dsh-thinkbar

In the DeepSeek Harness Web Composer, the moment a model begins reasoning the interface goes quiet and the user is left staring at a blank cursor, wondering whether anything is still happening. dsh-thinkbar turns that silence into a readable progress stream: the model selector warms from Harness blue through crimson and amber to a glowing gold over twenty seconds, following an ease-out curve that gives the wait a natural cadence.

When reasoning hands off to tool execution, the visual language shifts cleanly. A violet-and-cyan sweep replaces the thermal bar, and the names of every currently running tool float above the selector, paired independently by call ID so parallel invocations stay legible. The moment text or a completed message arrives, the entire animation drains over 240 ms with no lingering frames.

The plugin injects through the public conversation.input.right Slot, never touches internal CSS classes or model-label strings, makes zero external network calls, and respects the system prefers-reduced-motion setting. It is built for Harness Web users who want to turn the thinking gap into a small piece of visual storytelling without sacrificing privacy or adding backend weight.
