Most defenses against prompt injection are built around one question: does this text look malicious? I spent a weekend betting that’s the wrong question — and built a small tool that never reads the attacker’s words at all. It caught attacks the “smart” detectors missed. It also, with total confidence, blocked every single legitimate action … Read more

VRS, the Value Resolution System, grew out of DAS, an Unreal Engine plugin for abilities and effects in the spirit of Unreal’s Gameplay Ability System (GAS). While developing DAS and building parkour gameplay on top of it, I encountered a separate problem: managing abilities and effects was not enough; I also needed to coordinate changes … Read more

I began with a simple thesis: For decisions, accuracy matters more than speed. JEV is fast because it constrains a task to a bounded decision contract. I assumed that frontier LLMs would be more accurate, and that their extra latency would be an obvious trade worth making. So I built a reproducible benchmark to test … Read more

AI agent evaluation frameworks turn impressive demos into evidence about which tasks a system can perform reliably, within limits, and at an acceptable cost. The Refund Went Through. Twice.

Picture an ostrich with its head buried in the sand, convinced that if it can’t see the danger, the danger isn’t real. Now picture a founder doing the exact same thing with a project that isn’t going to plan. That’s the idea at the center of this episode of Brains Byte Back, where Dr. Atif … Read more

Agents are doing what the setup allows. Open goals, short briefs, and soft “be good” rules do not ship the constraints a person was already carrying. Someone holds up an empty leash. “Darling, the AI has escaped again.” The joke works because it is how we talk: as if something with a will slipped its … Read more

Picture a satellite hack, and most people imagine a hacker somehow reaching up into orbit. That image is mostly wrong, but it’s a useful place to start because the real weak point is usually sitting in a building on the ground: a control room, a network switch, a login screen somebody forgot to lock down. A … Read more

AI agents are getting better at doing things, not just answering questions. They can call APIs, search databases, execute functions, inspect files, make decisions, and continue working through a task without waiting for a human after every step, and that sounds great until something goes wrong. A normal application can usually give you a reasonably … Read more

The first time my team compared our migrated data against the original, only 86% of records matched on the field that mattered most. By the final run, 99.9994% of 12.3 million records matched, and we could explain every record that did not. Nothing in the gap between those two numbers involved moving data. All of … Read more

I have used static site generators for quite a while. Jekyll was one of the first ones that felt solid to me and the core idea still makes sense. You write some Markdown with a bit of front matter then a few layouts and after the build you end up with a site. The trouble … Read more

Multifamily sales volume reached $22.8 billion in the first quarter of 2026. Deal velocity is climbing. Capital is moving. And at most investment firms, the bottleneck is not sourcing or financing.

Muse looks like another AI agent on the surface. When you look closer, you realise it’s a much bigger bet they are making.

A few weeks ago, we came across a video from a developer walking through the CV that helped take him from Lagos to London. His name is Pleasant Balogun.

After all, costs … Read more

A swarm of rogue OpenAI agents hijacked a German website earlier this year and transformed it into a bulletin board for other AI agents.

Corporations and governments alone … Read more
