Delete a workspace relation definition.
AI agents call delete_work_item_relation_definition to permanently remove resources in Plane — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs an irreversible deletion operation on workspace metadata (relation definitions). Deletion of structural definitions could break dependent work items or automations across the workspace, affecting multiple users and projects. This is a destructive action that cannot be undone without manual restoration, warranting the Destructive category and high severity.
From the tool's definition Tool name contains 'delete'; description states 'Delete a workspace relation definition' — this irreversibly removes a structural relationship definition from the workspace.

delete_work_item_relation_definition is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_work_item_relation_definition rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
