UnverifiedValidation tools such as Schema Markup Validator can detect JSON-LD syntax errors and missing required fields, but cannot determine whether the semantics are consistent with visible content, which still requires manual checking.74% similarUnverifiedSchema validation can only guarantee format correctness and cannot determine the security of operations.74% similarUnverifiedStrictly typed Schemas should be used in agent tool definitions, including enum constraints, boundary validation, and returning structured validation errors when parameters are missing or invalid.74% similarUnverifiedOutput validation typically relies on structured validation libraries such as Pydantic to enforce field completeness and type legality checks on model responses before they enter business logic72% similarUnverifiedSchema compliance from any provider only guarantees shape, not semantic correctness; for example, a sign error on an offset row can pass strict JSON-schema validation.71% similar
