Codebase Cleanup

Systematic code cleanup across 11 quality dimensions, ordered by risk. Each finding includes confidence scoring (HIGH/MEDIUM/LOW) and all changes are verified through build/test gates.

Environment Detection

!git rev-parse --show-toplevel 2>/dev/null && echo "---" && git diff --stat HEAD~5 2>/dev/null | tail -5 !ls package.json pyproject.toml Cargo.toml go.mod Makefile 2>/dev/null | head -5 !cat package.json 2>/dev/null | head -3; echo "---"; ls tsconfig.json .eslintrc* 2>/dev/null

Prerequisites

• Git repository with clean working tree (no uncommitted changes)
• Language toolchain installed (Node.js/Python/Go/Rust as applicable)
• Optional: knip, madge, jscpd, ruff, bandit for tool-verified scanning

Overview

This skill orchestrates cleanup across 11 dimensions, each with a dedicated agent. Dimensions are ordered LOW → HIGH risk. See dimensions reference for full detection criteria, verification steps, and risk profiles.

The 11 Dimensions (by risk level):

#	Dimension	Key	Risk	Auto-apply?
1	Dead code removal	dead	LOW	Yes (after build)
2	AI slop removal	slop	LOW	Comments only
3	Weak type elimination	types	MED	Yes (after typecheck)
4	Security cleanup
