AgentAstra: A Spatialized Conversation and Trajectory Visualization Plugin for DeepSeek Harness

AgentAstra is an experimental client plugin for DeepSeek Harness designed to project the Agent execution process into a traversable spatial view, replacing the traditional linear message flow display. By leveraging three dimensions—semantic time, causal channels, and information hierarchy—the plugin intuitively visualizes key nodes and their causal triggers, such as user prompts, Agent replies, tool calls, sub-Agent delegation, file read/write operations, and external resource access. Core features include displaying conversation content as readable cards with support for keyboard navigation, timeline dragging, and node focus interactions; allowing precise file snapshots to be dragged directly into chat box drafts; binding the view to the current session to automatically release WebGL resources upon unloading; and providing a text fallback when WebGL is unavailable. Installation is performed by adding the plugin using the `dsh plugin` command.
