What update_offer does on Keycrm

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

WHY IT NEEDS A POLICY

Why update_offer needs a policy

This tool creates or modifies data in a reversible manner (update operation on product variants), which fits the Write category. Severity is medium because unintended modifications to product variants could impact catalog consistency, pricing, or inventory accuracy, but changes are reversible via subsequent updates. Confidence is high given the clear description of update semantics.

From the tool's definition Tool description explicitly states 'Update fields on one or more existing product variants,' indicating modification of existing data through reversible operations.
