RISK

Why create_appointment is rated Medium

This tool creates a new appointment record in GoHighLevel, which is a reversible write operation. It does not execute arbitrary code, delete data, or move money. The appointment can be modified or canceled later. The medium severity reflects that creating bogus appointments could disrupt scheduling and customer service operations, but the impact is localized and reversible.

From the tool's definition Tool name 'create_appointment' and description 'Create a new appointment/booking in GoHighLevel' indicate the tool creates/adds new data to the system reversibly.

RECOMMENDED RULE

The rule that runs create_appointment safely

create_appointment Rate-limited

create_appointment stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
