What problem does it solve? Writing effective system prompts from scratch is error-prone: instructions end up ambiguous, guardrails get forgotten, and output formats are left unspecified. This Skill provides a proven structure and workflow so every prompt you write is complete, unambiguous, and testable. ## Core Features & Use Cases - 9-Element Structure: Covers task context, tone, rules, few-shot examples, input data, immediate task, scratchpad reasoning, output formatting, and prefill. - 6-Level Emphasis Scale: Calibrate rule strength from "Please do X" up to "CRITICAL - ZERO TOLERANCE". - 8-Step Creation Workflow: Move from objective definition through mental edge-case testing to iteration. - Specialized References: Load RAG patterns (chunking, citation injection, hallucination prevention) or multimodal prompting patterns (screenshot-to-code, diagram understanding) on demand. - Use Case: You need a system prompt for a customer-support classifier. Follow the workflow, apply the 9-element template, add few-shot examples for edge cases, and set critical rules at the right emphasis level. ## Quick Start Write a system prompt for a code review assistant using the 9-element structure with two few-shot examples and critical rules for security issues.
