Christopher Meiklejohn published a technical walkthrough (52pts on HN) of using Claude as an autonomous QA agent for Android and iOS apps via screenshot-based test execution on the Zabriskie project. The system gives Claude a test plan, streams screenshots as tool results, and lets it navigate UI flows to verify behavior — no test code authoring required. The post includes specific prompting patterns and failure modes, making it a practical reference for mobile QA automation.
