thimble: open-source Claude Code plugin makes agent outputs explainable in your terminal

AlexTamkin · x · 2026-11-11

@mjoerke (safety-research) released thimble, an open-source (Apache-2.0) Claude Code plugin for understanding what agents did. It gives Claude tools to cite, visualize and label your data, with an interface to verify Claude's work faster — "Claude Code is for building, thimble is for understanding." Shortcuts: v to visualize the last answer as an interactive card, s to simplify it, c to cite. Research prototype, not an official Anthropic product.
