Worked on the Credal-ai/actions-sdk repository to enhance Google Sheets integration by developing a new action for retrieving spreadsheet metadata, such as titles and sheet identifiers, without downloading cell data. This approach improved discoverability and efficiency for agent-driven workflows. Refactored the export process to prioritize XLSX format, establishing a robust fallback chain for cross-format compatibility and performance. Centralized shared workbook parsing logic into a utility to reduce code duplication and standardized metadata handling across Google Sheets, XLSX, and CSV formats. Utilized TypeScript and full stack development skills, with a focus on API development and the Google Sheets API throughout the project.
