Delete a local terminal watch rule by ID.
AI agents call delete_watch_rule to permanently remove resources in Todos — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs a delete operation that cannot be undone. Deletion of watch rules is irreversible and permanently removes monitoring configurations. While the blast radius is somewhat contained (affects only local watch rules rather than critical data), the destructive nature and permanence of deletion places this in the Destructive category rather than Write.
From the tool's definition Tool name is 'delete_watch_rule' with action verb 'delete'; description states 'Delete a local terminal watch rule by ID', confirming irreversible removal of a watch rule configuration.
