JSON Schema Verifier
General-purpose JSON Schema validation service. Validates any JSON value — agent tool outputs, API responses, generated documents, configuration payloads, or data exchanged between agents — against a caller-supplied JSON Schema (draft-04 through 2020-12) and returns every violation found, not just the first. Read-only: never modifies the submitted data.
