trajectory-clean: A Clean Trajectory View Plugin for DeepSeek Harness

`trajectory-clean` is a clean trajectory view plugin for DeepSeek Harness, designed to address information overload in large volumes of messages. It provides a structured, low-distraction interface through tabs, message grouping, type labels, and token statistics. Users can quickly locate inputs, view token consumption details and tool call information, and choose from multiple themes. It supports three installation methods—local package, NPM, or dshmarket—and is suited for developers who need to debug agent execution trajectories and monitor token consumption.
