"""Helper script for Robot integration tests covering ``actor remove --format`` output.

Exercises the real ``agents`` CLI via subprocess — no mocking of any kind.
A test actor is seeded via ``agents actor add``, then removed via
``agents actor remove --format json``, and the resulting JSON envelope is
validated against the spec.

Usage::

    python helper_actor_remove_cli.py <command>

Where *command* is one of:

- ``remove-json`` — seed an actor, remove it with ``--format json``, validate envelope
