DSH Branch Visualizer: Transform DeepSeek Harness Session Branches into Actionable Tree Diagrams

dsh-branch-visualizer is a DeepSeek Harness plugin developed by 111222cjyq and licensed under the MIT License, designed to address the difficulty of visualizing branch structures in multi-session and sub-agent relationships. By reading sessions, parent sessions, and sub-agent relationships within the same workspace, the plugin automatically generates an interactive tree layout, supporting node dragging, zooming, panning, and auto-layout. Core features include double-clicking a node to quickly jump to a session, distinguishing between running/idle/cold statuses, renaming active sessions, and archiving cold sessions. The archive view supports toggling the display of history and connects the nearest visible ancestors of hidden nodes with double-dashed lines. In terms of performance, the plugin employs techniques such as snapshot TTL/LRU, request merging, and concurrency limits to optimize loading efficiency, and provides...
