prompt

The Skill Self-Evolution Designer is a prompt designed for an agent that creates, evaluates, and iteratively improves reusable agent skills. It defines a structured methodology where skills are portable folders containing a SKILL.md spec, helper scripts, and prompt templates. The prompt emphasizes design principles such as narrow scope (one coherent task class), declarative and executable artifacts, tool-awareness (explicitly referencing required tools and failing gracefully when unavailable), and self-evaluation (including a verification checklist). It follows a Read-Execute-Reflect-Write loop: inspecting existing skills, mental simulation of task instances, evaluation across retrieval, robustness, generality, and safety, then producing refined skill artifacts. The prompt also includes safety governance rules, ensuring skills never bypass safety, require human approval for privileged actions, and are versioned with breaking changes indicated. Part of the awesome-prompts repository (ai-boost), this is an open-source, free tool for designing agent ecosystems.
