Introducing deepsec: The security harness for finding vulnerabilities in your codebase

Introducing deepsec: The security harness for finding vulnerabilities in your codebase

Today we’re open sourcing deepsec: a security harness powered by coding agents. It runs on your own infrastructure and surfaces hard-to-find issues in large codebases. You can run deepsec on your laptop without setting up a cloud service for privileged source code access. For inference, you can use your existing Claude or Codex subscription without any additional setup.

How to prompt v0

Working with v0 is like working with a highly skilled teammate who can build anything you need. v0 is more than just a tool, it’s your building partner. And like with any great collaborator, the quality of what you get depends on how clearly you communicate.

Protecting against token theft
Jun 4, 2026

Protecting against token theft

HTTP requests are inexpensive. Vercel charges ~$2/million, a fraction of a cent per call. But a single prompt to an agent on a frontier model can cost $2, making AI a million times more expensive, and inference theft one of the highest-margin businesses an attacker can run. We have seen this type of attack on our own APIs.

Working alongside Sakib at Cozmiq showed me what it actually means to ship. He doesn't just write code — he thinks in systems. The AI automation workflows he architected became core infrastructure we relied on every single day. Rare to find someone who moves that fast without compromising quality.

Collaborating with Sakib on the Cozmiq stack was genuinely impressive. His code is clean, his architecture decisions are deliberate, and he ships fast without cutting corners. The kind of developer you want owning critical systems — reliable output, zero hand-holding required.
