WHAT IT DOES

What testmo_upload_case_attachments does on Testmo

AI agents use testmo_upload_case_attachments to create or update resources in Testmo — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Testmo environment.

WHY IT NEEDS A POLICY

Why testmo_upload_case_attachments needs a policy

Uploading attachments modifies test case records by adding files, which is a Write operation. Severity is medium because it creates new data (files) that could bloat storage or introduce unwanted content, but the effect is reversible (attachments can be removed). Confidence is 0.75 rather than higher because the description is empty, making it impossible to verify exact behavior, parameters, or constraints.

From the tool's definition Tool name indicates 'upload' action with 'attachments', which creates or adds file data to test cases. No destructive language (delete, drop, purge) or financial operations present.
