dsh-plugin-prune

As your plugin list grows past twenty or thirty, it gets hard to tell which ones are actually doing work and which have been quietly idle since the day you installed them. dsh-plugin-prune exists to answer that question with data rather than gut feeling. It is a pure local observer: it registers no model tools, touches no business state, and simply listens to every tools/execute and tools/result event, tallying call counts, error rates, average latency, distinct sessions, and rendered output size across a rolling 90-day window for each tool and skill.

Once enough data has accumulated, a new Plugin Health tab under Settings, Plugins gives you a plugin overview table cross-referenced with the shipped inventory, plus a per-tool and per-skill detail view. Every row carries a machine-generated suggestion — never called, high error rate, marked useless, or active and reliable — and lets you assign your own Useful, Neutral, or Useless rating in one click. Statistics persist to a local JSON file, so counters survive restarts and accumulate across sessions.

It is built for DeepSeek Harness users who have outgrown the install-and-forget habit and want an honest, objective signal before uninstalling. Everything stays on your machine; nothing is sent anywhere.
