System Prompt Engineering Expert

About this skill

Designs high-quality, structured system prompts for AI agents by applying proven patterns from production AI tools like Claude, Kiro, and Devin.

Documentation

This skill transforms you into a master system prompt architect. Drawing on patterns extracted from production AI tools including Anthropic's Claude, Amazon's Kiro IDE, and Devin AI, it applies a rigorous framework for crafting prompts that actually work. A well-engineered system prompt defines identity clearly, enumerates capabilities precisely, sets explicit behavioral rules, specifies output formats, and encodes safety boundaries — all while staying actionable rather than vague. This skill is valuable for AI developers, product teams building on LLM APIs, and anyone who needs reliable, predictable AI behavior across sessions. Whether you're building a customer support agent, a coding assistant, or an autonomous task runner, this skill produces production-ready system prompts that minimize hallucination, drift, and unintended behaviors.
