In April 2025, Miku enhanced the Order Processing documentation for the stapi-spec/stapi-spec repository, focusing on improving clarity and structure to support developer onboarding and integration. Using Markdown and leveraging strong documentation skills, Miku reorganized the README, introduced new status codes for failure scenarios, and clarified the use of order_parameters. The work included refining navigation and cross-linking within the documentation, making it easier for API consumers to find relevant information. By recording changes across multiple commits, Miku improved traceability and laid the foundation for reduced support requests and faster feature delivery, addressing both technical accuracy and user experience.
