WHAT IT DOES

What cloud_sandbox_list does on CoWork OS

AI agents call cloud_sandbox_list to retrieve information from CoWork OS without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why cloud_sandbox_list is rated Low

This tool performs a read-only operation to enumerate active cloud sandboxes. It retrieves data with no side effects, mutations, or external operations triggered. The blast radius of misuse is minimal—an agent could gain visibility into existing sandboxes but cannot modify, delete, or execute operations within them.

From the tool's definition Tool name 'cloud_sandbox_list' and description 'List all active cloud sandboxes' indicate a query/listing operation that retrieves information without modifying state.

cloud_sandbox_list Allowed

cloud_sandbox_list is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
