The question

Should every independent task become a subagent?

​

No. Delegation must buy isolation or useful parallelism.
  • Work item
  • Useful context isolation?
  • Independent + non-conflicting?
  • Delegate
No → main agent · Yes + safe → subagent See “Subagent isolation” — the ~15× multiplier — This gate is why that token multiplier doesn’t apply by default — it’s the price of admission you only pay when isolation or parallelism is actually worth it.
