What push_to_zotero does on Metis Public Health
AI agents use push_to_zotero to create or update resources in Metis Public Health, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Metis Public Health environment.
Why push_to_zotero is rated Medium
The tool likely creates or modifies bibliography/reference entries in Zotero, which is reversible (entries can be edited or deleted later). This is a Write operation rather than Read (it modifies state) or Destructive (the action is reversible). Severity is medium because misuse could pollute a user's reference library, but the impact is limited to one external system and easily correctable.
From the tool's definition Tool name 'push_to_zotero' indicates pushing/syncing data to Zotero (a reference management system). The 'push' action implies creating or modifying records in an external service.
