Cloudflare's AI Security Auditor Skill, Explained

Описание: Cloudflare open-sourced the skill that seeded its AI vulnerability-hunting harness. It turns your coding agent into a security auditor, with one strict rule: the agent that checks a finding is never the agent that found it.

In this video:
the problem: AI bug hunters that grade their own homework
what an agent "skill" actually is
the six phases: recon, coverage-led hunting, candidate validation, structured output, independent record verification, reporting
the three verdicts: confirmed, needs_validation, rejected
why it needs a sandbox before it runs any code
use cases, and how you'd install and use it (README walkthrough, not run)
the honest limits
