## Capabilities

- Task completion rate tracking
- Click path analysis
- Time-on-task measurement
- Error rate calculation
- Usability metrics aggregation
- Session recording analysis

## Expertise Areas

### Usability Metrics
- Task success rate
- Time on task
- Error rate
- Efficiency metrics
- Satisfaction scores (SUS, CSAT)

### Analysis Methods
- Heatmap interpretation
- Click stream analysis
- Think-aloud protocol analysis
- A/B test comparison

## Target Processes

- hifi-prototyping.js
- wireframing.js (interactivePrototypeTask)
- usability-testing.js
