About Skills

关于 Skill

Skills are modular, self-contained packages that extend an AI's capabilities by providing specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific domains or tasks—they transform AIs from general-purpose agents into specialized agents equipped with procedural knowledge that no model can fully possess.
Skill是模块化、独立的包，可通过提供专业知识、工作流和工具来扩展AI的能力。可以将它们视为特定领域或任务的“入门指南”——它们将通用型AI Agent转变为具备程序知识的专业Agent，而这些知识是任何模型都无法完全拥有的。

Anatomy of a Skill

Skill 的结构

Every skill consists of a required SKILL.md file and optional bundled resources:
dirtree
skill-name/
├── SKILL.md (required)
│   ├── YAML frontmatter metadata (required)
│   │   ├── name: (required)
│   │   └── description: (required)
│   └── Markdown instructions (required)
├── scripts/          - Executable code (Python/Bash/etc.) (optional)
├── references/       - Documentation intended to be loaded into context as needed (optional)
└── assets/           - Files used in output (templates, icons, fonts, etc.) (optional)
每个Skill都包含一个必填的SKILL.md文件和可选的捆绑资源：
dirtree
skill-name/
├── SKILL.md (必填)
│   ├── YAML 前置元数据 (必填)
│   │   ├── name: (必填)
│   │   └── description: (必填)
│   └── Markdown 操作说明 (必填)
├── scripts/          - 可执行代码（Python/Bash等）(可选)
├── references/       - 按需加载到上下文的文档 (可选)
└── assets/           - 输出中使用的文件 (可选)

SKILL.md (required)

SKILL.md (必填)

Metadata Quality: The 
name
and 
description
in YAML frontmatter determine when an AI will use the skill. Be specific about what the skill does and when to use it. Use the third-person (e.g. "This skill should be used when..." instead of "Use this skill when...").
元数据质量：YAML前置元数据中的
name
和
description
决定了AI何时会使用该Skill。请明确说明Skill的功能及适用场景。使用第三人称表述（例如：“当...时应使用本Skill”，而非“当...时使用本Skill”）。

Bundled Resources (optional)

捆绑资源 (可选)

Scripts (
scripts/
)
Scripts（
scripts/
）
Executable code (Python/Bash/etc.) for tasks that require deterministic reliability or are repeatedly rewritten.
  • When to include: When the same code is being rewritten repeatedly or deterministic reliability is needed
  • Example: 
    scripts/rotate_pdf.py
    for PDF rotation tasks
  • Benefits: Token efficient, deterministic, may be executed without loading into context
  • Note: Scripts may still need to be read by an AI for patching or environment-specific adjustments
用于需要确定性可靠性或重复编写的任务的可执行代码（Python/Bash等）。
  • 适用场景：当相同代码需要重复编写，或需要确定性可靠性时
  • 示例：用于PDF旋转任务的
    scripts/rotate_pdf.py
  • 优势：Token效率高、结果确定，无需加载到上下文即可执行
  • 注意：AI可能仍需读取脚本以进行补丁或针对特定环境调整
References (
references/
)
References（
references/
）
Documentation and reference material intended to be loaded as needed into context to inform Claude's process and thinking.
  • When to include: For documentation that Claude should reference while working
  • Examples: 
    references/finance.md
    for financial schemas, 
    references/mnda.md
    for company NDA template, 
    references/policies.md
    for company policies, 
    references/api_docs.md
    for API specifications
  • Use cases: Database schemas, API documentation, domain knowledge, company policies, detailed workflow guides
  • Benefits: Keeps SKILL.md lean, loaded only when Claude determines it's needed
  • Best practice: If files are large (>10k words), include grep search patterns in SKILL.md
  • Avoid duplication: Information should live in either SKILL.md or references files, not both. Prefer references files for detailed information unless it's truly core to the skill—this keeps SKILL.md lean while making information discoverable without hogging the context window. Keep only essential procedural instructions and workflow guidance in SKILL.md; move detailed reference material, schemas, and examples to references files.
供Claude在工作时按需加载到上下文的文档和参考资料，用于指导其流程和思考。
  • 适用场景：Claude工作时需要参考的文档
  • 示例：用于财务schema的
    references/finance.md
    、公司NDA模板
    references/mnda.md
    、公司政策
    references/policies.md
    、API规范
    references/api_docs.md
  • 使用场景：数据库schema、API文档、领域知识、公司政策、详细工作流指南
  • 优势：保持SKILL.md简洁，仅在Claude判定需要时加载
  • 最佳实践：若文件过大（>10000字），在SKILL.md中添加grep搜索模式
  • 避免重复：信息应仅存在于SKILL.md或参考文件中，不可重复。除非是Skill的核心内容，否则优先将详细信息放在参考文件中——这样既能保持SKILL.md简洁，又能让信息可被发现且不占用上下文窗口。仅将必要的流程说明和工作流指导保留在SKILL.md中；将详细参考资料、schema和示例移至参考文件。
Assets (
assets/
)
Assets（
assets/
）
Files not intended to be loaded into context, but rather used within the output Claude produces.
  • When to include: When the skill needs files that will be used in the final output
  • Examples: 
    assets/logo.png
    for brand assets, 
    assets/slides.pptx
    for PowerPoint templates, 
    assets/frontend-template/
    for HTML/React boilerplate, 
    assets/font.ttf
    for typography
  • Use cases: Templates, images, icons, boilerplate code, fonts, sample documents that get copied or modified
  • Benefits: Separates output resources from documentation, enables Claude to use files without loading them into context
无需加载到上下文，而是用于Claude生成的输出中的文件。
  • 适用场景：Skill需要在最终输出中使用文件时
  • 示例：品牌资产
    assets/logo.png
    、PowerPoint模板
    assets/slides.pptx
    、HTML/React模板
    assets/frontend-template/
    、字体文件
    assets/font.ttf
  • 使用场景：模板、图片、图标、样板代码、字体、可复制或修改的示例文档
  • 优势：将输出资源与文档分离，使Claude无需加载到上下文即可使用文件

Progressive Disclosure Design Principle

渐进式披露设计原则

Skills use a three-level loading system to manage context efficiently:
  1. Metadata (name + description) - Always in context (~100 words)
  2. SKILL.md body - When skill triggers (<5k words)
  3. Bundled resources - As needed by Claude (Unlimited*)
*Unlimited because scripts can be executed without reading into context window.
Skill采用三级加载系统以高效管理上下文：
  1. 元数据（名称+描述） - 始终在上下文中（约100字）
  2. SKILL.md 正文 - Skill触发时加载（<5000字）
  3. 捆绑资源 - 由Claude按需加载（*无限制）
*无限制是因为脚本可在不读取到上下文窗口的情况下执行。

Skill Creation Process

Skill 创建流程

To create a skill, follow the "Skill Creation Process" in order, skipping steps only if there is a clear reason why they are not applicable.
要创建Skill，请按“Skill创建流程”顺序执行步骤，仅当明确某步骤不适用时才可跳过。

Step 1: Understanding the Skill with Concrete Examples

步骤1：通过具体示例理解Skill

Skip this step only when the skill's usage patterns are already clearly understood. It remains valuable even when working with an existing skill.
To create an effective skill, clearly understand concrete examples of how the skill will be used. This understanding can come from either direct user examples or generated examples that are validated with user feedback.
For example, when building an image-editor skill, relevant questions include:
  • "What functionality should the image-editor skill support? Editing, rotating, anything else?"
  • "Can you give some examples of how this skill would be used?"
  • "I can imagine users asking for things like 'Remove the red-eye from this image' or 'Rotate this image'. Are there other ways you imagine this skill being used?"
  • "What would a user say that should trigger this skill?"
To avoid overwhelming users, avoid asking too many questions in a single message. Start with the most important questions and follow up as needed for better effectiveness.
Conclude this step when there is a clear sense of the functionality the skill should support.
仅当Skill的使用模式已清晰明了时才可跳过此步骤。即使处理现有Skill，此步骤仍有价值。
要创建高效的Skill，需清晰理解该Skill的具体使用示例。这些理解可来自直接的用户示例，或经用户反馈验证的生成示例。
例如，在构建图片编辑器Skill时，相关问题包括：
  • “图片编辑器Skill应支持哪些功能？编辑、旋转，还是其他？”
  • “能否举例说明该Skill的使用场景？”
  • “我能想到用户会要求‘去除这张图片的红眼’或‘旋转这张图片’。你认为还有其他使用方式吗？”
  • “用户说什么话应该触发这个Skill？”
为避免给用户造成负担，请勿在单条消息中提出过多问题。先从最重要的问题开始，必要时再跟进以提升效果。
当明确Skill应支持的功能时，即可完成此步骤。

Step 2: Planning the Reusable Skill Contents

步骤2：规划可复用的Skill内容

To turn concrete examples into an effective skill, analyze each example by:
  1. Considering how to execute on the example from scratch
  2. Identifying what scripts, references, and assets would be helpful when executing these workflows repeatedly
Example: When building a 
pdf-editor
skill to handle queries like "Help me rotate this PDF," the analysis shows:
  1. Rotating a PDF requires re-writing the same code each time
  2. A 
    scripts/rotate_pdf.py
    script would be helpful to store in the skill
Example: When designing a 
frontend-webapp-builder
skill for queries like "Build me a todo app" or "Build me a dashboard to track my steps," the analysis shows:
  1. Writing a frontend webapp requires the same boilerplate HTML/React each time
  2. An 
    assets/hello-world/
    template containing the boilerplate HTML/React project files would be helpful to store in the skill
Example: When building a 
big-query
skill to handle queries like "How many users have logged in today?" the analysis shows:
  1. Querying BigQuery requires re-discovering the table schemas and relationships each time
  2. A 
    references/schema.md
    file documenting the table schemas would be helpful to store in the skill
To establish the skill's contents, analyze each concrete example to create a list of the reusable resources to include: scripts, references, and assets.
要将具体示例转化为高效Skill，请按以下步骤分析每个示例：
  1. 考虑如何从头开始执行该示例
  2. 确定在重复执行这些工作流时，哪些脚本、参考资料和资产会有帮助
示例：构建用于处理“帮我旋转这个PDF”这类查询的
pdf-editor
Skill时，分析结果如下：
  1. 旋转PDF需要重复编写相同的代码
  2. 在Skill中存储
    scripts/rotate_pdf.py
    脚本会很有帮助
示例：设计用于处理“帮我构建一个待办事项应用”或“帮我构建一个追踪步数的仪表盘”这类查询的
frontend-webapp-builder
Skill时，分析结果如下：
  1. 构建前端Web应用需要重复编写相同的HTML/React样板代码
  2. 在Skill中存储包含HTML/React项目文件的
    assets/hello-world/
    模板会很有帮助
示例：构建用于处理“今天有多少用户登录？”这类查询的
big-query
Skill时，分析结果如下：
  1. 查询BigQuery需要重复查找表schema和关系
  2. 在Skill中存储记录表schema的
    references/schema.md
    文件会很有帮助
要确定Skill的内容，请分析每个具体示例，列出需包含的可复用资源：脚本、参考资料和资产。

Step 3: Initializing the Skill

步骤3：初始化Skill

At this point, it is time to actually create the skill.
Skip this step only if the skill being developed already exists, and iteration or packaging is needed. In this case, continue to the next step.
When creating a new skill from scratch, always run the 
init_skill.py
script. The script conveniently generates a new template skill directory that automatically includes everything a skill requires, making the skill creation process much more efficient and reliable.
Usage:
bash
scripts/init_skill.py <skill-name> --path <output-directory>
The script:
  • Creates the skill directory at the specified path
  • Generates a SKILL.md template with proper frontmatter and TODO placeholders
  • Creates example resource directories: 
    scripts/
    , 
    references/
    , and 
    assets/
  • Adds example files in each directory that can be customized or deleted
After initialization, customize or remove the generated SKILL.md and example files as needed.
此时即可实际创建Skill。
仅当开发的Skill已存在，且需要迭代或打包时才可跳过此步骤。这种情况下，直接进入下一步。
从零开始创建新Skill时，请始终运行
init_skill.py
脚本。该脚本可便捷地生成新的Skill目录模板，自动包含Skill所需的所有内容，使Skill创建过程更高效可靠。
使用方法：
bash
scripts/init_skill.py <skill-name> --path <output-directory>
该脚本会：
  • 在指定路径创建Skill目录
  • 生成带有正确前置元数据和待办占位符的SKILL.md模板
  • 创建示例资源目录：
    scripts/
    、
    references/
    和
    assets/
  • 在每个目录中添加可自定义或删除的示例文件
初始化完成后，根据需要自定义或删除生成的SKILL.md和示例文件。

Step 4: Edit the Skill

步骤4：编辑Skill

When editing the (newly-generated or existing) skill, remember that the skill is being created for another instance of Claude to use. Focus on including information that would be beneficial and non-obvious to Claude. Consider what procedural knowledge, domain-specific details, or reusable assets would help another Claude instance execute these tasks more effectively.
编辑（新生成或现有）Skill时，请记住该Skill是为另一个Claude实例使用而创建的。重点包含对Claude有益且非显而易见的信息。思考哪些程序知识、领域特定细节或可复用资产能帮助另一个Claude实例更高效地执行这些任务。

Start with Reusable Skill Contents

从可复用Skill内容开始

To begin implementation, start with the reusable resources identified above: 
scripts/
, 
references/
, and 
assets/
files. Note that this step may require user input. For example, when implementing a 
brand-guidelines
skill, the user may need to provide brand assets or templates to store in 
assets/
, or documentation to store in 
references/
.
Also, delete any example files and directories not needed for the skill. The initialization script creates example files in 
scripts/
, 
references/
, and 
assets/
to demonstrate structure, but most skills won't need all of them.
开始实现时，先处理上述确定的可复用资源：
scripts/
、
references/
和
assets/
文件。请注意，此步骤可能需要用户输入。例如，在实现
brand-guidelines
Skill时，用户可能需要提供品牌资产或模板以存储在
assets/
中，或提供文档以存储在
references/
中。
此外，删除Skill不需要的示例文件和目录。初始化脚本会在
scripts/
、
references/
和
assets/
中创建示例文件以展示结构，但大多数Skill不需要所有这些文件。

Update SKILL.md

更新SKILL.md

Writing Style: Write the entire skill using imperative/infinitive form (verb-first instructions), not second person. Use objective, instructional language (e.g., "To accomplish X, do Y" rather than "You should do X" or "If you need to do X"). This maintains consistency and clarity for AI consumption.
To complete SKILL.md, answer the following questions:
  1. What is the purpose of the skill, in a few sentences?
  2. When should the skill be used?
  3. In practice, how should Claude use the skill? All reusable skill contents developed above should be referenced so that Claude knows how to use them.
写作风格：整个Skill请使用命令式/不定式形式（动词开头的指令），而非第二人称。使用客观的说明性语言（例如：“要完成X，请执行Y”，而非“你应该做X”或“如果你需要做X”）。这样能保持AI读取时的一致性和清晰度。
要完成SKILL.md，请回答以下问题：
  1. 该Skill的用途是什么？用几句话说明。
  2. 何时应使用该Skill？
  3. 实际操作中，Claude应如何使用该Skill？需引用上述开发的所有可复用Skill内容，以便Claude了解如何使用它们。

Step 5: Packaging a Skill

步骤5：打包Skill

Once the skill is ready, it should be packaged into a distributable zip file that gets shared with the user. The packaging process automatically validates the skill first to ensure it meets all requirements:
bash
scripts/package_skill.py <path/to/skill-folder>
Optional output directory specification:
bash
scripts/package_skill.py <path/to/skill-folder> ./dist
The packaging script will:
  1. Validate the skill automatically, checking:
    • YAML frontmatter format and required fields
    • Skill naming conventions and directory structure
    • Description completeness and quality
    • File organization and resource references
  2. Package the skill if validation passes, creating a zip file named after the skill (e.g., 
    my-skill.zip
    ) that includes all files and maintains the proper directory structure for distribution.
If validation fails, the script will report the errors and exit without creating a package. Fix any validation errors and run the packaging command again.
Skill准备就绪后，应打包为可分发的zip文件并分享给用户。打包过程会先自动验证Skill，确保其符合所有要求：
bash
scripts/package_skill.py <path/to/skill-folder>
可选的输出目录指定：
bash
scripts/package_skill.py <path/to/skill-folder> ./dist
打包脚本会：
  1. 自动验证Skill，检查：
    • YAML前置元数据格式和必填字段
    • Skill命名规范和目录结构
    • 描述的完整性和质量
    • 文件组织和资源引用情况
  2. 打包Skill（若验证通过），创建以Skill命名的zip文件（例如：
    my-skill.zip
    ），包含所有文件并保持正确的目录结构以便分发。
若验证失败，脚本会报告错误并退出，不创建包。修复所有验证错误后，重新运行打包命令。

Step 6: Iterate

步骤6：迭代

After testing the skill, users may request improvements. Often this happens right after using the skill, with fresh context of how the skill performed.
Iteration workflow:
  1. Use the skill on real tasks
  2. Notice struggles or inefficiencies
  3. Identify how SKILL.md or bundled resources should be updated
  4. Implement changes and test again
测试Skill后，用户可能会要求改进。通常这会在使用Skill后立即发生，此时用户对Skill的表现有清晰的印象。
迭代工作流：
  1. 在实际任务中使用Skill
  2. 发现问题或低效之处
  3. 确定应如何更新SKILL.md或捆绑资源
  4. 实施更改并再次测试
