dsh-code-ide

When using DeepSeek Harness for AI-assisted programming, constantly switching between the chat interface and a local editor can disrupt your workflow. dsh-code-ide solves this by adding a fully-featured, browser-based IDE workspace as an optional native tab. It allows you to interact with your workspace code directly within the same browser window, creating a seamless loop between AI conversation and code editing without ever leaving the session.

Drawing inspiration from VS Code, the plugin features a multi-tab editor powered by CodeMirror 6, complete with syntax highlighting for dozens of languages, robust search-and-replace capabilities, and rich previews for Markdown and media files. It also includes a lazy-loading file explorer with platform-aware security probes and a multi-session xterm.js terminal. Deeply integrated with Harness, it automatically syncs workspace contexts, themes, and language settings, while enforcing strict same-origin security boundaries to protect your local environment.

This plugin is perfect for developers who prefer a browser-centric workflow or those who want to instantly review, tweak, and test AI-generated code right inside the Harness interface. It delivers a lightweight yet powerful web IDE experience, enabling you to manage files and run terminal commands without compromising local security.
