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. A recent report on an effort to systematically find bugs in Python extensions written in C has followed that approach. 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.
