overnight-development

Automates software development overnight using Git hooks to enforce test-driven development (TDD). This skill activates when you request "overnight development", "autonomous coding", "work while I sleep", or mention TDD workflows and Git hooks. It leverages Git hooks to block commits until all tests pass, enforcing a rigorous TDD process and ensuring high-quality, production-ready code. Perfect for building features autonomously - just define the goal and let Claude work overnight while tests enforce quality.
