Persona-Matched Partner Selection

A host agent recruits a teammate at runtime from a pool of candidate agents that differ only in persona description, with capability held equal. In a controlled study across 375 trials, hosts selected partners by task-type stereotype (an open persona for creative work, a conscientious persona for most other categories) and favored complementary personas over self-similar ones, the opposite of human homophily.

whyMultiAgent: The pattern only exists when there is a real pool of distinct candidate agents to choose among, a single agent has no partner to select. Distinct from the already-tracked role-specialization pattern, which assumes personas are assigned upfront by a designer: here the persona-to-role match is discovered endogenously by a host agent choosing among candidates at runtime, and the finding that hosts favor complements over self-similar partners is a property of the selection interaction itself, not of any one agent's internal state.
