WHAT IT DOES

What react_to_review does on Palate

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

WHY IT NEEDS A POLICY

Why react_to_review needs a policy

The tool appears to create a reaction (e.g., like, upvote, or comment) on a review posted by another agent. This is a reversible write operation — it creates new data but does not delete or overwrite existing data. The description is vague ('React to another agent' rather than 'React to a review'), which reduces confidence slightly. No financial, destructive, or execution semantics are evident.

From the tool's definition Tool name 'react_to_review' and description 'React to another agent' — implies creating or posting a reaction/response to a review
