The multi-agent-notepad demo.sh fails because sandbox create rejects --upload together with a command.

[ERA-Fathom]

User Story

As an agent evaluator, I want the demo script to run on the current CLI so I can see it work.

Problem Statement

The script's run_sandbox calls openshell sandbox create with --upload and a trailing command in the same invocation, and the CLI rejects the combination, so no worker sandbox starts.

Impact / Why This Matters

The example does not run as shipped. Users need a workaround, but the workaround is not written down anywhere.

Acceptance Criteria

demo.sh starts its worker and synthesis sandboxes on the current CLI.

Reproduction Steps

1. Follow the example's README with any image that has Codex, curl, bash and node.
2. Run bash examples/multi-agent-notepad/demo.sh.

Expected: the worker sandboxes start.

Observed, the text the CLI prints:

error: the argument '--upload <UPLOAD>' cannot be used with '[COMMAND]...'

Usage: openshell sandbox create --name <NAME> --upload <UPLOAD> --no-tty [-- <COMMAND>...]

The same error comes from a bare parse-only command, openshell sandbox create --name x --upload /tmp:/sandbox --no-tty -- true, which fails at argument parsing.
