Worked on the MicrosoftDocs/m365copilot-docs repository to clarify agent response modes within Microsoft 365 Copilot documentation. Focused on improving documentation quality by removing unsupported UX warnings and adding a known-issues note regarding default response mode behavior when invoked via @mention. Employed Markdown and technical writing skills to enhance clarity and reduce ambiguity for developers integrating agent features. No major bugs were addressed during this period, as the primary emphasis was on documentation accuracy and maintainability. The updates established a clearer foundation for future UX alignment, supporting both developer experience and user support through more consistent and transparent technical documentation practices.
