## Why despezzas_prepare_update_transaction is rated Medium

The 'prepare' prefix suggests this tool stages or constructs an update operation on transactions without immediately executing it—a reversible write action. However, the empty description creates uncertainty about whether this is truly a preparatory step (Write) or if it actually commits changes (potentially Destructive if it overwrites transaction data).

From the tool's own definition: "Tool name contains 'prepare_update_transaction'; part of Despezzas financial system alongside creation and update operations (despezzas_batch_update_transactions, despezzas_create_transaction)."

## Use case

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