Description
This workflow acts as a System Prompt Optimizer Agent.
You send it a draft prompt or goal, and it returns:
A rewritten optimized system prompt that is clear, specific, and actionable.
A recommendation for the best OpenAI model to use based on reasoning needs, complexity, and latency/cost tradeoffs.
The workflow uses memory for context, so you can iteratively refine prompts.
