# Technical Debt Quantifier Skill

Measures, categorizes, and prioritizes technical debt to support informed decision-making for migration planning and debt remediation strategies.

## Purpose

Enable technical debt management for:
- Debt categorization and inventory
- Remediation effort estimation
- Interest calculation (ongoing cost)
- Priority scoring
- Trend tracking

## Capabilities

### 1. Debt Categorization
- Code debt (smells, complexity)
- Architecture debt (coupling, cohesion)
- Test debt (coverage gaps)
- Documentation debt
- Infrastructure debt

### 2. Remediation Effort Estimation
- Estimate fix time per item
- Calculate total remediation cost
- Identify quick wins
- Plan sprint allocation

### 3. Interest Calculation
- Calculate ongoing maintenance cost
- Estimate productivity impact
- Project future debt growth
- Model compound interest

### 4. Priority Scoring
- Score by business impact
- Weight by risk level
- Factor in remediation cost
- Calculate ROI of fixes

### 5. Debt-to-Value Ratio
- Compare debt to feature velocity
- Benchmark against industry
- Track debt percentage
- Set organizational targets

### 6. Trend Tracking
- Monitor debt over time
- Track remediation progress
- Identify debt sources
- Report debt velocity
