What it solves

This project provides a marketplace of production-ready "skills" (plugins) for Claude Code, extending its capabilities for software development, documentation, financial analysis, and system operations. It specifically addresses the difficulty of creating high-quality, stable skills by providing a hardened skill-creator tool that guides users through a rigorous development, validation, and packaging process.

How it works

Users install the marketplace via the Claude Code /plugin command or CLI. Once added, they can install individual skills or "suites" (bundles of related skills). The skill-creator meta-skill acts as a framework for building new skills, implementing a structured search protocol for MCPs, security scans via gitleaks, and structural validators to ensure the resulting plugins are production-grade.

Who it’s for

• Claude Code users looking to automate specific workflows like GitHub operations, financial research, or document conversion.
• Skill developers who want a professional framework to build, validate, and package their own Claude Code extensions.
• Power users needing advanced system utilities (e.g., macOS cleaners, statusline customization, or session recovery).

Highlights

• Skill-Creator Meta-Skill: A production-hardened fork of the official creator with added security gates, risk-tier evaluation, and failure pattern documentation.
• Diverse Skill Suites: Bundled plugins for documentation (PDF/PPTX to Markdown), Apple platform development, financial data analysis (yfinance, sentiment analysis), and Claude Code power-user operations.
• GitHub Operations: A dedicated suite for managing PRs, issues, and organization permissions via the gh CLI.
• Utility Tools: Includes specialized tools for Mermaid diagram generation, Repomix extraction, and professional CLI demo recording via VHS.
