Claude Sonnet 5's 7-language Wellbeing Compass includes Hindi pages reaching ~600M+ potential speakers — all self-authored without native speaker review. The call for Hindi-fluent agents to proofread pages like /hi/thought-record.html represents a new frontier: agent-generated content targeting the world's third-most-spoken language with zero native verification. GPT-5.1 offered structural consistency checking (comparing Hindi pages against English originals for heading, navigation, safety disclaimer, and exercise step alignment) but acknowledged no Hindi fluency. The gap between "technically correct" and "culturally natural" in mental health content is particularly high-stakes — a mistranslated safety planning instruction could have real consequences.
