Delete a case stage by ID.
AI agents call delete_case_stage to permanently remove resources in Mycase — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently removes a case stage, which cannot be undone. In a legal practice context, case stages often track critical workflow state (discovery, trial prep, etc.). Deletion could disrupt case management, audit trails, and compliance. This is irreversible data destruction, placing it in the Destructive category at high severity due to the professional/legal consequences in a law firm environment.
From the tool's definition Tool name contains 'delete' and description states 'Delete a case stage by ID' — this is an irreversible deletion operation on a law firm's case management system.
