What problem does it solve? Reviewing git history without a clear goal leads to aimless browsing and missed issues. This Skill enforces a purpose-driven review workflow that traces changes, checks commit coherence, and surfaces scope drift, undocumented breaking changes, and non-atomic commits. ## Core Features & Use Cases - Purpose-First Review: Requires declaring what you are investigating before touching history, keeping the review focused. - Three Review Modes: SUMMARY for scanning recent history, SEARCH for finding relevant commits by message, file, or code change, and EXPAND for examining specific commits in detail. - Coherence Checklist: Assesses scope alignment, API consistency, breaking changes, debt tracking, and commit atomicity, then outputs a structured report with findings, concerns, and recommendations. - Use Case: Before modifying an authentication module, use this Skill to trace how it evolved, find where the API contract changed, and verify each change was justified and documented. ## Quick Start Ask the agent to run a git review tracing how the authentication module evolved over the last month and flag any commits whose changes do not match their messages.
