Tool Cognitive Journey Init
Category: Cognitive Journeys -- Tier: All
Start a cognitive user journey simulation. Returns the persona's cognitive profile, initial state, and abandonment thresholds.
The LLM drives the actual simulation using browser tools (navigate, click, fill, screenshot). It tracks cognitive state throughout.
When to Use
Cognitive journeys simulate real user behavior. They use 26 cognitive traits and 10 motivational values. The simulation tracks patience, frustration, confusion, decision fatigue, and emotional state. All of this is grounded in cognitive psychology research.
