Worked on the microsoft/graphrag repository to address a critical issue in the Auto Prompt Tuning command-line interface. Focused on improving documentation and user experience, the developer corrected a parameter typo by replacing --no-entity-types with --no-discover-entity-types, ensuring the CLI accurately disables entity type discovery as intended. This change aligned the codebase with its Markdown documentation, reducing confusion for users conducting prompt-tuning experiments. The update was tracked through a dedicated pull request and commit, demonstrating attention to traceability and workflow consistency. The work primarily involved documentation skills and proficiency with Markdown, emphasizing careful maintenance of developer-facing tools and resources.
