Tool to configure and execute a multi-step LLM process?

I'm looking for a tool that allows a prompt-based architecture similar to a controller running through a list of tasks.

For example, if I ask it to make a guide on how to [insert learnable topic], the controller follows a list of steps: identify learning points, make a syllabus, prepare chapters, then generate each chapter. The controller AI prompts another AI thread to work on bouts of 1000 words and then compiles the responses for the final output.

I know groups are already doing stuff like this by coding it directly, but is there a packaged tool that behaves this way out of the box?
