🔍 Understanding Plugin Types

This marketplace contains two types of plugins that work differently:

1. 🤖 AI Instruction Plugins (Plugin Packs & Templates)

• What they are: Detailed markdown instructions that guide Claude's behavior
• How they work: Tell Claude HOW to perform tasks using its built-in capabilities
• Examples: DevOps pack, Security pack, AI Agency toolkit
• No external code execution - work entirely through Claude's interpretation

2. ⚙️ MCP Server Plugins (Executable Code)

• What they are: Real TypeScript/JavaScript applications
• How they work: Run as separate Node.js processes that Claude can communicate with
• Examples: project-health-auditor, conversational-api-debugger
• Actual compiled code - 13-26KB of executable JavaScript

Both types are fully functional but operate through different mechanisms. Most plugins in this marketplace are AI instruction templates designed specifically for Claude Code.
