Moca Tribe Sorter

This tool assigns a Moca Tribe (Angel, Builder, Dreamer) to a user based on their stated goals and optional wallet history. It accepts userIntent as required natural language text describing goals, playstyle, or onboarding answers, and onChainHistory as an optional JSON string summarizing wallet age, holdings, and interaction history. The worker must transform these inputs into a tribe classification with confidence and reasoning, and output only JSON that strictly validates against the system-provided structured output schema.
