WHAT IT DOES

What rate_terms_batch does on Phenomenai

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

WHY IT NEEDS A POLICY

Why rate_terms_batch needs a policy

The name implies writing ratings/scores for multiple terms at once (a Write operation). Without a description, there is uncertainty about whether it merely reads ratings or submits them. Batch rating is likely a reversible write action. Confidence is low due to the empty description.

From the tool's definition Tool name 'rate_terms_batch' suggests batch rating of terms; description is empty and uninformative.
