I've been having some issues recently where my squad assistant transfer don't work smoothly. I've tried a mix of explicit transfer function calling (in the system prompt) to just natural language prompting with the appropriate desitnation name, but am not sure what the most solid/recommended approach is, and couldn't find any clear instructions in the API docs. What is the recommended approach to ensure transfers are consistently solid? This is between permanent assistants in a squad that are being given assistant overrides via API calls

Use the transferCall tool with defined assistantDestinations in your configuration instead of relying solely on prompts.
