VulnHunter: an AI agent that hunts code flaws like an attacker would

VulnHunter is an open-source AI security tool released by Capital One that analyzes source code directly to find vulnerabilities. It takes an attacker-first approach, proactively probing code the way an attacker would rather than just reviewing it after the fact, aiming to surface risky spots before a human even looks. It's published on GitHub in a form meant to be applied straight to a code repository.
