DeepSeek Harness (DSH) is a local AI programming environment. During development, frequently switching windows to the web-based chat.deepseek.com for conversations can interrupt the workflow. The dsh-deepseek-chat-embed plugin is designed to deeply integrate the official chat page into the DSH desktop client, providing a dual-entry chat panel and persistent login sessions to address the pain point of switching between multiple tasks.

Core Features

The plugin follows a strategy pattern architecture and provides native solutions for different desktop environments.

  • Dual-entry architecture
    • Left navigation main panel: Expands in an immersive full-screen view in the central session area, suitable for long consultations or in-depth planning.
    • Right sidebar: Displays side by side as a native Tab, suitable for quick reference while writing code or checking the terminal.
  • Multi-desktop client support
    • Supports the official DSH desktop version (Electron) and DSH Dock (Tauri v2).
    • Supports the generic native multi-window protocol; third-party desktop shells (such as Wails and Qt) can also integrate through standard interfaces.
  • Host and guest page interaction
    • Implements bidirectional mutual exclusion and smooth collapsing between the guest page and the host sidebar. When the guest page is expanded, the host sidebar automatically collapses; when the guest page is collapsed, the host sidebar smoothly expands.
    • Uses CSS linear interpolation along the same track to eliminate layout shifts.
  • Robustness design
    • Non-invasive DOM adaptation: Locates nodes using structural and semantic heuristics, without relying on hardcoded class names, and remains resilient to front-end site updates.
    • Network isolation protection: Manages the TCP connection pool under high-concurrency scenarios to prevent page freezes.
    • Test assurance: Includes 100 automated contract regression tests.
