does it solve? Verifying that completed work actually meets requirements before merging is error-prone when done informally. This Skill runs a structured code review over a git diff in a forked context, catching bugs, security issues, and requirement gaps before they reach main. ## Core Features & Use Cases - Diff-Based Review: Compares a BASE_SHA to HEAD_SHA range and reviews every significantly modified file in full context, not just the diff hunks. - Severity-Ranked Output: Categorizes findings as Critical, Important, or Minor with file:line references, explanations, and fix guidance. - Requirements Compliance: Reads the referenced plan file and checks the implementation against stated requirements, architecture, testing, and production readiness. - Use Case: After finishing a feature task in subagent-driven development, invoke the skill with the base commit, head commit, a summary of what was implemented, and the plan path to get a clear proceed/no-proceed verdict before merging. ## Quick Start Ask the assistant to request a code review for the changes between your base commit and HEAD, describing what was implemented and pointing to the plan file.
