cleanup-code
Comprehensive codebase cleanup across 11 quality dimensions: dead code, duplication, weak types, circular deps, defensive cruft, legacy code, AI slop, type consolidation, security, performance, and async patterns. Analyzes code with confidence scoring and verifies changes with build/test gates. Use when codebase has accumulated tech debt, after major feature work, before releases, or when code quality metrics are declining. Trigger with "/cleanup-code-code", "clean up the codebase", "remove dead code", "fix code quality".

# 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)
