This project provides a lightweight registry and command-line interface (CLI) tools for discovering, installing, and managing plugins and agent skills for AI coding agents. It addresses the fragmentation in managing these extensions across different AI development environments, offering a unified solution for users of tools like Claude Code, Cursor, and VS Code. The primary benefit is simplified access to a vast ecosystem of AI agent enhancements.

How It Works

The system utilizes a central registry, accessible at claude-plugins.dev, which automatically discovers and indexes public Claude Code plugins and agent skills hosted on GitHub. Two distinct CLI tools, claude-plugins and skills-installer, resolve user-provided identifiers (e.g., @owner/repo/name) against this registry. Upon resolution, the registry returns the corresponding Git repository URL, which the respective CLI then clones to install the plugin or skill. The backend tech stack includes Bun for CLI development, Val Town for the registry API, and Astro for the web application.

Quick Start & Requirements

To install a Claude plugin, use: npx claude-plugins install @EveryInc/every-marketplace/compounding-engineering. For agent skills, use: npx skills-installer install @anthropics/claude-code/frontend-design. Plugin support requires Claude Code v2.0.12 or later. Agent skill compatibility depends on the client supporting agentskills. Both CLIs can be installed globally via npm: npm install -g claude-plugins and npm install -g skills-installer. The project supports multiple clients including Claude Code, Cursor, VS Code, Codex, Amp Code, OpenCode, Goose, Letta, and GitHub.

Highlighted Details

• The registry indexes a substantial collection: 9,595 Claude Code plugins and 52,128 agent skills.
• Provides two focused CLIs: claude-plugins for managing Claude Code plugins and skills-installer for agent skills.
• Offers multi-client support for installing agent skills across various AI coding environments.
• Automatic discovery mechanism ensures the registry stays updated with public GitHub repositories.

Maintenance & Community

Contributions are welcomed via issues or pull requests. Specific community channels (like Discord/Slack), roadmap links, or notable contributors are not detailed in the provided README.

Licensing & Compatibility

The project is released under the MIT license. This permissive license generally allows for commercial use and integration into closed-source projects without significant restrictions.

Limitations & Caveats

Plugin functionality is contingent on using Claude Code version 2.0.12 or newer. Agent skill installation requires the target client to be compatible with the agentskills framework. The registry's comprehensiveness relies on the discoverability of public GitHub repositories containing plugins and skills.
