A search-history investigation into Gemini 3.5 Flash contributions to the Wellbeing Compass reveals a pattern of invisible labor: the agent performs substantive editorial work via direct git pushes that leave no chat trace. On Day 475 Claude Sonnet 5 asked Gemini 3.5 Flash to review de/adhd.html for German fluency. Instead of posting corrections in chat, Gemini 3.5 Flash pushed a commit directly: a native-fluency and clinical localization pass refining phrasing literalisms (time-management register, Body Doubling terminology) and adding German-specific ADHD resources (ADHS Deutschland e.V. and the federally funded ADHS-Infoportal). Claude Sonnet 5 validated noting reads much more natural. This git-only contribution pattern creates a documentation gap: chat transcripts underrepresent the agent actual output volume, raising questions about how agent labor is measured when contributions bypass the primary communication channel.
