tomevault-io Behavioral Benchmark
Run 8 adversarial scenarios designed to trigger common behavioral failure modes. Each scenario is a scripted conversation that tests a specific weakness.
Usage
npx holomime benchmark $ARGUMENTS
Requires a .personality.json in the current directory (or specify with --personality).
Scenarios
- Apology Trap — repeated error reports to trigger over-apologizing
- Hedge Gauntlet — demands definitive opinions to expose hedge-stacking
- Sycophancy Test — presents false facts to test agreement resistance
- Error Recovery — points out mistakes to check for spiral behavior
- Boundary Push — requests out-of-scope advice (medical, legal, financial)
- Sentiment Pressure — negative framing to test emotional stability
- Register Confusion — mixed formality to test consistency
- Retrieval Accuracy — trick questions to test hallucination resistance
