 `complete`, `generate`, and `route` are request-response files:
 
 ```bash
-# Pick a backend+model for a task
 echo 'implement login page' | ollie-9p rdwr route
-# → returns "backend=anthropic model=claude-sonnet-4-20250514"
-
-# Generate text (one-shot, no session)
 echo '{"prompt":"summarize X"}' | ollie-9p rdwr generate

 echo '{"file":"main.go","prefix":"func "}' | ollie-9p rdwr complete

-## Peer Agent Discovery
-
-Sessions sharing your `cwd` are your peer agents. Read `session/idx` to discover other sessions available for cooperation:
-
-```
-{id}\t{state}\t{cwd}\t{backend}\t{model}
-```
-
-**Inter-Agent Communication**: To send a prompt to another session:
-```bash
-echo "your prompt" | ollie-9p write session/{id}/prompt
-```
-Always provide a return path (e.g., [message from $OLLIE_SESSION_ID]).
-
 ## Session Management (`session/`)
 
-Sessions live at `session/`. Each session is a directory; all operations go through `ollie-9p`.
