On-demand complexity hunting. This skill finds what to delete and reports it; it never applies the fixes. Correctness bugs, security holes, and performance go to a normal review pass (code-review-policy owns those) - this one only cuts complexity. The build-time discipline that prevents the bloat in the first place lives in anti-overengineering-policy.
Anti Overengineering Review is a community-contributed Claude Code skill in the performance sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/anti-overengineering-review/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when the user says "review for over-engineering", "what can we delete", "is this over-engineered", "simplify review", "audit this codebase", "find bloat", "what did we defer", "list the shortcuts", or "what did we mark to do later". Complements code-review-policy (which owns correctness, security, and performance); this one only cuts complexity.
The Anti Overengineering Review Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 159,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
