// This sample shows how to use HyperlightCodeActProvider with provider-owned
// tools (exposed inside the sandbox via `call_tool(...)`). The model can
// orchestrate those tools in a single Python block, reducing round-trips. A
// sensitive tool (`send_email`) is additionally wrapped in
// ApprovalRequiredAIFunction so any code that reaches it requires user approval
// for the entire execute_code invocation.
