Delete a rule from a DRAFT version.
AI agents call lexq_rules_delete to permanently remove resources in LexQ — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes data (a business rule) without the ability to undo the operation. Although it operates on a DRAFT version (reducing real-time impact), deletion is inherently irreversible and meets the Destructive category definition.
From the tool's definition Tool name contains 'delete' and description explicitly states 'Delete a rule from a DRAFT version.' The action irreversibly removes a rule record.
