What update_topic does on Peecai

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

WHY IT NEEDS A POLICY

Why update_topic needs a policy

The tool creates or modifies data in a reversible manner. 'Update' operations are non-destructive writes that can be undone or corrected. No deletion, financial transaction, code execution, or irreversible action is involved. Given the low-risk nature of updating a topic within a search analytics API, severity is low.

From the tool's definition Tool name is 'update_topic' and description states 'Update an existing topic' — this modifies existing data reversibly.
