# Skill Instructions

Detailed instructions for what the skill should do.

Register in marketplace.json

Add the new plugin to .claude-plugin/marketplace.json:

{
  "plugins": [
    {
      "name": "new-plugin",
      "source": "./plugins/new-plugin",
      "description": "Plugin description"
    }
  ]
}

Testing

claude --plugin-dir ./plugins/<plugin-name>

Using Complex Scripts

When complex logic is needed:

1. Create bash scripts in scripts/ directory
2. Reference script execution in SKILL.md
3. Only script output goes to context, making it token-efficient
