AgentFoundry Plugin Marketplace

Curated collection of Claude Code plugins for AI agent development — skills, commands, hooks, and agents.

Quick Start

1. Add the Marketplace

In Claude Code, run:

/plugin marketplace add Shawn-Guo-CN/agentfoundry-plugin-marketplace

This registers the marketplace so Claude Code can discover all plugins listed here.

2. Browse Available Plugins

/plugin

Navigate to Discover to see all available plugins from this marketplace.

3. Install a Plugin

/plugin install <plugin-name>@agentfoundry-plugin-marketplace

For example:

/plugin install commit-commands@agentfoundry-plugin-marketplace
/plugin install planning-with-files@agentfoundry-plugin-marketplace

4. Use the Plugin

Once installed, plugins activate automatically based on their type:

• Skills — Claude loads them when relevant context is detected
• Commands — Use slash commands directly (e.g. /commit, /plan)
• Hooks — Trigger automatically on lifecycle events (PreToolUse, PostToolUse, etc.)
• Agents — Available as subagents for delegation via the Task tool
