WHAT IT DOES

What create_activity_code does on Smokeball

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

WHY IT NEEDS A POLICY

Why create_activity_code needs a policy

The tool creates a new billing activity code, a reversible write operation that modifies the law firm's billing configuration. This is Write rather than Execute because it creates a discrete billing entity rather than triggering external operations.

From the tool's definition Tool name 'create_activity_code' indicates creation of a new billing activity code. Description states 'Create a billing activity code,' which is a data creation operation.
