WHAT IT DOES

What background_remove does on Jgkme/kilo Image Gen

AI agents use background_remove to create or update resources in Jgkme/kilo Image Gen — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Jgkme/kilo Image Gen environment.

WHY IT NEEDS A POLICY

Why background_remove needs a policy

This tool modifies an image by removing its background and outputting a new PNG. It is a reversible write/transform operation (the original image is not destroyed, a new processed file is created). It does not execute arbitrary code, delete data irreversibly, or involve financial transactions.

From the tool's definition Remove the background from an image... preserve transparency in the PNG output

What risk level is background_remove? +

background_remove is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit background_remove? +

Yes. Add a rate_limit block to the background_remove rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
