# 创建自定义 Skill

Skill 的创建很简单 - 只需一个包含 SKILL.md 文件的文件夹。SKILL.md 包含 YAML frontmatter 和 Markdown 指令：

```markdown

---

name: my-skill-name

description: 清晰描述这个 skill 做什么，以及什么时候应该使用它

---

# My Skill Name

[在这里添加 Claude 执行此 skill 时需要遵循的指令]

```

Frontmatter 只需要两个字段：

name - skill 的唯一标识符（小写，用连字符分隔）
description - 完整描述 skill 的功能和使用场景

更多详情请使用 /testany-llm:skill-creator，或参考 [skill-authoring.md](./plugins/testany-llm/skills/skill-creator/references/skill-authoring.md)。
