I’m Alex Herrero — a security-minded engineering leader. By day I lead engineering for AI-driven threat detection at Google Cloud. Off the clock I build the tools this site is about: Agent M, a harness that gives coding agents durable memory and a phase-gated workflow, and Crickets, the safety and verification primitives that ride on top — kill-switches, fresh-context evaluators, guardrails.
This blog is where I write about the experiments behind those tools: what I’m trying to make AI agents reliable, safe, and genuinely useful, and what I learn running them against real work.
