Claude Code Skills - Engineering Marketplace

A curated collection of engineering-focused skills and plugins for Claude Code, designed for software developers, DevOps engineers, and technical teams.

What's in this Repository

This repository serves as both:

1. An engineering plugin marketplace - Skills for software development workflows, testing, git operations, CI/CD, and more
2. A development reference - Documentation and examples for creating engineering-specific Claude Code plugins

About Claude Code Skills

Claude Code Skills are modular capabilities that extend Claude's functionality through organized folders containing:

• Instructions (SKILL.md files with YAML frontmatter)
• Scripts and utilities
• Reference materials and templates

Skills are model-invoked (Claude autonomously decides when to use them) rather than user-invoked like slash commands.

Key Benefits for Engineering Teams

• Standardize development workflows across teams
• Automate repetitive engineering tasks
• Enforce code quality and testing standards
• Share engineering expertise via git
• Compose multiple skills for complex engineering workflows
