What validation.supersede_duplicate_comparison does on Visionmcp
AI agents use validation.supersede_duplicate_comparison to create or update resources in Visionmcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Visionmcp environment.
Why validation.supersede_duplicate_comparison is rated Medium
The tool supersedes (marks as superseded/replaces) a duplicate comparison entry, which is a reversible write/update operation. Critically, it explicitly does NOT delete history, ruling out Destructive. It modifies the state of a record, making Write the appropriate category. Blast radius is low since it only affects duplicate comparison records and history is preserved.
