Dev Browser is a browser automation skill/plugin that enables an AI agent to control a real browser for verification and testing during development. Its purpose is to close the gap between “code was written” and “the UI actually works,” by letting the agent navigate, interact with pages, and validate behavior in a live environment. A key idea is persistence: the browser can keep pages open so the agent can navigate once and then perform multiple interactions across scripts without losing state each time. It supports flexible execution modes, allowing full-script runs when tasks are straightforward and step-by-step exploration when the agent needs to inspect or iterate carefully. To make automation more reliable for language models, it provides LLM-friendly DOM snapshots that structure the page in a way that is easier for an agent to interpret than raw HTML dumps.
