Developed and delivered the Farcaster Manifest Schema Validation and Dedup Utility for the farcasterxyz/miniapps repository, focusing on improving manifest schema typing and validation for requiredChains and requiredCapabilities fields. The work introduced a deduplication utility that systematically removes duplicate entries from manifest lists, ensuring cleaner and more reliable schema definitions. TypeScript was used to update type definitions, enabling more accurate inference of capabilities from the defined list and enhancing type safety for developers. The changes were scoped to a single feature, with no major bugs reported, and demonstrated a methodical approach to schema validation, type definitions, and data integrity using TypeScript.
