Sandbox Fleet gives an Agent provider-neutral tools for parallel or isolated compute. Daytona backs the capability today, but the model sees only Everruns logical Sandbox IDs. Provider resource IDs, credentials, and translation stay in the trusted control plane.

These are resource Sandboxes. They never replace the session’s primary Sandbox: ordinary shell and file tools continue to use the primary Sandbox configured by the Harness and Agent.

ToolPurpose
sandbox_createCreate a resource Sandbox and return its session-scoped logical ID
sandbox_execRun a command in an explicitly named Sandbox
sandbox_read_fileRead a file from an explicitly named Sandbox
sandbox_write_fileWrite a file in an explicitly named Sandbox
sandbox_listList the current session’s resource Sandboxes
sandbox_inspectInspect one resource Sandbox without exposing provider bindings
sandbox_checkpointCopy its workspace into durable session file storage
sandbox_manageStop or delete it

Every operation after creation requires sandbox_id. An ID from another session is rejected. Delete resource Sandboxes when the work is complete.

The older daytona capability remains available for existing Agents and provider-specific operations. New provider-neutral fleet workflows should use sandbox_fleet.
