Subagent collaboration: parallel work patterns

The main agent spawns up to 4 concurrent subagents; depth ≤ 2 — balanced parallelism without runaway recursion.

Kition Team·Feb 20, 2026·7 min read

Three patterns

  • Map: batch (10 drafts, each subagent handles one)
  • Multi-perspective: review (one subagent checks facts, one tone, one SEO)
  • Research: divergent search (5 query different sources, main agent synthesizes)

Tool semantics

  • spawn_agent: dispatch
  • send_input / send_message: communicate
  • wait_agent: await result
  • close_agent: tear down
  • list_agents: who is running
  • resume_agent: pick up a paused one
