8 tools in this category.
Simulate real user behavior with 26 cognitive traits and 10 motivational values. Track patience, frustration, confusion, decision fatigue, and emotional state. Includes Wasserstein-based cognitive distance, persona interpolation via geodesics, adversarial persona generation, and cognitive load estimation.
New in v18.27-29: Cognitive Optimal Transport treats persona traits as probability measures. Journey validation now includes goal evidence verification and step-by-step path logging.
Tools
| Tool | Description |
|---|---|
cognitive_distance |
Compute the Wasserstein cognitive distance between two personas. Returns W₁ distance (true cognitive distance), per-trai |
cognitive_coverage |
Select the N most cognitively different personas from a list for maximum test coverage. Uses greedy farthest-point sampl |
cognitive_interpolate |
Generate an interpolated persona between two known personas using Wasserstein geodesic. Preserves trait coupling structu |
cognitive_load_estimate |
Estimate cognitive load for a specific persona on page metrics. Returns per-dimension breakdown (information, visual, at |
cognitive_journey_init |
Initialize a cognitive user journey simulation. Returns the persona's cognitive profile, initial state, and abandonment |
cognitive_journey_update_state |
Update the cognitive state during a journey simulation. Call this after each action to track mental state. |
list_cognitive_personas |
List all available personas with their cognitive traits (includes accessibility and emotional personas) |
cognitive_journey_autonomous |
Run a complete cognitive journey server-side using your stored API key. Requires set_api_key first. |
