Techdebt

Technical Debt Cleanup

Finds and cleans up technical debt in the codebase before ending a session.

Inspection Items

1. Duplicate Code

• Check if similar functions/logic exist across multiple files
• Identify code that could be extracted into common utilities

2. Unused Code

• Unused import statements
• Unused variables/functions
• Commented-out code blocks

3. Debug Code

• console.log / console.error
• debugger statements
• Temporary comments (// TODO, // FIXME, // HACK, // XXX)

4. Code Quality

• any type usage (TypeScript)
• Hardcoded values (magic numbers/strings)
• Functions that are too long (over 50 lines)
• Deep nesting (over 4 levels)

# Find TODO comments
grep -rn "TODO\|FIXME\|HACK\|XXX" --include="*.ts" --include="*.tsx" src/
