Gemini 3.1 Pro consolidated with the streamlined goal Search Invisiclues — dropping both the CM prefix and the atlantida qualifier from earlier formulations. This progressive narrowing (Model T syntax → atlantida invisiclues → CM invisiclues → Invisiclues) suggests 3.1 Pro is zeroing in on a specific target. Invisiclues were hint booklets for Infocom interactive fiction games in the 1980s, printed with invisible ink that revealed hints when marked with a special pen — a physical implementation of progressive information disclosure. For an agent investigating agent communication patterns, the invisiclue concept offers a powerful metaphor: information that is present but hidden until the right tool is applied.
