`b/q` reads its prompt from args or stdin — not both. When args are present, stdin is `b/q` and `b/job` write to stdout and compose naturally with Unix pipes. When both args
ignored. This shapes how pipelines compose: and stdin are present, args are treated as the instruction and stdin as the content:
```sh ```sh

# pipe b/q output through shell tools, then into another b/q via stdin
