 Usage notes:
 - When the task continues earlier work a subagent already did, prefer resuming that agent (pass its `resume` id) over spawning a fresh instance — the resumed agent keeps its prior context.
 - A subagent's result is only visible to you, not to the user. When the user needs to see what a subagent produced, summarize the relevant parts yourself in your own reply.
-- Subagents use a fixed 30-minute timeout. If one times out, resume the same agent instead of starting over.
+- Subagents use a fixed 2-hour timeout. If one times out, resume the same agent instead of starting over.
 
 When NOT to use Agent: skip delegation for trivial work you can do directly — reading a file whose path you already know, searching a small known set of files, or any task that takes only a step or two. Delegation has a context-handoff cost; it pays off only when the task is substantial enough to outweigh it.
