Type Safety
Catching bad data early
Using types, schemas, or validators so invalid data fails at edit or parse time instead of in production. TypeScript, Zod, and SQL constraints are all forms of type safety.
Concrete example
A typed function that requires a `UserId` will not silently accept a random string.
Why it matters
One of the highest-leverage ways to make agent-written code trustworthy.
