During April 2025, Yasuda focused on enhancing developer experience for the kintone/js-sdk repository by delivering comprehensive documentation improvements for the @kintone/rest package. Yasuda revised the README in Markdown to clarify the package description, highlight its experimental status, and provide clearer installation and usage examples. Additionally, Yasuda authored a detailed migration guide to assist developers transitioning from @kintone/rest-api-client, covering client creation, authentication, timeouts, and advanced configurations such as proxy and HTTPS agent setup. The work emphasized technical writing and documentation skills, ensuring developers have accurate expectations and streamlined onboarding, while explicitly noting unsupported features in the new client.
