Anthropic shipped a security scanner for Claude Code. It reads your codebase, hunts vulnerabilities, and writes the patches. I pointed it at
the SaaS I'm actually building, with real users on it.
Full install including the config switch nobody mentions, a real scan on production code, and what it does to your usage limits.
I run a full security and pen-test pass before anything of mine goes near a server, that runbook, and the rest of them, live in ShipDojo. Free while I'm building it: https://shipdojo.com/

⚠️Scan your own code only
Everything in this video is run against my own application, on infrastructure I own. Only scan and test code you own or have written permission to test. Finding a vulnerability in someone else's app doesn't give you the right to touch it, report it to them instead. Unauthorised scanning or exploitation is illegal in most countries, whatever the tooling.
