Claude Plugins

A plugin manager and skills installer for AI coding agents.

Quick Start

Install a Claude plugin:

npx claude-plugins install @EveryInc/every-marketplace/compounding-engineering

Important

Requires Claude Code v2.0.12 or later for plugin support.

Install an agent skill (works with agentskills-compatible clients):

npx skills-installer install @anthropics/claude-code/frontend-design

Important

Check agentskills to see if your client supports skills.

Why Use This?

Discovering, installing, and managing plugins and skills across AI coding agents can be fragmented. This project provides:

• One registry for discovering 9,595 Claude Code plugins and 52,128 agent skills at claude-plugins.dev
• Two focused CLIs — claude-plugins for Claude Code plugins, skills-installer for agent skills
• Multi-client support — Install skills for Claude, Cursor, OpenCode, Codex, VS Code, Amp Code, Goose, Letta.

Discover

Explore available Claude Code plugins and agent skills at claude-plugins.dev

Our registry automatically discovers and indexes all public Claude Code plugins and agent skills on GitHub.

Two CLI Tools

This project provides two command-line tools:

claude-plugins

Manage Claude Code plugins — install, enable, disable, and list.

npm install -g claude-plugins

Command	Description
install <plugin>	Install a plugin from the registry
list	View installed plugins
enable <name>	Enable a disabled plugin
disable <name>	Disable a plugin

Plugins are installed to ~/.claude/plugins/marketplaces/

skills-installer

Install Agent Skills across multiple AI coding clients.

npm install -g skills-installer

Command	Description
install <skill>	Install or update a skill
list	List installed skills

Options:

• --client <name> — Target client (default: claude-code)
• --local or -l — Install to current directory only

Skills are installed to ~/.claude/skills/ (global) or ./.claude/skills/ (local)

Supported Clients

Client	Flag
Claude Code	--client claude-code (default)
Cursor	--client cursor
VS Code	--client vscode
Codex	--client codex
Amp Code	--client amp
OpenCode	--client opencode
Goose	--client goose
Letta	--client letta
GitHub	--client github

How It Works

Both tools resolve identifiers via our registry:

1. Run install command with identifier (e.g., @owner/repo/name)
2. Registry returns the Git repository URL
3. CLI clones and installs the plugin or skill
