Using in Your Skill Package

Add this installer as a dependency in your skill's package.json:

{
  "name": "@your-org/your-skill",
  "version": "1.0.0",
  "scripts": {
    "postinstall": "agent-skill-installer install",
    "preuninstall": "agent-skill-installer uninstall"
  },
  "dependencies": {
    "@agentskill/installer": "^1.0.0"
  },
  "files": [
    "SKILL.md",
    "scripts/"
  ]
}

File Structure

The installer will automatically copy the following files if they exist:

• SKILL.md (required) - Main skill definition
• scripts/ (optional) - Utility scripts
• references/ (optional) - Reference documentation
• assets/ (optional) - Templates, icons, etc.

How It Works

Installation Flow

1. Context Detection: Determines if this is a global or project-level installation
2. Config Reading: Reads package.json for the skill name
3. Path Resolution: Calculates the correct installation path (defaults to ~/.claude/skills/)
4. File Copying: Copies SKILL.md and optional directories to the target directory
5. Manifest Update: Updates .skills-manifest.json to track installation

Installation Paths

• Global: ~/.claude/skills/your-skill-name/
• Project: .claude/skills/your-skill-name/

Examples

Install with verbose output

agent-skill-installer install --verbose

Preview installation without changes

agent-skill-installer install --dry-run

Force reinstall

agent-skill-installer install --force

Troubleshooting

Skill not appearing after installation

1. Check if installation was successful:

   agent-skill-installer list

2. Verify the skill directory exists:

   ls -la ~/.claude/skills/

3. Restart your AI coding tool

Permission errors

If you encounter permission errors during global installation:

# Option 1: Fix npm permissions (recommended)
mkdir ~/.npm-global
npm config set prefix '~/.npm-global'
export PATH=~/.npm-global/bin:$PATH

# Option 2: Use sudo (not recommended)
sudo npm install -g @agentskill/installer

Configuration not found

Make sure package.json exists in your package root:

agent-skill-installer install --config /path/to/package.json
