Cobalt — Type rules

To enforce TypeScript return type annotations in a monorepo, apply standardized coding rules that define when to explicitly annotate exported functions versus relying on TypeScript inference for internal helpers.

You should use Zod schema inference over manual interfaces for API type safety to enforce schema-first development, preventing drift between runtime validation logic and static type definitions.

Standardize TypeScript conventions for server-side logic by applying project-specific rules for function signatures, return type annotations, and generic usage to ensure consistency across database interactions and API schemas.

You should allow Drizzle row inference instead of explicit return types when refactoring helper functions, relying on inference to maintain clean and maintainable code where explicit annotations are unnecessary.

Yes, this Skill works with Zod and Drizzle for TypeScript refactoring by applying type-safety patterns that standardize schema inference and database row typing within the Cobalt monorepo.
