Agentic Engineering Teams on Sunstone Atlas: What They Are Made Of
Thor Henning Hetland (Totto) & ExoCortex, our agentic rig of Claude and Fable. Drafted by Claude Fable 5.1. Oslo, October 2026.
TL;DR, and the business summary
What this is. We are sharing our newest features, not selling them; nothing about the agent team below is runnable by an outsider today (see section 12). Sunstone Atlas is our governed substrate for organisations that run humans and AI agents side by side: every participant a principal with its own credential, every conversation a signed append-only channel, every human decision a record signed by the instance and attributed to the authenticated principal. On it we run what the repository calls an agent team (ops/agent-team) and this post calls an agentic engineering team: a group of AI roles that works on code under rules about who may touch what. Ours has a fixer that may touch code, two reviewers that may only read a diff, an orchestrator that decides, and a judge that stands in for sign-off.
