Delete a folder from a project. WARNING: This also deletes all test cases in the folder.
AI agents call testmo_delete_folder to permanently remove resources in Testmo — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently removes folders and all nested test cases without the ability to undo the operation. This is a destructive action that cannot be reversed, placing it in the Destructive category. The severity is high because deletion of entire folders with cascading deletion of all contained test cases represents significant data loss, though the blast radius depends on folder size and criticality.
From the tool's definition Tool name includes 'delete'; description states 'Delete a folder from a project' and explicitly warns 'This also deletes all test cases in the folder.' This is irreversible data destruction.
