Beta Managed Agents Multiagent Params

• BetaManagedAgentsMultiagentParams object

  A coordinator topology: the session's primary thread orchestrates work by spawning session threads, each running an agent drawn from the agents roster.

  • type: "coordinator"

  • agents: array of BetaManagedAgentsMultiagentRosterEntryParams

    Agents the coordinator may spawn as session threads. 1–20 entries. Each entry is an agent ID string, a versioned \{"type":"agent","id","version"\} reference, or \{"type":"self"\} to allow recursive self-invocation. Entries must reference distinct agents (after resolving self and string forms); at most one self. Referenced agents must exist, must not be archived, and must not themselves have multiagent set (depth limit 1).
