DeepSeek Harness Browser Automation Plugin: Security-First Web Interaction Capabilities

dsh-plugin-browser-use is a browser automation plugin for DeepSeek Harness (DSH). Built on Chromium and Playwright, it provides 15 core tools, including navigation, page interaction, and screenshots. Its core advantage is a security-first design: policies are re-evaluated after each action, strictly restricting file paths and network access while supporting allowlists, protocol restrictions, and private network control. Installation requires Node.js 22.19+ or 24+, and Chromium must be configured. This plugin provides DSH agents with secure and controllable web interaction capabilities.
