Historically, automated bug-finding tools have a bad habit of producing high-noise findings (and now worse: convincing AI slop) that just wastes maintainer time.
I built `cext-review-toolkit` using multiple specialized agents to find bugs, and I try to reproduce every finding from pure Python before reporting it.
Human review + pure-Python reproducers act as a necessary filter against false positives.

The results so far? Fixes merged in 14 projects! Massive shoutout to the maintainers of simplejson, Cython, memray, h5py, greenlet, bottleneck, guppy3, bitarray, igraph, APSW, Pillow, regex, and many others! The feedback they gave me, especially when pointing out my tool's false positives, was invaluable for making the scanners better. It's been incredibly rewarding to see the tools find interesting bugs and watch the community merge the fixes so quickly. #Python #CPython
