## Summary A split-up PR of #1763 , stacked on top of a tools refactor #1858 to make the change clearer. From the previous summary: > Let's try something new: tell the model about the sandbox, and let it decide when it will need to break the sandbox. Some local testing suggests that it works pretty well with zero iteration on the prompt! ## Testing - [x] Added unit tests - [x] Tested locally and it appears to work smoothly!

This crate is designed for utilities that need to be shared across other crates in the workspace, but should not go in core.
For narrow utility features, the pattern is to add introduce a new feature under [features] in Cargo.toml and then gate it with #[cfg] in lib.rs, as appropriate.
