Worked on the zapier/zapier-platform repository to refactor and consolidate TypeScript input field type definitions, focusing on improving data integrity and maintainability for complex form scenarios. The approach centered on strengthening type safety by updating parent field contributions and line item structures, as well as enhancing input validation for both required and optional fields. Utilized TypeScript features such as type definitions, type testing, and utility types to simplify and stabilize complex input types. Improved test assertions and added expectType checks to catch mismatches early, resulting in more reliable input handling and laying groundwork for safer downstream integrations and data modeling.
