During December 2025, Sang updated the Vehicle Door Status API documentation in the autowarefoundation/autoware-documentation repository, focusing on aligning the topic and message type with recent API changes. Using Markdown and leveraging skills in API design and technical writing, Sang refactored the doorstatus topic and type to ensure consistency and clarity for developers integrating vehicle components. The work emphasized maintainability and traceability, with clear commit history and signed-off changes. By improving the documentation structure, Sang reduced integration risks and streamlined onboarding for new developers, ultimately supporting faster adoption and fewer support escalations across teams working with vehicle interface data.
