Dead Code Eliminator Skill

Identifies and safely removes dead code, unused functions, unreachable code paths, and orphaned files from codebases to reduce complexity and maintenance burden.

Purpose

Enable safe dead code removal for:

• Codebase simplification
• Migration preparation
• Technical debt reduction
• Build size optimization
• Maintenance cost reduction

Capabilities

1. Unused Function Detection

• Find uncalled functions
• Identify unused exports
• Detect unreferenced methods
• Map call graphs

2. Unreachable Code Identification

• Analyze control flow
• Find code after returns
• Detect impossible conditions
• Identify dead branches

3. Unused Variable Detection

• Find unread variables
