Template notes

This workflow acts as a System Prompt Optimizer Agent. You send it a draft prompt or goal, and it returns: 1. A rewritten optimized system prompt that is clear, specific, and actionable. 2. 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.
