What problem does it solve? Drafting effective prompts is hard: instructions are often vague, structure is missing, and advanced techniques get over- or under-applied. This Skill diagnoses a prompt draft or a stated goal, fixes only what is lacking, and verifies the result against a checklist. ## Core Features & Use Cases - Diagnosis-driven refinement: Evaluates structure (Instruction, Context, Input Data, Output Indicator), technique fit, and wording, then applies targeted fixes instead of rewriting everything. - Technique catalog with escalation: Guides selection from zero-shot to few-shot, CoT, self-consistency, and prompt chaining, with special handling for reasoning models like o1/o3 where manual CoT should be removed. - Checklist verification: Validates the final prompt against structure, expression, technique, and safety criteria (e.g., no leaked API keys, fallback responses for factual tasks). - Use Case: You have a rough system prompt for a classification task. The Skill detects missing output format and unbalanced few-shot labels, restructures it with delimiters, and explains each change. ## Quick Start Ask the assistant to refine your draft prompt or create a new prompt for a specific task, for example by saying "refine this prompt for classifying customer feedback into positive, negative, and neutral categories".
