During October 2025, Michael Harbach refactored the User-Centric API Design Principles documentation in the w3ctag/design-principles repository, focusing on aligning API behavior with user intent. He applied API design principles and technical writing skills to restructure guidance, emphasizing predictability and reducing cognitive load for API consumers. By replacing consent-based prompts with intent-driven documentation, Michael established a documentation-first approach that encourages proactive design decisions. The work, implemented using HTML, improved clarity and consistency across the design principles, supporting both internal alignment and external usability. While the scope was limited to one feature, the depth of the refactor laid groundwork for future enhancements.
