Miguel Arcilla contributed to the MicrosoftDocs/m365copilot-docs repository by enhancing the Microsoft 365 Agents SDK documentation. He focused on improving the clarity and accuracy of the overview-custom-engine-agent.md file, addressing a typo and refining explanations of the SDK’s capabilities and use cases. Using Markdown and leveraging his skills in documentation and technical writing, Miguel’s update aimed to reduce ambiguity and streamline developer onboarding. His work emphasized documentation hygiene, with precise commit messaging and traceability through a clear git hash. While the scope was limited to a single bug fix, the update improved the overall quality and maintainability of the documentation.
