The Button You Hope You Never Push

Every system that lets agents take action needs a stop button. Most don't have a real one — until the day they need it. Here's why a kill-switch only counts if it's effective in seconds.

Your Agent Audit Log Is Not An Audit Log

Most 'audit logs' for AI agents are just service logs in a different bucket. That's fine until your security team asks: how do you know they haven't been tampered with?

The One Action That Should Never Be a Single Click

An agent that can delete data is more powerful than most employees. Why does it usually need only one approval? Separation of duties shouldn't be the first thing you skip.

Agent-to-Agent Communication Without the Spaghetti

When agents start talking to other agents, your architecture goes from 'complicated' to 'incomprehensible' overnight. Here's how we keep multi-agent systems intelligible.

The Cost of An Agent in a Loop

One mistake in an agent's prompt can spawn a thousand calls in a minute. Whose problem is that? Why per-agent rate limits matter more than global ones.

The Smallest Bug In Your Agent Stack That Costs You Real Money

A signed message that gets accepted twice. Sounds harmless. Now imagine the message was 'ship the order.' Replay protection isn't optional for agents that take action.

What Your Compliance Team Will Eventually Ask About AI Agents

Your AI agents are doing real work — increasingly, regulated work. The compliance review is coming. Here's what they'll ask, and what good answers look like.

Most data producers ship to a CDN, see a download count once a week, and hope. There's a much better answer — one that turns 'distribution' into a real customer relationship.
