ViteHub is still experimental. Expect bugs and breaking changes.
Boxes
Understand when application code uses a Box and why it does not attach to an Agent Definition.
Boxes prepare isolated or trusted process environments with explicit Home, checkout, environment, requirements, and state. Use @vite-hub/box directly when application code owns that process lifecycle.
Boxes do not attach to Agent Definitions. The built-in Codex and Claude Code Agent Drivers run through the local provider runtime with a temporary Workspace, so defineAgent({ box }) is intentionally unsupported.
Use sandbox() to give a model-backed Agent an allowlisted executable tool, or a custom driver.run when application code must compose Box execution with an Agent Invocation.
