AI agents use ebay_suppress_violation to create or update resources in Ebay — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ebay environment.
Suppressing a listing violation modifies the state of a compliance/enforcement record on eBay, effectively hiding or dismissing a violation. This is a reversible write action (violations could potentially be unsuppressed), but carries high severity because misuse could allow non-compliant listings to remain active, circumventing marketplace policy enforcement.
