List backup transactions
AI agents call list_backups to retrieve information from RPG Maker MV Content Bridge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about existing backups without modifying, deleting, or executing any operations. It is a read-only query that presents historical backup data to the user. The blast radius of misuse is minimal—an AI agent querying backups cannot damage the project or cause unintended side effects beyond information disclosure.
From the tool's definition Tool name 'list_backups' and description 'List backup transactions' indicate a retrieval operation with no side effects. The verb 'list' is a pure query operation.
