GoogleCloudPlatform/scion

About the project

Scion is a multi-agent orchestration platform that runs several isolated agents concurrently in containers, optionally giving each one its own workspace and credentials. It is used to coordinate coding and other research or operations tasks across local machines, remote virtual machines, and Kubernetes clusters. Catalogue add-ons provide workflows and controls for operating Scion.

This repository also configures its own agents. See what scion tells them →
