 ## Subagents
 
-Subagents are ordinary Ollie sessions. When you call `subagent_spawn`, it creates a new session under `/b/` — a short-lived job session — runs the prompt, collects the result, and cleans up. There is no architectural difference between a subagent and any other session you could spawn manually via `${OLLIE}/s/new`; `subagent_spawn` is simply a convenience wrapper that handles lifecycle and result collection for you. Use it when you want to delegate work and get a result back in the same turn. Use `${OLLIE}/s/new` directly when you want a persistent peer session.
