IMHO these type of projects are not tools per-se but methodologies. I think this is a better framing since that's exactly what they are - a bunch of markdown files that describe in general terms how to perform an assessment aligned to some principles.

Btw, these type of methodologies are used all the time. Practically every security consultancy has them so adding them to an LLM makes a lot of sense.

All these security/vulnerability scanning harnesses look more or less the same. Not sure what’s the point of bragging or publishing about them anymore, there’s no moat

If there is a pentester here who uses mitmproxy, the security skills below (distilled from 4000 h1 disclosures) might help -https://github.com/instavm/security-skills

this is just a side project though for me

Wasn't Capital One founded on the premise of massive-scale market and product experimentation? Makes sense that they would design tools that match that approach.

Why does this feel like an exec trying to justify token spend?

Has anyone actually had success with this? I applied for my company several weeks ago, and never heard back.

This is a sad. Makes me want to move my bank accounts.
