A guide to building a lightweight AI QA agent for Expo/React Native apps using EAS Workflows and the agent-device library. The setup automates mobile UI verification on both Android and iOS for every pull request: it reuses existing builds, boots emulators/simulators, lets an AI agent inspect the UI via accessibility tree and screenshots, and posts a concise QA summary as a GitHub PR comment. The key design principle is splitting deterministic bootstrap steps (install, launch) from the variable agent-driven inspection phase to maximize reliability. The agent itself stays minimal using Vercel's AI SDK, and the whole pipeline can be started from a provided open-source template in minutes.
