Claude Code Skills Marketplace

This is a Claude Code Marketplace repository: used to distribute plugins that extend Claude Code with skills, slash commands, hooks, custom agents, and protocol servers (MCP, LSP).

How marketplaces work:

1. Add a marketplace to your Claude Code installation (one-time setup)
2. Claude Code reads the marketplace catalog to discover available plugins
3. Install individual plugins selectively
4. Receive automatic updates when plugin versions change

Quick Start

1. Add this marketplace

/plugin marketplace add Mearman/marketplace

2. Install a plugin from the list below

For example, to install the Wayback Machine Archive plugin:

/plugin install wayback@mearman

3. Use the skill

Ask: "Check if example.com is archived in the Wayback Machine"
