Tech Debt Finder

Identify duplicated code, inconsistent patterns, and refactoring opportunities.

When to Use

"Find duplicate code"
"What needs refactoring?"
"Are there inconsistent patterns?"
Code review prep
Pre-refactor analysis

Detection Process

Scan - Grep for common debt indicators
Cluster - Group similar issues
Prioritize - Rank by frequency × impact
Report - Show findings with locations

Quick Patterns

Debt Type	Detection Method
Duplicated code	Hash-compare function bodies
Similar-but-diff	Fuzzy match on structure
Inconsistent naming	Regex for mixed conventions
Dead code	Unreferenced exports/functions
TODO/FIXME	Grep for comment markers
Magic numbers	Literals outside const/config
Long functions	Line count > threshold
Deep nesting	Indentation level analysis

Output Format

## Technical Debt Report

### High Priority (fix soon)
- [DUPLICATE] src/utils/format.ts:23 ↔ src/helpers/fmt.ts:45
  Similar: 87% | Impact: High (called 12 places)

### Medium Priority (plan for)
- [INCONSISTENT] Mixed naming: getUserData vs fetch_user
  Files: api.ts, service.ts, handler.ts

### Low Priority (track)
- [TODO] 23 TODO comments, oldest: 2023-01-15
