dsh-traffic-light

When chatting in the DeepSeek Harness Web UI, whether your session is idle and ready, actively generating, or has quietly hit an error is often buried in a line of microtext or a log entry. dsh-traffic-light turns that into a single red/yellow/green traffic light docked right below the input box: green means ready to send, yellow means the assistant is thinking or calling tools, red means the last request errored or was interrupted. Priority is strictly red > yellow > green, so the color you see is always the most urgent state right now.

Clicking the light opens a compact detail panel with a status explanation, error text and troubleshooting hints when something went wrong, and real-time throughput while generating. Every signal is read from the official session snapshot and projection fields — no polling, no guessing, no network requests. The plugin is a single self-contained file: CSS is injected inline, there is no build step and no external dependency, and it degrades gracefully if framework hooks are missing without breaking the composer.

Built for developers who use the DeepSeek Harness Web UI daily: at a glance you can tell who is waiting and who is running in shared sessions, spot an error without digging through logs, and glance at throughput to see if generation is stalling. It ships with Chinese and English i18n, respects dark theme via design tokens, and honors prefers-reduced-motion. Just install and refresh — the light is there.
