AI agents call list_note_comments to retrieve information from Filevine without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing comment data associated with a note in the Filevine legal case management system. It performs no modifications, deletions, or external actions—purely a read operation on existing data. The blast radius of misuse is minimal, as it only exposes information already stored in the system.
From the tool's definition Tool name 'list_note_comments' and description 'List all comments on a note' indicate a retrieval operation with no side effects.
