Show HN: Pristine – an agent skill that critiques and polishes web UI (github.com)

Pristine is a newly launched agent skill designed to enhance the quality of web user interfaces (UIs) by critiquing and polishing them based on user-centric evaluations. This tool not only assesses UI designs across various dimensions such as aesthetics and usability but also provides actionable feedback and automatic fixes. With compatibility across several platforms like Claude Code, Codex, and GitHub Copilot, Pristine is positioned to streamline web development by integrating improvements seamlessly into existing projects. The significance of Pristine lies in its ability to improve user experience significantly, as demonstrated by its exemplary scoring system. For instance, a UI scored just 3.5/10 was elevated to a remarkable 9.5/10 after applying Pristine. This tool offers a suite of commands, such as /pristine critique which evaluates UIs and suggests specific enhancements. By focusing on both the technical (such as code adjustments) and aesthetic aspects of web design, Pristine empowers developers and designers to create polished, user-friendly interfaces, thereby fostering a more engaging interaction between users and products.
