What problem does it solve? Catching structural defects like SQL injection, race conditions, shell injection, and unvalidated LLM output before code lands is time-consuming and error-prone when done manually. This Skill automates pre-landing PR review by analyzing the diff against the base branch with a structured, severity-tiered checklist. ## Core Features & Use Cases - Two-Pass Diff Review: Runs a CRITICAL pass (SQL & data safety, race conditions, LLM output trust boundary, shell injection, enum completeness) followed by an INFORMATIONAL pass (async/sync mixing, type coercion, CI/CD pipeline issues, and more). - Parallel Specialist Subagents: Dispatches dedicated checklists for testing gaps, maintainability, security, performance, data migrations, API contracts, and an adversarial red-team pass on large diffs. - Fix-First Workflow: Auto-applies mechanical fixes (dead code, N+1 queries, magic numbers) while batching genuinely ambiguous findings into a single structured user decision. - Greptile Comment Triage: Fetches, classifies, and replies to Greptile bot review comments on GitHub PRs with evidence-backed responses. - Use Case: Before merging a feature branch, ask for a pre-landing review; the Skill inspects git diff origin/main, flags a missing eager-load causing N+1 queries, auto-fixes it, and asks you to confirm a race-condition fix. ## Quick Start Ask the assistant to review this PR or run a pre-landing review of my current diff against the base branch.
