AI agents call snow_get_attachments to retrieve information from Serac without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves/lists attachment metadata from a ServiceNow record without altering, deleting, or executing any operations. It is a straightforward query operation that returns data, fitting the Read category. Severity is low because reading attachments poses minimal risk unless they contain highly sensitive data, but the operation itself is non-destructive and read-only.
From the tool's definition Tool name 'snow_get_attachments' and description 'List all attachments on a single record' indicates a retrieval operation with no modification or deletion.
