Your coding agent can build a lot of React Native code, but verification still falls heavily on the developer. This talk shows a technique that closes that loop: leverage the fact that Expo can build to web, expose stable test IDs and helper APIs, and create a custom CLI that uses Chrome CDP so the agent can work with the web version of the app while it codes. The agent can inspect state, query the DOM, emulate mobile viewports, capture screenshots, check network logs, and run real product workflows without waiting for a human to describe the problem.

Attendees will learn how to create app-specific debug CLIs that let agents verify frontend behavior, application state, backend state, and React performance reports, then use those checks to debug and optimize the app.
