Find and Report Dead Code

Scan the codebase for dead code and unused exports:

1. Identify unused exports:

   • Functions not called within the module or by external modules
   • Classes with no instantiations
   • Constants/variables not referenced
   • Type definitions not used

2. Detect unreachable code patterns:

   • Statements after return/throw
   • Unreachable branches in conditionals
   • Dead try-catch blocks
   • Unused catch parameters

3. Analyze file-level patterns:

   • Modules that are never imported
   • Test files without corresponding implementation
   • Example/demo code in main codebase
   • Deprecated or marked-for-removal code

Generate a comprehensive report with:

• Dead code segments (with file locations and line numbers)
• Confidence level for each finding (high/medium/low)
• Safe-to-remove vs requires-review items
• Estimated code reduction if cleanup is done

Safe removals candidates:

• Variables only assigned, never read
• Functions declared but never called
• Exported items with no external references

Requires review:

• Code that might be called dynamically
• Public APIs (check if external consumers exist)
• Backwards-compatibility concerns

Use plan mode to suggest removals without applying them.
