Are there any best practices for implementing a composer agent?

I searched through a large amount of documentation and discussions about AI agent. As far as I know, streamText can currently call multiple tools (in parallel or in multiple rounds, but I am still unclear about the circumstances under which a multi-turn mechanism will occur.)

My requirement is to achieve an agent similar to cursor composer that can think in the first step, call tools, check results, and so on until completing a complex task without human intervention. I found the section about agent design in the document, but those are all predefined logic. https://sdk.vercel.ai/docs/foundations/agents#sequential-processing-chains

I would be very grateful if someone could tell me how to enable LLM to self-plan and execute processes.
