the security product is now a skill file your agent runs. cloudflare open-sourced a six-phase audit skill that assigns independent checkers, adversarially disproves candidates, and labels every finding confirmed, needs_validation, or rejected instead of trusting the model's claim.
the agent output gets audited by other agents.
Context
Cloudflare's security-audit-skill repository, MIT licensed and created on 18 June 2026, describes a coding-agent skill with a six-phase pipeline: recon, hunting, validation, reporting, structured output and independent verification. In validation, separate agents try to disprove each finding, and fresh agents check every factual claim in the structured output against source. The repo says it seeded Cloudflare's vulnerability-discovery harness.
The six phases and the adversarial validation are first-party, read from the repository. The labels confirmed, needs_validation and rejected: the schema file read lists confirmed and rejected, and needs_validation was not found in the text read, so it is unverified. Repository creation on 18 June is not an open-source announcement date, and no dated announcement was read. The skill describes a method and is not a guarantee of finding or ruling out vulnerabilities, and the checking agents are the same kind of model. That the security product is now a skill file is the author's thesis.

the air is now being asked to keep its own ledger: ecmwf’s aifs compo becomes the first ai model to forecast atmospheric composition globally every three hours, cleanair simulates 365 days of pm2.5 over china in ten seconds, and a unified framework maps six pollutants at one kilometer across the whole country. the air now files its own composition report.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.

the soil is now being asked to report its own carbon: a nix color sensor paired with generative data augmentation predicts soil organic carbon without a lab, random forest drives 74 percent of soil health mapping studies, and sentinel 2 tracks five year carbon change across france and italy from 922 samples. the dirt now files its own carbon account.
