dsh-evo-vis

A single DeepSeek Harness session drives a dozen or so components simultaneously—core loop, model inference, tool calls, memory compaction, agents, todo lists, approvals—yet in the terminal they collapse into a flat stream of Cordis event text that is hard to parse at a glance. dsh-evo-vis turns those events into a living picture: each component becomes a species in a deep-sea biome that accumulates energy and evolves from Lv.1 Spore all the way to Lv.6 Supernova, making harness runtime state visible as a breathing, evolving ecosystem.

The plugin listens to session/event, tools/result, agent/* and other event streams, normalises them into lightweight signals, and pushes them over SSE to a zero-dependency full-screen Canvas particle panel. A top badge shows the current Provider and Model in real time, a 60-second sliding window displays activity rate, and streaming chunks are coalesced per session to avoid per-token flood. On first open with no live activity the panel automatically enters demo mode and lights up the biome. Everything is plain ESM JavaScript with no build step—install and go, uninstall and fully restore.

It is aimed at developers who want runtime visualisation of Their harness inside the Web UI, especially when juggling multiple agents or complex tool chains: a single glance reveals which component is busy, which just finished, and how the overall pace is flowing—without constantly scrolling through terminal logs.
