The Claude Plugins Marketplace is a web application used to discover, browse, and find installation instructions for Claude Code plugins and skills.

Key capabilities include:

• Plugin Browser: Search through a collection of over 1200 Claude Code plugins.
• Skills Discovery: Browse skills with dedicated filtering and search functionality.
• Skill Documentation: View detailed documentation for individual skills rendered via markdown.
• Installation: Access quick-start copy-paste commands to install skills easily.
• Real-time Search: Use client-side search that supports URL parameters for sharing specific search states.

Claude Plugins are collections of slash commands, agents, MCP servers, and hooks that extend Claude Code's functionality. They allow for custom shortcuts, purpose-built agents, and external tool connections via the Model Context Protocol (MCP).

Requirement: You must have Claude Code v2.0.12 or later installed.

Both claude-plugins and skills-installer resolve identifiers (e.g., @owner/repo/name) via a central registry. The process follows these steps:

1. The user runs an install command with a specific identifier.
2. The registry returns the corresponding Git repository URL.
3. The CLI clones and installs the plugin or skill directly from that repository.

By default, skills are installed globally. To install a skill so that it is only available within the current project directory, use the --project or -p flag.

skills-installer install anthropics/claude-code/pdf --project
# or
skills-installer install anthropics/claude-code/pdf -p

You can use the --client <name> option to specify which AI coding client the skill should be installed for. This determines the installation path.

Supported clients:

• shared: Installs to .agents/skills (used by Codex, Amp, Warp, Cursor, OpenCode, Cline, Gemini CLI, GitHub Copilot, etc.). You can also use aliases like opencode, codex, cursor, cline, amp, warp, or github-copilot.
• claude-code: Installs to .claude/skills.
• openclaw: Installs to skills (project) or ~/.openclaw/skills (global).
• pi: Installs to .pi/skills (project) or ~/.pi/agent/skills (global).

skills-installer install @anthropics/skills/xlsx --client shared

You can install the skills-installer CLI tool globally via npm to manage agent skills across different AI coding clients.

Alternatively, you can run it without a permanent installation using npx.

npm install -g skills-installer

Or use directly with npx:

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

Use the search command to find skills across all public GitHub repositories. This command launches an interactive interface where you can browse and sort skills by relevance, installs, and GitHub stars. You can then select a skill to install, choose its installation scope (global or project), and select the target client.

# Search across all public skills interactively
skills-installer search

# Search with a specific query
skills-installer search "frontend design"

To see which skills are currently installed on your system, use the list command. It shows the installation scope (global or project) and the file paths. To update an existing skill, simply run the install command for that skill again; it will automatically perform an update.

# List all installed skills
skills-installer list

# Update an existing skill
skills-installer install anthropics/claude-code/frontend-design

You can quickly install plugins or skills using npx without a global installation.

Install a Claude plugin: Requires Claude Code v2.0.12 or later.

Install an agent skill: Works with agentskills-compatible clients. Check agentskills.io to verify client support.

# Install a Claude plugin
npx claude-plugins install @EveryInc/every-marketplace/compound-engineering

# Install an agent skill
npx skills-installer install @anthropics/claude-code/frontend-design

The install command (and its alias add) is used to fetch and install skills. You can specify skills using various identifier formats, including owners, repositories, specific skill paths, or direct GitHub URLs.

# Browse all skills from an owner
skills-installer install anthropics

# Browse skills in a specific repo
skills-installer install anthropics/claude-code

# Install a specific skill
skills-installer install anthropics/claude-code/frontend-design

# Install all skills resolved from an owner or repo
skills-installer install anthropics/claude-code --all

# Install from any GitHub URL
skills-installer install https://github.com/owner/repo/tree/main/skills/my-skill

# `add` is an alias for `install`
skills-installer add anthropics/claude-code/frontend-design

You can install the claude-plugins CLI globally via npm to manage Claude Code plugins from your terminal. Alternatively, you can run commands directly using npx without a global installation.

Plugins are installed to the following directory: ~/.claude/plugins/marketplaces/.

npm install -g claude-plugins

Or use directly with npx

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