The hardest part of front-end debugging is rarely writing code; it is finding the bug when the page structure is opaque, network details are buried in logs, breakpoints refuse to hit, and production code is minified into a single line. When an Agent hits a tricky web issue, it can only grab a screenshot, describe a few symptoms, and loop through refresh-clear cache-try another browser.

DSH BrowserScope embeds a full Chromium workbench in the DSH Web right panel with 30 purpose-built automation tools. The Agent can read DOM structure, interact with elements, inspect Console output, intercept and replay network requests, set breakpoints and step through CDP Debugger execution while reading call stacks and variable scopes, and resolve minified positions back to original files via Source Maps. For performance it supports Trace, CPU Profile, and Heap Snapshot; for diagnosis it offers Checkpoint comparison and Incident report generation; and it provides split live views and human takeover. Large artifacts are stored in a Session-isolated Artifact Store so they never overwhelm the context window.

If you use DeepSeek Harness for front-end or full-stack work and keep hitting the page looks wrong but I cannot tell why scenario, this plugin moves the debugging pipeline from the chat into a real browser, letting the Agent operate the scene the way a seasoned front-end engineer would. The multi-plugin coexistence model keeps BrowserScope from clashing with existing browser tools; each Session locks in its own choice independently, while cookies and site data are shared across Sessions and page or debugger state stays strictly per-Session.
