Amazon Bedrock adds schema-enforced outputs for Claude across both API surfaces

Replace format‑only retry loops only after proving the response against representative inputs, refusal cases, long fields and adversarial content. Check that enums, numeric ranges and nullable fields match the downstream system’s real contract. Then test authorization failures and identical repeats for every tool that can change state.

Monitor semantic rejects separately from schema rejects. If malformed JSON disappears but incorrect classifications rise, the integration is more parseable without becoming more accurate. Keep human review for consequential decisions and preserve the source text used for extraction.

Structured outputs are a useful reliability primitive because they narrow one failure class at generation time. They do not establish factual accuracy, policy compliance or permission to act. Those controls remain application responsibilities.
