deepseek-harness-picture-in-picture

When you are juggling docs, terminals, or design tools alongside Harness and keep losing focus every time you switch tabs to check a streaming reply, hop sessions, or drop a quick correction, the full Web GUI in a dedicated tab is a constant context switch. This plugin extracts the core chat interaction into a compact 420 by 660 Picture-in-Picture window that floats above every other window on screen, so you can follow replies, approve tool calls, or queue a new prompt without ever leaving your current workspace.

On Chromium-family browsers it uses the native Document Picture-in-Picture API for true always-on-top placement; other browsers fall back to an in-page floating panel automatically. Inside the mini window you get a session switcher with live working, waiting, and completed badges, a compact Markdown transcript covering streaming reasoning, tool activity, and history loading, inline approval and plan-review panels, image-attachment submission, and real-time token throughput and cache-hit statistics. Switching a chat in the mini window keeps the main Harness window in sync, and replies go through the public queue API with options to edit, remove, or send-now a queued message while the agent is still working.

It is built for developers running Harness in a Chromium browser who keep productivity tools side by side and want to glance at AI reasoning progress, approve a tool call, or nudge the conversation without breaking flow. No extra services, environment variables, or separate server are required -- install the plugin, refresh the GUI, and a chat-bubble button appears in the bottom-right corner.
