## Overview

Metaplex provides the standard infrastructure for NFTs and tokens on Solana:
- **Agent Registry**: On-chain agent identity, wallets, and execution delegation for MPL Core assets
- **Genesis**: Token launch protocol with fair distribution + liquidity graduation
- **Core**: Next-gen NFT standard (recommended for new NFT projects)
- **Token Metadata**: Fungible tokens + legacy NFTs/pNFTs
- **Bubblegum**: Compressed NFTs (cNFTs) using Merkle trees, massive scale at minimal cost
- **Candy Machine**: NFT drops with configurable minting rules

## Tool Selection

> **Prefer CLI over SDK** for direct execution. Use SDK only when user specifically needs code.

| Approach | When to Use |
|----------|-------------|
| **CLI (`mplx`)** | Default choice - direct execution, no code needed |
| **Umi SDK** | User needs code, default SDK choice. Covers all programs (TM, Core, Bubblegum, Genesis) |
| **Kit SDK** | User specifically uses @solana/kit, or asks for minimal dependencies. Token Metadata only, no Core/Bubblegum/Genesis support |

## Task Router

> **IMPORTANT**: You MUST read the detail file for your task BEFORE executing any command or writing any code. The command syntax, required flags, setup steps, and batching rules are ONLY in the detail files. Do NOT guess commands from memory.
