AI agents call delete-category-group to permanently remove resources in Actual — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a category group from the Actual Budget system. Deletion is an irreversible operation that cannot be undone, fitting the Destructive category. The severity is high because deleting a category group could affect multiple transactions and budget organization, disrupting financial tracking and reporting. Confidence is high due to explicit 'delete' language in both name and description.
From the tool's definition Tool name is 'delete-category-group' and description states 'Delete a category group' — uses the verb 'delete' which is irreversible.
