# 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.

**IMPORTANT:**
- Skills are not documentation, they are practical instructions for Claude Code to use the tools, packages, plugins or APIs to achieve the tasks.
- Each skill teaches Claude how to perform a specific development task, not what a tool does.
- Claude Code can activate multiple skills automatically to achieve the user's request.

### 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

### Anatomy of a Skill

Every skill consists of a required SKILL.md file and optional bundled resources:

        ├── references/       - Documentation intended to be loaded into context as needed
        └── assets/           - Files used in output (templates, icons, fonts, etc.)
```

#### Requirements (**IMPORTANT**)

- Skill should be combined into specific topics, for example: `cloudflare`, `cloudflare-r2`, `cloudflare-workers`, `docker`, `gcloud` should be combined into `devops`
- `SKILL.md` should be **less than 150 lines** and include the references of related markdown files and scripts.
- Each script or referenced markdown file should be also **less than 150 lines**, remember that you can always split them into multiple files (**progressive disclosure** principle).
- Descriptions in metadata of `SKILL.md` files should be both concise (**less than 200 characters**) and still contains enough usecases of the references and scripts, this will help skills can be activated automatically during the implementation process of Claude Code.
- **Referenced markdowns**:
  - Sacrifice grammar for the sake of concision when writing these files.
  - Can reference other markdown files or scripts as well.
- **Referenced scripts**:
  - Prefer nodejs or python scripts instead of bash script, because bash scripts are not well-supported on Windows.
  - If you're going to write python scripts, make sure you have `requirements.txt`
  - Make sure scripts respect `.env` file follow this order: `process.env` > `$HOME/.claude/skills/${SKILL}/.env` (global) > `$HOME/.claude/skills/.env` (global) > `$HOME/.claude/.env` (global) > `./.claude/skills/${SKILL}/.env` (cwd) > `./.claude/skills/.env` (cwd) > `./.claude/.env` (cwd)
  - Create `.env.example` files to show the required environment variables.
  - Always write tests for these scripts.

**IMPORTANT:**
- Always keep in mind that `SKILL.md` and reference files should be token consumption efficient, so that **progressive disclosure** can be leveraged at best.
- `SKILL.md` should be **less than 150 lines**
- Referenced markdown files should be also **less than 150 lines**, remember that you can always split them into multiple files (**progressive disclosur
