HUD Floating Bar

An always-on-top floating HUD chat bar for DeepSeek Harness: live session transcript (markdown rendering, streaming output), workspace / session / model / reasoning-effort switching, and Picture-in-Picture (PiP) detach — pop the HUD into an OS-level always-on-top window (Chrome/Edge), usable over any other app.

简体中文

Official bundle plugin for DeepSeek Harness.

Features

• Floating HUD bar — draggable, resizable, always-on-top overlay inside the web UI
• Live transcript — realtime conversation with markdown rendering and streaming cursor; tool calls shown compactly
• Switchers — workspace / session / model (grouped by provider) / reasoning effort, also inline above the composer
• Send / Stop generating — the primary button turns into 停止生成 while the agent is running, like the main web composer
• Approval notice — a banner appears when any session awaits a permission approval, telling you to approve in the main UI
• Picture-in-Picture detach — Chrome/Edge 116+: pop the HUD into an OS-level always-on-top PiP window; works across other apps
• Pin / follow — pin the HUD to one session or follow the active one
• Keyboard: Enter send, Shift+Enter newline, Esc close (in-page)

Install

Requires a DSH web profile (0.1.0-rc.6+).

From a local checkout (bundle dir contains the built artifacts):

dsh plugin --profile web add "/path/to/hud-floating-bar"

Or from git (artifacts checked in, one-line install):

dsh plugin --profile web add "github:blktea814/hud-bar-for-dsh#main"

Then restart the web app. The HUD bar appears at the top-left of the page; the sidebar footer also gets a toggle button.

Usage

• Type a message, press Enter to send — the reply streams into the bar (and the main conversation, same session)
• Above the input: model / reasoning effort selectors; the primary button turns into 停止生成 while the agent runs
• Top row: status dot, session title, 外置 (PiP detach), pin/follow, close
• Second row: workspace / session selectors
• Drag the header to move, drag the bottom-right corner to resize
• Esc or Ctrl+Shift+H closes the in-page bar

Package layout

The Node half serves five same-origin endpoints:

Notes

• PiP detach requires Chrome/Edge 116+ (documentPictureInPicture); Safari/Firefox fall back to the in-page bar.
• Model switches take effect on the next agent step and are also saved as the default selection.
• Permission approvals are handled by the official main-UI approval card; the HUD only notifies you when one is pending.
