概要
This skill provides comprehensive guidance and proven templates for designing high-performance system prompts for autonomous agents. It helps developers fine-tune agentic behavior—such as proactivity levels, tool-calling efficiency, and verbosity control—to ensure more reliable results in long-horizon reasoning and specialized tasks like research, document creation, or frontend generation. By utilizing XML-structured templates and explicit instruction principles, users can significantly reduce hallucinations and improve the success rate of complex subagent orchestrations.
