Claude Code plugin reveals agents redo 11% of work; 'true' ran 59 times across 8,467 calls

A developer open-sourced Groundhog, a read-only Claude Code plugin that analyzes locally saved session JSONL files to quantify how much redundant work your agent does.
Across the author's 369 sessions and 8,467 tool calls:
- 11% of calls redid work already done
- One file was re-touched 84 times
- The do-nothing true command ran 59 times
- Most telling: when the agent looked at the same thing twice, 74% of the time the world had already changed between looks — implying caching/memory designs must account for state staleness
The plugin runs fully locally, uploads nothing, and edits nothing. Install via /plugin marketplace add fraqtl-ai/groundhog, then run /groundhog:stats. The author notes limited value for solo devs but real utility for agent fleets.
