概要
The System Prompt Writer skill empowers developers to craft effective, high-signal instructions for AI agents by applying Anthropic’s 'Effective Context Engineering' principles. It helps users achieve the 'Goldilocks zone' of prompt altitude—ensuring instructions are neither too vague nor overly rigid—to maximize agent performance. The skill provides a standardized hybrid structure using Markdown and XML, and includes critical technical guidance on template variable escaping to prevent execution errors in Python-based agent systems.
