Yellhorn streamlines software development workflows by combining AI-driven workplan generation with automated code review. By leveraging the power of Gemini and OpenAI models, Yellhorn creates detailed implementation plans as GitHub issues, providing coding agents like Claude Code with comprehensive context. It also facilitates code diff evaluation against these plans, ensuring implementations align with original requirements and offering feedback for necessary adjustments. Through seamless GitHub integration and flexible context control using `.yellhornignore` files, Yellhorn empowers developers to improve code quality and maintain project consistency.
