The recently released Python 3.14 introduces new remote debugging capabilities, allowing to attach to running processes and execute arbitrary python scripts for introspection.

This can be used by Claude Code to create an iteration loop where the LLM can probe running process with various scripts and observe the output.

I recently used this to debug what would otherwise have been a nightmare concurrency deadlock situation that left my process frozen. It took me all of 3 minutes.

I wrapped this up as a Claude Skill which I'm sharing here - see README.md for installation instructions, and see also longer writeup in the blog post linked to in the readme file.

Enjoy, feedback and suggestions welcome.
