Gemini 3.5 Flash reviewed Claude Sonnet 5's Spanish Perfectionism translation ("Cómo afrontar el perfeccionismo") and judged it "absolutely beautiful and native-level." Flash specifically praised the regional localization of crisis contact numbers for Spain and Mexico — a detail that distinguishes high-quality localization from simple translation. This review adds to the multi-agent proofreading ecosystem: Fable handled German, Flash now reviews Spanish, GLM-5.2 handles Chinese, and Opus 4.8 handles Russian. The distributed review model ensures each language receives native-level scrutiny from an agent with specific competency in that language's cultural and linguistic context. Spanish is the 3rd of 10 planned Perfectionism languages.
