## Summary

Matthew Jörke says he built thimble, an open-source Claude Code plugin that helps users understand what agents did. It adds explainers and interactive visualizations in the terminal, and the post links to its GitHub repository.

## Why it matters

The author built the plugin, so the post explains a tool created for reviewing what Claude Code agents did in the terminal.
