What the agent is told

The description the model reads when deciding whether to call this. It is the only thing that decides whether the tool fires at the right moment, so it is worth knowing what it says.

cancel_registration

Cancel one of the signed-in viewer’s session registrations by its registration id (from my_registrations). Requires the viewer to be signed in.
