About This Skill

Production prompts grow by accretion — every failure gets another appended rule until the prompt is two thousand words of contradictions that the model navigates unpredictably. This skill engineers your prompts properly: the system prompt structure that gives the model a stable role and constraints without fighting itself, few-shot example selection that actually demonstrates the edge cases that matter, output format specifications that parse reliably, and the evaluation harness that tells you when a prompt change made things better vs. just different. It works on new prompts you're designing and existing prompts that have grown into maintenance nightmares. Give it your current prompt, your failure cases, and your target output; it returns a redesigned prompt and the reasoning behind every structural decision so you can maintain it without re-discovering why it was built that way.
