## Why add_trip_item is rated Medium

This tool creates or modifies trip data by appending items to a user's saved trip. It is reversible (items can be removed) and has no financial implications by itself, though it operates in a booking/travel context. The moderate blast radius reflects that misconfigured additions could clutter or confuse a user's trip planning, but the operation is not destructive, not immediately financial, and not code execution.

From the tool's own definition: "Tool description states 'Add an item...to a saved trip', which is a create/modify operation that adds data to an existing travel itinerary."

## Use case

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