[$] Using LLMs to find Python C-extension bugs

The open-source world is currently awash in reports of LLM-discovered bugs and vulnerabilities, which makes for a lot more work for maintainers, but many of the current crop are being reported responsibly with an eye toward minimizing that impact.

Hobbyist Daniel Diniz used Claude Code to find more than 500 bugs of various sorts across nearly a million lines of code in 44 extensions; he has been working with maintainers to get fixes upstream and his methodology serves as a great example of how to keep the human in the loop—and the maintainers out of burnout—when employing LLMs.
