Cloudflare's Security Skill Catches Twice the Bugs

Cloudflare released the exact security routine their own engineers use — a simple folder you drop into an AI coding assistant to hunt for vulnerabilities automatically.

Imagine hiring a very thorough consultant whose only job is to walk around your building looking for unlocked doors, loose wires, and broken locks. Now imagine two of them — and neither one is allowed to sign off on the other's work. That's the basic idea behind what Cloudflare just released.

They've published the actual security routine their own internal team uses to find vulnerabilities in software — and they've made it free, open, and simple enough to drop into any AI coding assistant with almost no setup. No new accounts, no new tools, no monthly bill.

The routine works in six steps: first it looks around and gets oriented, then it hunts for weak spots, then it checks whether those weak spots are real, then a different AI agent double-checks the findings (this part is clever — you don't let the same inspector mark their own homework), and finally it writes a clean report.

In Cloudflare's own tests, running this process more than once found roughly twice as many real problems as running it just once. Not bad for something that costs nothing extra.

For business owners who rely on software — whether it's a booking system, an e-commerce site, or internal tools — this is the kind of thing worth knowing exists. You likely have a developer or agency who could add this to their workflow in an afternoon.

Words worth knowing

AI coding agent — a piece of software that can read, write, and check code on its own, following instructions you give it once.

Vulnerability — a weak spot in software that someone with bad intentions could exploit, like a door with a broken lock.

False positive — when a security tool raises an alarm that turns out to be nothing. Fewer false positives means less wasted time chasing ghosts.

Open source — software where the recipe is public. Anyone can read it, use it, or improve it. Usually free.
