You write a goal in plain language (\"I want to sign up and create my first list\", \"delete my account\", \"find a vegetarian restaurant near me and save it\") and a persona (\"first-time user, never seen this app\"). Harness builds (or just launches) your target, and an LLM agent reads screenshots, clicks/types/scrolls, and pursues the goal — narrating what it sees, flagging UX friction (dead ends, ambiguous labels, unresponsive controls), and stopping when it succeeds, fails, or would give up. Three artifacts come out of every run: 1. Did the goal complete? — success / failure / blocked + summary 2. What was the path? — replayable sequence of screens + actions 3. Where was the friction? — timestamped events the agent flagged as confusing Targets Kind How Harness drives it --- --- iOS Simulator xcodebuild your project + scheme; simctl boot/install/launch; WebDriverAgent for input. macOS app NSWorkspace launch (pre-built .app or xcodebuild macOS scheme); CGEvent for input; CGWindowListCreateImage for capture.
