What are Docker Sandboxes for AI coding agents?

They're microVMs isolating agents with full kernel separation, mounted project access, and proxied networks—stopping escapes cold.

How does mise ensure reproducibility?

Mise.toml pins exact tool versions (Python, Node, etc.) across machines and sandboxes—no version mismatches derailing agents.

Is sbx-toolkit free and easy to set up?

Yes, open-source wrapper; one setup script per machine, .sbx.toml per project, then sbx-start launches safely.
