## Why update_appointment is rated Medium

The tool creates or modifies data reversibly—updating an appointment can be undone by changing it again. This is a Write operation, not Destructive (appointments aren't deleted, merely modified). The medium severity reflects that incorrect appointment updates could disrupt scheduling, notifications, or business operations, but the effect is contained to individual appointments and reversible.

From the tool's own definition: "Tool name 'update_appointment' with description 'Update an existing appointment in GoHighLevel' indicates modification of existing data (appointment records)."

## Use case

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