Worked on the traPtitech/traQ repository to enhance API documentation by clarifying how image and icon pixel limits are defined, configured, and enforced. Focused on specifying the role of Config.MaxPixels, including its default value and the precise configuration path for image uploads, to reduce ambiguity for developers integrating with the API. Utilized YAML for documentation updates and applied best practices in API documentation and configuration-driven guidance. The improvements aimed to decrease the risk of misconfiguration, streamline onboarding, and ensure stable image upload behavior, with careful attention to documentation hygiene and commit traceability throughout the development process. No bugs were fixed.
