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.

Arsenal-NG gives penetration testers instant fuzzy search across 2,800+ pentest commands in a terminal UI written in Go. Here's why it's worth adding to your toolkit — and what security leaders need to understand about the tools their red teams use.
