No, it doesn't, I only run agents in a dedicated development environment (somewhat sandboxed in the file system) but that's how I've used them since the beginning, I don't want it to be accessing my file system as a whole, I only need it to look at code.

Don't think a web-based dev environment would be enough for my use case, I point agents to look into example code from other projects in that environment to use as as bootstraps for other tools.
