Unused and cleanup
Find orphaned and unreferenced metadata and superseded OmniStudio versions, split by confidence so you remove the right things safely.

Cleanup candidates
Orphaned components with no links either way, items nothing depends on, and inactive OmniStudio versions. Source-only, so confirm in the org before removing: dynamic references and reports are not visible here.
Destructive changes
Generate a destructiveChanges manifest to remove confirmed candidates through your normal deployment flow.
