“ We take a stance with the sandboxing that hurts us in terms of general adoption. However, we do not want to promote something that could be unsafe by default. As a dev, you can always go into your configuration and disable these settings if you want.” Thibault Sottiaux Head of Codex · Leader , OpenAI

“ How do we dare to do this in a bank? Well, we have the rules built in, and he doesn't have access to the customer data … And then he really tried to get the customer data. He tried to look at the … infrastructure and construct the connection string and all that, but we don't have secrets in our connection strings … managed identity to connect to the database, and his service principal … not have access to the database, so he couldn't get any data.” Hallstein Brøtan Senior consultant, Novanet; developer on Nordic Corporate Bank's system · Practitioner , Nordic Corporate Bank

“ There is structure: doctrine and policy, human gates, and just fourteen mechanical “fences” (programmatic denials). But my agents are first-class colleagues. They work under my own identity, signing their own names to the work, and they can see the whole system and act independently. It is YOLO mode scaled up to the size of a small company.” Steve Yegge Independent; builds and runs Wheelhouse, a solo multi-agent software factory (2026) · Executive , Steve Yegge (independent)

“ Again, we are a bank. We live in a regulated environment. So, we want to make sure that the non-determinism from the agents is controlled. But at the same time, we want to have an environment where we can let it run loose and develop.” Felippe Felisola Caso Monzo (conference affiliation, 2026) · Practitioner , Monzo
Context. Felisola Caso is explaining why Monzo's agents run in a sandbox in an isolated namespace, separate from production infrastructure.

“ The isolation philosophy comes from two things, right? First, we obviously want to reduce the blast radius if a agent goes haywire. That's mainly provided by running these in isolated sandboxes. That can obviously be in Docker or in containers, that can also be on separate EC2 instances. However, you like to manage your isolation.” Shardul Vaidya Solutions Architect, Data and AI, AWS · Practitioner , Amazon
Context. Vaidya, an AWS solutions architect, is describing and demoing a dark factory (software built and merged by agents) that he built himself, which he calls "my factory"; it is not presented as an AWS product.

“ We took inspiration from Terraform: agent definitions should live in version control and move through the same review and deployment process as the rest of the product. An agent’s instructions, model, tools, and environment are declared in code, and our deployment pipeline registers changes with Laminar.” Sam Kronick Author of Ramp's "Building Laminar" engineering blog post · Practitioner , Ramp
