dsh-browser-annotate: A Browser Annotation Tool Integrated with Real Chromium

`dsh-browser-annotate` is a browser interaction plugin for DeepSeek Harness (DSH), designed to address the lack of intuitive feedback and advanced debugging capabilities in agents. It provides a real Chromium environment and CDP access through an Electron desktop app, supporting 12 operational tools, including navigation, screenshots, clicking, dragging, popup handling, and custom code execution. A key feature is its right-click annotation mechanism, which lets users enqueue element information—such as selectors, screenshots, and styles—and inject it into the conversation, with a dual-pane layout and local communication support. Installation requires DSH plugin commands. Known limitations include the inability to close tabs automatically and the lack of support for creating new browser contexts.
