For some very basic level protection use devcontainers and install the agent into that....
A better approach is to use the Docker Sandboxes feature. Locks things way down so that the agent only has access to the files you give it and you can lock down its network access too. Also does things like keep any credentials outside of the container (microvm actually).
The site was actually built as an experiment on "spec first" coding with AI agents... in this case using Codex CLI. Underlying tech is Typescript, React, Zustard (for state), Bootstrap (for layout/components) and Konva JS (for 2D canvas) and vite for building/bundling. Deployed to AWS S3 bucket fronted by AWS cloud front using Github actions.
Yeah, foam core is easy to work with but a bit thick. The tool does let you set the thickness in the project properties so you may be have some luck setting it to be thinner.
It should hopefully work better on a phone/tablet now. I'm planning on adding a video soo showing how to use the app and what it does... but you can check out https://www.reddit.com/r/boxinsertdesigner/ for examples
Basically you want to become a "Force Multiplier" for your team, thinking a few steps ahead, seeing the big picture, guiding everyone past upcoming road blocks, you need to be able to mentor/help out when it its the fan. And of course you still need to code ;)
