WHAT IT DOES

What add_tag_to_object does on Sevdesk

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

WHY IT NEEDS A POLICY

Why add_tag_to_object needs a policy

Adding tags is a write operation that modifies object metadata reversibly. It does not read sensitive data in aggregate, does not execute arbitrary code, does not delete data, and does not involve financial transactions. The blast radius is minimal—misuse would only affect organizational tagging/categorization of business objects, not core data integrity or financial state.

From the tool's definition Tool name 'add_tag_to_object' and description 'Add a tag to an object (contact, invoice, etc.)' indicates creating or modifying metadata tags on existing business objects. This is a reversible operation (tags can be removed).
