SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Cleaning up freshly written code is tedious and easy to skip, and a single broad review pass often misses duplication, quality issues, or inefficiencies hiding across files. This Skill runs three focused reviewers in parallel over your git diff and applies the safe fixes for you. ## Core Features & Use Cases - Parallel Three-Agent Review: Launches reuse, quality, and efficiency reviewers concurrently, each searching the full codebase for evidence rather than reasoning from the diff alone. - Risk-Tiered Fix Application: Classifies findings as SAFE (auto-apply), CAREFUL (apply with test verification), or RISKY (flag for human review), then applies them in order with test runs after each step. - Flexible Scoping and Dry Run: Supports focusing on one reviewer category, reviewing staged changes, the last commit, a branch, or specific files, and a report-only mode that changes nothing. - Use Case: After finishing a feature branch, ask to simplify your changes; the Skill captures the diff, finds duplicated utilities, redundant state, and N+1 patterns, applies the safe cleanups, runs the targeted tests, and summarizes what changed. ## Quick Start Ask the agent to simplify my recent uncommitted changes and report anything risky without applying it.

FAQPage Schema
How do I review and clean up my recent code changes automatically?▼

Ask the agent to simplify your changes. It captures the relevant git diff, runs three parallel reviewers covering reuse, quality, and efficiency, then applies safe fixes automatically and verifies them with the project's tests.

How to review code changes without modifying anything?▼

Request a dry run by saying simplify but do not change anything. The three reviewers still run and report findings across all risk tiers, but no edits are applied until you approve them.

Can I review only the last commit or specific files?▼

Yes, you can scope the review to staged changes, the last commit, a branch diff against main, or named files. The Skill selects the matching git diff command based on what you ask for.

What kinds of fixes get applied automatically versus flagged?▼

SAFE fixes like unused imports and commented-out code are auto-applied. CAREFUL fixes like renames and extracted helpers are applied with test verification. RISKY changes like public API renames or N+1 restructuring are only flagged for human review.

What are the limitations of parallel multi-agent code review?▼

Very large diffs over roughly 2000 lines become token-heavy since each reviewer carries the full diff, so scoping down is recommended. Findings without concrete file and line evidence are discarded, and dead-code tool reports are verified by grep before removal.
