# The delegation gate

> No. Delegation must buy isolation or useful parallelism.

## The question

Should every independent task become a subagent?

## The answer

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](/subagents/subagent-isolation) — 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.

<Tip>
  **Design decision:** *Costs:* new context · model calls · coordination · latency · conflicting writes
