| What makes it different | - Provides real runtime evidence to AI agents instead of requiring them to guess or generate test cases
- Runs completely locally with zero code changes needed to the codebase
- Proves fixes work by re-executing against acceptance tests the agent never sees
- Works with any AI coding agent without requiring new subscriptions or API keys
- Uses published scientific methods for each decision, with full math and attribution transparency
| - Conversational assessment tests actual AI usage rather than recall through quiz-style questions
- High score reliability with 98% of retakers landing in same or adjacent tier
- Completely free assessment, report and certificate with no gating or upsell required
- Anti-gaming design with separate conversation and scoring systems plus integrity checks
