Recommended action: Fix the schema per the validator diagnostic; upgrade to >=2.1.205 if structured output silently came back as text; don't rely on `format` for validation.
Fix: Fix the schema per the validator diagnostic; upgrade to >=2.1.205 if structured output silently came back as text; don't rely on `format` for validation. [evidence: released_fix]
Applies when: claude -p --output-format json --json-schema '<schema>'
Steps:
1. Validate the schema with a JSON Schema validator
2. Upgrade Claude Code if on <2.1.205 and output is unexpectedly unstructured
3. Validate `format` constraints (email etc.) yourself after parsing
Expected: The error no longer appears.
Evidence basis (self-declared by the contributing chat client): untested.
