What evidence_delete_attachment does on AbraFlexi
AI agents call evidence_delete_attachment to permanently remove resources in AbraFlexi, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why evidence_delete_attachment is rated Critical
The tool permanently removes an attachment, which cannot be undone. While the blast radius is somewhat limited (one attachment per call), deletion operations are inherently destructive. The presence of other financial tools (bank_transaction_create) on the server raises the risk profile, as a compromised agent could target important financial documents attached to records.
From the tool's definition Tool name contains 'delete' and description states 'Delete an attachment from a record.' This is an irreversible deletion operation.
