Worked on the yumemi-inc/daigirin-2025 repository, focusing on enhancing documentation and asset management to support AI chatbot development. Updated core documentation files, including koty.md and manuscript sections, to align with recent changes and improve consistency across the project. Employed Markdown for technical writing, ensuring that onboarding materials and knowledge transfer resources remained current and accessible. Batch commits were used to streamline documentation improvements, increasing traceability and review efficiency. No runtime features or bug fixes were released during this period, with efforts concentrated on long-term maintainability and developer experience through comprehensive documentation and repository asset updates.
