📄 Description

Overview

We recently worked on a backend refactor for deepagents that adds support for multimodal file types.

JS

The JS implementation for the refactor was done via a BackendProtocolV2 interface. For sandbox backends we added a SandboxBackendProtocolV2. The refactor is backwards compatible allowing users to continue using legacy file data as well as backends implementing BackendProtocolV1 via a backend protocol adapter implemented internally.

Python

Updated existing BackendProtocol to use new structured types and added new simplified backend protocol methods.
