Tech Debt Cleaner

Clean up the codebase by removing duplication and dead code. If $ARGUMENTS is provided, focus on that file or directory. Otherwise, analyze the entire project.

Step 1: Find and fix duplicated code

Search for repeated logic across files — similar function bodies, copy-pasted blocks, repeated inline values, and duplicated patterns. For each instance:

• •Extract the shared logic into a reusable function or module in an appropriate location
• •Replace all occurrences with imports of the shared code
• •Preserve existing behavior exactly — no functional changes

Step 2: Find and remove dead code

Identify code that is not imported, called, or referenced anywhere:

• •Unused exports (functions, constants, types, interfaces)
• •Unused local variables and parameters
• •Unused files (not imported by any other file)
• •Unreachable code paths

Remove dead code entirely. Do not comment it out.

Rules

• •Make one focused change at a time — do not combine unrelated cleanups in a single edit
• •Verify each removal by searching for all references before deleting
• •Do not change any public API or behavior
• •Run type checking after changes if TypeScript is configured
