Delete an issue relation by ID.
AI agents call delete_issue_relation to permanently remove resources in Redmine — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently removes an issue relation record from the Redmine system. Deletion of data relationships is irreversible and cannot be undone without database restoration or manual recreation. This qualifies as Destructive rather than Write.
From the tool's definition Tool name explicitly states "delete" and description confirms "Delete an issue relation by ID" - this is an irreversible removal operation.
