body_fat_calculator stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect SmartTools, apply this rule, and every body_fat_calculator call is checked against it from then on.
