Mythos/Fable is out... Before the thought leaders start publish whitepapers, or hosting "CISO dinners" etc, I'll offer some boring/sobering advice: 1. Make sure you know where all your stuff is - ya even that 3rd party software that the person in accounting bought on a credit card in 2016.

Most security tools slow you down. Most fast tools ignore security. We wanted both. So we built Workcell. It started with a few co-conspirators asking: "How do we vibe code at yolo speed and not get owned?"

Coding agents are powerful. They’re also one bad boundary away from self-compromising your machine. I wanted the speed of “YOLO mode” without giving up isolation, so I built Workcell. With a lot of help from Codex, Claude, Gemini, and Rick, it’s now out: github.com/omkhar/workc...

A few years ago, when I was working at @openssf.org , we partnered with @darpa.mil on the AI Cyber Challenge. Yesterday's news from @anthropic.com about Mythos and Glasswing both highlight the opportunity that we saw, and the primary reason we were so focused on securing open source software.
