What problem does it solve? Getting real user feedback on an app's UI is slow and expensive, so teams often ship interfaces without knowing where users will struggle. This Skill runs virtual user testing sessions with simulated personas to surface friction points and delight moments before real users encounter them. ## Core Features & Use Cases - Multi-Agent Simulation: Coordinates three agent personas (UX Design Expert, Content Expert, and unique Test Users) to run realistic think-aloud walkthroughs of your app's screens. - Structured Test Protocol: Runs 7 sessions covering diverse users (professionals, retirees, students) plus edge cases like VoiceOver accessibility and keyboard power users. - Synthesis Reporting: Produces per-session friction/delight logs with severity ratings and a final prioritized report separating UI issues from content/data issues. - Use Case: Before launching a new iOS app feature, run the simulation to discover that users hesitate on filter placement, then fix it before release. ## Quick Start Run a virtual UX test on my app described in the attached UI structure document and produce a synthesis report of friction points.
