dead-code-auditor

Purpose

Surface code that exists but is never executed or referenced. Dead code increases maintenance burden, confuses readers, and masks real complexity. This skill finds it and ranks it by removal impact.

Trigger

Apply when:

• "dead code", "unused code", "zombie functions", "unreachable code"
• "find unused exports", "unused imports", "死碼", "未使用的程式碼"
• Pre-cleanup sprint, post-migration cleanup, repository health audit

Do NOT trigger for:

• General code quality analysis — use code-quality instead
• Technical debt prioritization — use tech-debt-tracker instead
• Dependency vulnerabilities — use dependency-auditor instead
