Instead of scanning more code, afaict what you seem to want is instead, scan on the same small area, and compare on how many FPs are found there. A common measure here is what % of the reported issues got labeled as security issues and fixed. I don't see Mythos publishing on relative FP rate, so dunno how to compare those. Maybe something substantively changed?

At the same time, I'm not sure that really changes anything because I don't see a reason to believe attacks are constrained by the quality of source code vulnerability finding tools, at least for the last 10-15 years after open source fuzzing tools got a lot better, popular, and industrialized.

This might sound like a grumpy reply, but as someone on both sides here, it's easy to maintain two positions:

1. This stuff is great, and doing code reviews has been one of my favorite claude code use cases for a year now, including security review. It is both easier to use than traditional tools, and opens up higher-level analysis too.

2. Finding bugs in source code was sufficiently cheap already for attackers. They don't need the ease of use or high-level thing in practice, there's enough tooling out there that makes enough of these. Likewise, groups have already industrialized.

There's an element of vuln-pocalypse that may be coming with the ease of use going further than already happening with existing out-of-the-box blackbox & source code scanning tools . That's not really what I worry about though.

Scarier to me, instead, is what this does to today's reliance on human response. AI rapidly industrializes what how attackers escalate access and wedge in once they're in. Even without AI, that's been getting faster and more comprehensive, and with AI, the higher-level orchestration can get much more aggressive for much less capable people. So the steady stream of existing vulns & takeovers into much more industrialized escalations is what worries me more. As coordination keeps moving into machine speed, the current reliance on human response is becoming less and less of an option.
