Neko-233 contributed to the moeru-ai/airi repository by enhancing its internationalization subsystem and improving multilingual documentation. Over two months, Neko-233 standardized ACT JSON escaping and formatting, addressing a parsing issue that previously caused inconsistencies in emotion and action data display across languages. This work, implemented using YAML and Markdown, increased the reliability and maintainability of localized user interfaces. Additionally, Neko-233 refreshed the documentation for LLM API providers, adding new provider recommendations and reorganizing content for clearer onboarding. The updates improved cross-language support and streamlined provider evaluation, demonstrating a focus on quality, maintainability, and future extensibility in both code and documentation.
