Detailed Description

A workflow that chains multiple prompts together.

This workflow decomposes a task into a sequence of steps, where each LLM call processes the output of the previous one. It can add programmatic checks between steps to ensure the process is on track.

Examples

prompt_chain_example.cpp, and simple_workflow.cpp.
