WHAT IT DOES

What delete_media_file does on Anki

RISK

Why delete_media_file is rated Critical

The tool name clearly indicates deletion of media files, which is an irreversible operation. While the empty description limits full context, the deletion semantics are unambiguous. High severity reflects the risk of permanent loss of user media assets (images, audio, etc.) in an Anki collection if an AI agent misuses this tool without proper safeguards.

From the tool's definition Tool name is 'delete_media_file' with no description provided. The verb 'delete' indicates irreversible removal of data.

RECOMMENDED RULE

The rule that runs delete_media_file safely

delete_media_file Hidden

delete_media_file is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
