📄 Description

Summary

Unifies the subagents and asyncSubAgents params on createDeepAgent into a single subagents array. Previously, sync and async subagents had to be passed separately. Now both go in the same array and are split at runtime using the isAsyncSubAgent type guard, which checks for the presence of graphId. The standalone middleware functions (createSubAgentMiddleware, createAsyncSubAgentMiddleware) are unchanged. This only affects the createDeepAgent convenience API.

Changes

  • Add AnySubAgent type alias (SubAgent | CompiledSubAgent | AsyncSubAgent) and isAsyncSubAgent type guard
  • Widen TSubagents generic bound to readonly AnySubAgent[]
  • Remove asyncSubAgents param from CreateDeepAgentParams
  • Split the unified array at runtime in createDeepAgent, passing sync subagents to createSubAgentMiddleware and async subagents to createAsyncSubAgentMiddleware
  • Export AnySubAgent and isAsyncSubAgent from package index

Example

// Before
createDeepAgent({
  subagents: [syncAgent],
  asyncSubAgents: [asyncAgent],
})

// After
createDeepAgent({
  subagents: [syncAgent, asyncAgent],
})
