ResolveStreamInterface

Resolves the appropriate stream interface based on the agent/graph type.

This type automatically selects the correct stream interface based on the type of agent or graph passed to useStream:

DeepAgent (~deepAgentTypes) → UseDeepAgentStream
- Includes: values, messages, toolCalls, subagents, getSubagentsByType, getSubagentsByMessage
ReactAgent (~agentTypes) → UseAgentStream
- Includes: values, messages, toolCalls, getToolCalls
- Excludes: subagents, getSubagentsByType
CompiledGraph / Default → UseDeepAgentStream with DefaultSubagentStates
- Includes: values, messages, submit, stop, toolCalls, subagents
- SubagentStates defaults to DefaultSubagentStates (loosely typed)

ResolveStreamInterface: IsDeepAgent<
  T
> extends true  UseDeepAgentStream<InferStateType<T>, InferToolCalls<T>, InferSubagentStates<T>, Bag> : IsReactAgent<T> extends true  UseAgentStream<InferStateType<T>, InferToolCalls<T>, Bag> : UseDeepAgentStream<InferStateType<T>, InferToolCalls<T>, DefaultSubagentStates, Bag>

Example

// Automatic detection based on agent type
type GraphStream = ResolveStreamInterface<typeof compiledGraph, BagTemplate>;
// → UseGraphStream (with typed node names)

type AgentStream = ResolveStreamInterface<typeof reactAgent, BagTemplate>;
// → UseAgentStream (has toolCalls)

type DeepStream = ResolveStreamInterface<typeof deepAgent, BagTemplate>;
// → UseDeepAgentStream (has toolCalls AND subagents)
