Moved from prompt-based output validation to schema-enforced execution — the reliability numbers are significant

A Reddit user tested Claude structured outputs and reported 90–95%+ first-pass parse rates with tool_use, typed schemas, enum constraints, and stepwise validation, versus 65–70% for prompt instructions followed by regex or JSON parsing and retries.

Why it matters: HKR-H/K/R all pass: the post has a clear reliability contrast and concrete 90–95%+ vs 65–70% numbers. Source authority is limited to one Reddit experiment, with sample and task details not disclosed, so it stays at low featured.
