Visualizer plugin for DeepSeek Harness: the `visualizer` tool streams a self-contained HTML document into the chat as it is written, live-previewed by a sandboxed inline frame. One package ships both halves: the model-facing tool and the Web GUI preview card.
Trace DAG visualizer for the dsh web GUI: a conversation view tab that projects the official trajectory snapshot into a ReactFlow trace graph with dagre / d3-force layouts, hover highlighting, and a slide-out detail panel.
Live plugin-topology viewer for DeepSeek Harness: the wiring diagram of every mounted plugin, its runtime activity, a composer-side star map — and a composition workbench that edits the wiring on the graph itself (previewed, validated, backed up, reversible).
