Constraints

Prerequisites: DeepSeek Harness (DSH) CLI is installed, Node.js meets ^22.19.0 or >=24.0.0, and pnpm meets ^11.0.0. The target profile defaults to web; replace web with your actual profile if different. After installation, restart the DSH Web instance and hard-refresh the browser. Do not enable alongside ds-bot due to layout conflicts.

What they did

MichengAI released DSH Codex UI v2.0, a community-maintained interface enhancement suite for DeepSeek Harness Web. The suite rearchitects the frontend through six decoupled sub-plugins: input history recall (composer), full-screen dual-island settings panel (settings-skin), 7 native glass themes (theme), modular draggable sidebar (sidebar), semantic auto-generated session titles (session-title), and centralized companion plugin management (dependencies). Version 2.0 completely abandoned the 1.x invasive DOM override approach in favor of official native primitives and Slots, achieving zero-intrusion micro-kernel decoupling.

How it went

The author reports the plugin verified on multiple DSH 0.2.x builds (>=0.2.0-rc.1 <0.3.0-0), including 0.2.0-rc.1 through 0.2.2-alpha.2, with claimed automatic forward compatibility for subsequent RCs. It offers 7 built-in themes, dual layout modes (Stock Flat / Mica Floating), 3 material presets, and ground glow toggle. Input history is workspace-isolated with up to 200 items. (author_report)

Worth knowing

1. Do not enable alongside ds-bot; both redesign sidebar and session slots with overlapping layout mechanics. 2. Requires Node.js ^22.19.0 || >=24.0.0 and pnpm ^11.0.0; DSH CLI must be pre-configured. 3. After installation, you must restart the DSH Web instance and hard-refresh the browser; a normal refresh may fail to load new themes and components. 4. Source does not provide uninstall commands or rollback steps; manual dsh plugin remove may be needed. 5. Not tested by this site; actual compatibility may vary with DSH version iterations. 6. Screenshots and feature descriptions are from author claims, unverified.

Steps

  1. Run the install command

    In PowerShell, MSYS Bash, or any terminal with DSH CLI available, run the following command to install Codex UI into the specified profile (example uses web). Replace web with your actual profile if needed.
