A native macOS companion for Claude Code that lets you browse sessions, explore diffs, and re-run commands.
# Add to your Claude Code skills
git clone https://github.com/leonardocardoso/poirotPoirot was vibe-coded in a weekend. The entire app — architecture, parser, UI, tests — was built in a single creative burst with Claude Code as the co-pilot. What started as "I wonder if I can build a companion app for Claude Code... using Claude Code" turned into a real, usable tool.
Named after Hercule Poirot, Agatha Christie's legendary detective. Because every great investigation needs the right tools — and Poirot helps you investigate exactly what your AI assistant has been up to.
