Unclear It is not clear which command this is or whether it is available to everyone.

What

A command that runs case files, and that also has a --scaffold option, gains --disallow-tools <tools...>. It names built-in tools to keep from Claude in every case, even if they are granted, for example Agent TaskStop.

Why

People running evaluations can block certain tools for a whole run without editing each case.
