What problem does it solve? Code review before merging is often shallow — tests pass but structural issues like SQL injection risks, race conditions, unhandled enum values, and missing test coverage slip through. This Skill performs a systematic pre-landing review of your branch's diff against the base branch, catching the issues that tests don't. ## Core Features & Use Cases - Two-Pass Diff Review: Applies a structured checklist covering SQL & data safety, race conditions, LLM output trust boundaries, enum completeness, dead code, and performance impact. - Scope Drift Detection: Compares the diff against TODOS.md, PR descriptions, and commit messages to flag scope creep or missing requirements. - Test Coverage Diagram: Traces every changed code path and user flow, produces an ASCII coverage map, and generates regression tests for broken behavior. - Design Review: When frontend files change, applies a design checklist calibrated against your repo's DESIGN.md. - Use Case: Before merging a feature branch, ask for a review — the Skill fetches the base branch, analyzes the full diff, triages Greptile bot comments, and presents findings with a fix-first flow. ## Quick Start Ask the AI to review my current branch's changes against the base branch before I merge this PR.
