SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Recent code changes often accumulate duplication, needless complexity, wasted work, and shallow band-aid fixes that a single broad review misses. This Skill runs four focused reviewers in parallel over your git diff, aggregates their findings, and applies the safe fixes so cleanup happens in one pass instead of four sequential reviews. ## Core Features & Use Cases - Parallel 4-Agent Review: Fans out reuse, quality, efficiency, and altitude reviewers concurrently via delegate_task batch mode, each searching the full codebase for evidence with git blame and grep. - Risk-Tiered Application: Auto-applies SAFE fixes (unused imports, dead code), verifies CAREFUL refactors with tests, and flags RISKY changes (public API renames, N+1 restructuring) for human decision. - Flexible Scoping: Supports focus modifiers (reuse, quality, efficiency, altitude), dry-run report-only mode, and diff scoping to staged changes, last commit, branch, or specific files. - Use Case: After finishing a feature branch, say "simplify my changes" to get duplication removed, nested conditionals flattened, and band-aid fixes flagged with deeper root-cause alternatives before opening the PR. ## Quick Start Ask the agent to simplify my recent changes and it will review the current git diff with four parallel reviewers and apply the safe cleanup fixes.

Frequently Asked Questions about simplify-code

High-intent search queries and answers about installing and using this skill.

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

Run the simplify command on your git diff and four parallel reviewers will scan for duplication, quality issues, inefficiency, and shallow fixes. Safe fixes like unused imports are auto-applied, while risky changes are flagged for your review with test verification after each edit.

What is the difference between code cleanup and code review?▼

Cleanup improves code that already works by removing duplication, flattening complexity, and deepening band-aid fixes. Code review hunts for correctness bugs and security issues before commit. This Skill handles cleanup only and reports any bugs found as separate notes.

Can I run a code review without applying any changes?▼

Yes, request a dry run by saying "simplify but don't change anything" or "just report". The four reviewers still analyze the full diff and present findings grouped by risk tier, but nothing is applied until you approve.

Does parallel code review work without subagent delegation?▼

Yes, when delegate_task is unavailable the Skill falls back to working through all four reviewer angles sequentially in the current context with the same search standards. The final summary clearly states it was a single-pass inline review rather than the parallel fan-out.

When should I not use automated code simplification?▼

Avoid it on very large diffs over roughly 2000 lines without scoping down first, since four subagents each carrying the full diff is token-heavy. Also do not auto-run it after every edit; invoke it only when explicitly requested.

Why does dead code removal sometimes break working code?▼

Tools like knip and ts-prune flag exports that are actually used dynamically through string-based imports or reflection. The Skill requires grepping for the symbol name and checking git blame before removal, and tags public-contract changes like API routes as RISKY.
