Pattern: Coding Agents Are Gaining Runtime 'Sight' — Browser/DevTools Observability Becomes a Standard Layer
Chrome for Developers·medium signal
The throughline across chrome-devtools-mcp 1.0 and browser-automation kits (browser-use, OpenCLI) is that agents are being given the ability to observe what their code actually does at runtime — inspect a live DOM, read console/network, run Lighthouse — rather than only emitting source. This closes the verification gap that causes agents to confidently ship broken UI. Expect 'agent can see the running app' to become a baseline expectation for front-end and full-stack agent workflows, the same way file search became table stakes.
