What it solves

This project provides a centralized, validated marketplace for plugins and skills designed specifically for Claude Code (Anthropic's official CLI). It eliminates the need for manual synchronization of registries and ensures that all available tools are spec-compliant and production-ready.

How it works

The repository acts as a canonical catalog where plugins are defined in a marketplace.extended.json file. It uses a dedicated CLI tool (ccpi) and a validator to ensure every plugin adheres to the AgentSkills.io open standard and Claude Code's official references. The project also includes a "forge" feature (/skill-creator --forge) that can automatically generate production-grade plugins from any REST API.

Who it’s for

Developers and users of Claude Code who want to extend the CLI's capabilities with a vast library of pre-validated skills across various domains like DevOps, AI/ML, and API development.

Highlights

• Massive Library: Contains 471 plugins, 3,679 skills, and 347 agents.
• Strict Validation: Every plugin is tested against a 100-point rubric and the Intent Solutions validator to prevent "C-grade" submissions.
• Easy Installation: Supports installation via a custom CLI (ccpi) or directly through Claude Code's built-in /plugin commands.
• Automated Generation: Ability to build plugins from REST APIs with a full audit trail.
• Production Patterns: Includes playbooks and a wiki to handle scale-related issues like rate limits and MCP reliability.
