Plugin Development

Key Concepts

• Skills (skills/*/SKILL.md) - Auto-invoked by Claude based on task context
• Commands (commands/*.md) - User-invoked via slash commands (/plugin:command)
• Agents (agents/*.md) - Specialized Claude personas for complex tasks
• Hooks (hooks/hooks.json) - Event handlers for git operations and file changes
