Agentic Ai

A deep dive into the Domain-to-Domain (D2D) agentic protocol — the coordinator, worker, and killer node model that lets autonomous AI agents collaborate across security domains without human-in-the-loop bottlenecks.

What do the actual files look like inside a production D2D worker node? We break down the manifest, system prompt, and tool definitions that make each agent composable, safe, and auditable.

The coordinator node is the brain of a D2D agentic system. Here's how it decomposes missions, handles partial failures, and knows when to escalate rather than guess.

Lessons from wiring up a D2D multi-agent system to a production SOC: the PagerDuty integration, the human review queue, what broke, and what surprised us.
