# Skill Creator
本技能提供创建高效技能的指导。
## 关于技能
技能是模块化、自包含的包,通过提供专门知识、工作流程和工具来扩展 Claude 的能力。可以将它们视为特定领域或任务的“入职指南”——它们将 Claude 从通用代理转变为具备程序性知识的专用代理,而这些知识是任何模型都无法完全拥有的。
### 技能提供的内容
1. 专门的工作流程 - 针对特定领域的多步骤流程
2. 工具集成 - 用于处理特定文件格式或 API 的说明
3. 领域专长 - 公司特定的知识、模式、业务逻辑
4. 捆绑资源 - 用于复杂和重复任务的脚本、参考和资源
## 核心原则
### 简洁为王
上下文窗口是一种公共资源。技能需要与系统提示、对话历史、其他技能的元数据以及实际用户请求共享上下文窗口。
**默认假设:Claude 已经非常聪明。** 仅添加 Claude 尚未掌握的上下文。对每一条信息提出质疑:“Claude 真的需要这个解释吗?”以及“这段文字是否值得其消耗的 token 成本?”
优先使用简洁的示例,而非冗长的解释。
### 设定适当的自由度
根据任务的脆弱性和可变性来匹配具体程度:
**高自由度(基于文本的说明)**:当多种方法都有效、决策依赖于上下文或方法由启发式规则引导时使用。
**中等自由度(带参数的伪代码或脚本)**:当存在首选模式、可接受一定程度的变化或配置影响行为时使用。
**低自由度(具体脚本,少量参数)**:当操作脆弱且容易出错、一致性至关重要或必须遵循特定顺序时使用。
将 Claude 想象为在一条路径上探索:狭窄的桥上有悬崖需要具体的护栏(低自由度),而开阔的田野允许多种路线(高自由度)。
### 技能的构成
每个技能包含一个必需的 SKILL.md 文件和可选的捆绑资源:
```
skill-name/
├── SKILL.md (required)
│ ├── YAML frontmatter metadata (required)
│ │ ├── name: (required)
│ │ └── description: (required)
│ └── Markdown instructions (required)
└── Bundled Resources (optional)
├── scripts/ - Executable code (Python/Bash/etc.)
├── references/ - Documentation intended to be loaded into context as needed
└── assets/ - Files used in output (templates, icons, fonts, etc.)
```
#### SKILL.md(必需)
每个 SKILL.md 包含:
- **前置内容**(YAML):包含 `name` 和 `description` 字段。这些是 Claude 用于判断何时使用该技能的唯一字段,因此清晰全面地描述技能内容及其使用场景非常重要。
- **正文**(Markdown):使用该技能的说明和指导。仅在技能触发后(如果有的话)才会加载。
#### 捆绑资源(可选)
##### 脚本(`scripts/`)
用于需要确定性可靠性或反复重写的任务的可执行代码(Python/Bash 等)。
- **何时包含**:当相同代码被反复重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`
- **优点**:节省 token,具有确定性,可能无需加载到上下文中即可执行
- **注意**:脚本仍可能需要被 Claude 读取以进行修补或环境特定调整
##### 参考资料 (`references/`)
旨在根据需要加载到上下文中的文档和参考资料,用于指导 Claude 的处理和思考过程。
- **何时包含**:当 Claude 在工作过程中需要参考文档时
- **示例**:`references/finance.md` 用于财务模式,`references/mnda.md` 用于公司 NDA 模板,`references/policies.md` 用于公司政策,`references/api_docs.md` 用于 API 规范
- **使用场景**:数据库模式、API 文档、领域知识、公司政策、详细工作流程指南
- **优势**:保持 SKILL.md 简洁,仅在 Claude 判断需要时才加载
- **最佳实践**:如果文件较大(>10k 词),请在 SKILL.md 中包含 grep 搜索模式
- **避免重复**:信息应仅存在于 SKILL.md 或参考资料文件中,不可两者同时存在。
##### 资源文件 (`assets/`)
不打算加载到上下文中的文件,而是用于 Claude 生成的输出内容中。
- **何时包含**:当技能需要在最终输出中使用的文件时
- **示例**:`assets/logo.png` 用于品牌资产,`assets/slides.pptx` 用于 PowerPoint 模板
- **使用场景**:模板、图像、图标、样板代码、字体、示例文档
### 渐进式披露设计原则
技能采用三级加载系统,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 词)
2. **SKILL.md 正文** - 技能触发时加载(<5k 词)
3. **捆绑资源** - 由 Claude 按需加载
请将 SKILL.md 正文控制在核心内容范围内,并少于 500 行,以尽量减少上下文膨胀。
## 技能创建流程
技能创建包含以下步骤:
1. 使用具体示例理解技能
2. 规划可复用的技能内容(脚本、参考资料、资源文件)
3. 初始化技能(运行 init_skill.py)
4. 编辑技能(实现资源并编写 SKILL.md)
5. 打包技能(运行 package_skill.py)
6. 根据实际使用情况迭代优化
### 第 3 步:初始化技能
从零开始创建新技能时,始终运行 `init_skill.py` 脚本:
```bash
scripts/init_skill.py <skill-name> --path <output-directory>
```
### 第 4 步:编辑技能
根据您的技能需求,参考以下有用指南:
- **多步骤流程**:参见 references/workflows.md 了解顺序工作流和条件逻辑
- **特定输出格式或质量标准**:参见 references/output-patterns.md 了解模板和示例模式
### 第 5 步:打包技能
```bash
scripts/package_skill.py <path/to/skill-folder>
```
打包脚本将验证并生成用于分发的 .skill 文件。
FILE:references/workflows.md
# 工作流模式
## 顺序工作流
对于复杂任务,将操作分解为清晰的顺序步骤。通常在 SKILL.md 开头部分向 Claude 提供流程概览会很有帮助:
```markdown
Filling a PDF form involves these steps:
1. Analyze the form (run analyze_form.py)
2. Create field mapping (edit fields.json)
3. Validate mapping (run validate_fields.py)
4. Fill the form (run fill_form.py)
5. Verify output (run verify_output.py)
```
## 条件工作流
对于具有分支逻辑的任务,请引导 Claude 经历各个决策点:
```markdown
1. Determine the modification type:
**Creating new content?** → Follow "Creation workflow" below
**Editing existing content?** → Follow "Editing workflow" below
2. Creation workflow: [steps]
3. Editing workflow: [steps]
```
FILE:references/output-patterns.md
# 输出模式
当技能需要生成一致且高质量的输出时,请使用以下模式。
## 模板模式
为输出格式提供模板。根据您的需求匹配严格的程度。
**对于严格要求(如 API 响应或数据格式):**
```markdown
## Report structure
ALWAYS use this exact template structure:
# [Analysis Title]
## Executive summary
[One-paragraph overview of key findings]
## Key findings
- Finding 1 with supporting data
- Finding 2 with supporting data
- Finding 3 with supporting data
## Recommendations
1. Specific actionable recommendation
2. Specific actionable recommendation
```
**对于灵活指导(当需要适应性时):**
```markdown
## Report structure
Here is a sensible default format, but use your best judgment:
# [Analysis Title]
## Executive summary
[Overview]
## Key findings
[Adapt sections based on what you discover]
## Recommendations
[Tailor to the specific context]
Adjust sections as needed for the specific analysis type.
```
## 示例模式
对于输出质量依赖于示例的技能,请提供输入/输出配对示例:
```markdown
## Commit message format
Generate commit messages following these examples:
**Example 1:**
Input: Added user authentication with JWT tokens
Output:
```
添加登录端点和令牌验证中间件
```
**Example 2:**
Input: Fixed bug where dates displayed incorrectly in reports
Output:
```
fix(reports): 修正时区转换中的日期格式
在报告生成过程中始终使用 UTC 时间戳
```
Follow this style: type(scope): brief description, then detailed explanation.
```
示例比单纯的描述更能帮助 Claude 清晰理解所需的风格和细节程度。

# Skill Creator
This skill provides guidance for creating effective skills.
## About Skills
Skills are modular, self-contained packages that extend Claude's capabilities by providing
specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific
domains or tasks—they transform Claude from a general-purpose agent into a specialized agent
equipped with procedural knowledge that no model can fully possess.
### What Skills Provide
1. Specialized workflows - Multi-step procedures for specific domains
2. Tool integrations - Instructions for working with specific file formats or APIs
3. Domain expertise - Company-specific knowledge, schemas, business logic
4. Bundled resources - Scripts, references, and assets for complex and repetitive tasks
## Core Principles
### Concise is Key
The context window is a public good. Skills share the context window with everything else Claude needs: system prompt, conversation history, other Skills' metadata, and the actual user request.
**Default assumption: Claude is already very smart.** Only add context Claude doesn't already have. Challenge each piece of information: "Does Claude really need this explanation?" and "Does this paragraph justify its token cost?"
Prefer concise examples over verbose explanations.
### Set Appropriate Degrees of Freedom
Match the level of specificity to the task's fragility and variability:
**High freedom (text-based instructions)**: Use when multiple approaches are valid, decisions depend on context, or heuristics guide the approach.
**Medium freedom (pseudocode or scripts with parameters)**: Use when a preferred pattern exists, some variation is acceptable, or configuration affects behavior.
**Low freedom (specific scripts, few parameters)**: Use when operations are fragile and error-prone, consistency is critical, or a specific sequence must be followed.
Think of Claude as exploring a path: a narrow bridge with cliffs needs specific guardrails (low freedom), while an open field allows many routes (high freedom).
### Anatomy of a Skill
Every skill consists of a required SKILL.md file and optional bundled resources:
```
skill-name/
├── SKILL.md (required)
│ ├── YAML frontmatter metadata (required)
│ │ ├── name: (required)
│ │ └── description: (required)
│ └── Markdown instructions (required)
└── Bundled Resources (optional)
├── scripts/ - Executable code (Python/Bash/etc.)
├── references/ - Documentation intended to be loaded into context as needed
└── assets/ - Files used in output (templates, icons, fonts, etc.)
```
#### SKILL.md (required)
Every SKILL.md consists of:
- **Frontmatter** (YAML): Contains `name` and `description` fields. These are the only fields that Claude reads to determine when the skill gets used, thus it is very important to be clear and comprehensive in describing what the skill is, and when it should be used.
- **Body** (Markdown): Instructions and guidance for using the skill. Only loaded AFTER the skill triggers (if at all).
#### Bundled Resources (optional)
##### 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 Claude for patching or environment-specific adjustments
##### 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.
##### 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
- **Use cases**: Templates, images, icons, boilerplate code, fonts, sample documents
### Progressive Disclosure Design Principle
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
Keep SKILL.md body to the essentials and under 500 lines to minimize context bloat.
## Skill Creation Process
Skill creation involves these steps:
1. Understand the skill with concrete examples
2. Plan reusable skill contents (scripts, references, assets)
3. Initialize the skill (run init_skill.py)
4. Edit the skill (implement resources and write SKILL.md)
5. Package the skill (run package_skill.py)
6. Iterate based on real usage
### Step 3: Initializing the Skill
When creating a new skill from scratch, always run the `init_skill.py` script:
```bash
scripts/init_skill.py <skill-name> --path <output-directory>
```
### Step 4: Edit the Skill
Consult these helpful guides based on your skill's needs:
- **Multi-step processes**: See references/workflows.md for sequential workflows and conditional logic
- **Specific output formats or quality standards**: See references/output-patterns.md for template and example patterns
### Step 5: Packaging a Skill
```bash
scripts/package_skill.py <path/to/skill-folder>
```
The packaging script validates and creates a .skill file for distribution.
FILE:references/workflows.md
# Workflow Patterns
## Sequential Workflows
For complex tasks, break operations into clear, sequential steps. It is often helpful to give Claude an overview of the process towards the beginning of SKILL.md:
```markdown
Filling a PDF form involves these steps:
1. Analyze the form (run analyze_form.py)
2. Create field mapping (edit fields.json)
3. Validate mapping (run validate_fields.py)
4. Fill the form (run fill_form.py)
5. Verify output (run verify_output.py)
```
## Conditional Workflows
For tasks with branching logic, guide Claude through decision points:
```markdown
1. Determine the modification type:
**Creating new content?** → Follow "Creation workflow" below
**Editing existing content?** → Follow "Editing workflow" below
2. Creation workflow: [steps]
3. Editing workflow: [steps]
```
FILE:references/output-patterns.md
# Output Patterns
Use these patterns when skills need to produce consistent, high-quality output.
## Template Pattern
Provide templates for output format. Match the level of strictness to your needs.
**For strict requirements (like API responses or data formats):**
```markdown
## Report structure
ALWAYS use this exact template structure:
# [Analysis Title]
## Executive summary
[One-paragraph overview of key findings]
## Key findings
- Finding 1 with supporting data
- Finding 2 with supporting data
- Finding 3 with supporting data
## Recommendations
1. Specific actionable recommendation
2. Specific actionable recommendation
```
**For flexible guidance (when adaptation is useful):**
```markdown
## Report structure
Here is a sensible default format, but use your best judgment:
# [Analysis Title]
## Executive summary
[Overview]
## Key findings
[Adapt sections based on what you discover]
## Recommendations
[Tailor to the specific context]
Adjust sections as needed for the specific analysis type.
```
## Examples Pattern
For skills where output quality depends on seeing examples, provide input/output pairs:
```markdown
## Commit message format
Generate commit messages following these examples:
**Example 1:**
Input: Added user authentication with JWT tokens
Output:
```
feat(auth): implement JWT-based authentication
Add login endpoint and token validation middleware
```
**Example 2:**
Input: Fixed bug where dates displayed incorrectly in reports
Output:
```
fix(reports): correct date formatting in timezone conversion
Use UTC timestamps consistently across report generation
```
Follow this style: type(scope): brief description, then detailed explanation.
```
Examples help Claude understand the desired style and level of detail more clearly than descriptions alone.
