# Subagents

> Watch nested agent work in read-only tabs when Mythex splits a complex task.

# Subagents

For complex tasks, the Mythex agent may spawn **nested agent runs** (subagents) to investigate or implement in parallel.

## What you see

* A **subagent tab** can open above the chat when nested work is active
* The tab shows that run’s transcript
* Subagent tabs are **read-only** — you do not type into them

## What you control

You **cannot** manually start a subagent. The main agent decides when to use them. You steer the parent chat as usual (Build / Plan / Ask, Stop, follow-ups).

Close a subagent tab with **×** when you are done watching; the main thread and project files stay.
