# shared

Helps you write new skills and clean up existing ones: structure, front matter, splitting into modules. Useful once your agent starts losing track of your instructions.

## What it does

The skill activates when you ask to create a skill, ask about skill structure, or want to refactor an old one. It ships one module, `skill-creator/`: templates for simple and modular skills, a walkthrough of YAML front matter, modularization patterns, and a list of common pitfalls. The flow is short — figure out what you need, read the module files, apply them to your case.

Tools are plain: `Read`, `Write`, `Glob`, `Grep`, `Bash`. Nothing extra to install, and no magic either — this is a set of text templates and advice, not a code generator. If you already have your own skill format, expect to adapt the templates by hand.

Worth it when you maintain several skills and want them consistent. For a single small skill you won't notice the difference.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add rshankras/claude-code-apple-skills --skill shared -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/shared/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/shared/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add rshankras/claude-code-apple-skills --skill shared -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/shared/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add rshankras/claude-code-apple-skills --skill shared -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/shared/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install rshankras/claude-code-apple-skills shared
```

2. **Manually: put the files in place**
- File: `.github/skills/shared/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add rshankras/claude-code-apple-skills --skill shared -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/rshankras/claude-code-apple-skills --path skills/shared
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/shared/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add rshankras/claude-code-apple-skills --skill shared -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/rshankras/claude-code-apple-skills/tree/HEAD/skills/shared/SKILL.md

## When to use it
- create a new skill from a template
- split an oversized skill into modules
- get YAML front matter right
- rewrite an old skill to match current structure
- figure out why the agent ignores your instructions

## Example prompts
- help me create a new skill for handling migrations
- split my skill into modules, it has grown too big
- check the front matter in `~/.claude/skills/shared/SKILL.md`

# Shared Skills

Platform-agnostic skills that work across iOS, macOS, and other Apple platforms. This category provides foundational tools for extending Claude Code's capabilities.

## When This Skill Activates

Use this skill when the user:
- Wants to create a new Claude Code skill
- Asks about skill structure or organization
- Wants to improve or refactor existing skills
- Needs help with skill modularization
- Asks about skill best practices or templates

## Available Modules

Read relevant module files based on the user's needs:

### skill-creator/
Templates and guidance for creating well-structured Claude Code skills.
- Skill structure and organization patterns
- YAML front matter configuration
- Modularization strategies
- Templates for simple and complex skills
- Best practices and common pitfalls

## How to Use

1. Identify user's need from their question
2. Read relevant module files from subdirectories
3. Apply the guidance to their specific context
4. Provide examples from existing skills when helpful

## Example Workflow

**User wants to create a new skill:**
1. Read `skill-creator/SKILL.md` for the full creation process
2. Determine skill complexity (simple vs modularized)
3. Guide through front matter, structure, and content
4. Reference existing skills as examples
```
