Show diff of pending changes
AI agents call diff_pending_changes 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 pending changes (likely a diff view) with no side effects. It does not create, modify, delete, execute, or move data—it only reads and presents comparison information about changes staged for later application. This is a classic Read operation with minimal risk.
From the tool's definition Tool name 'diff_pending_changes' and description 'Show diff of pending changes' indicate retrieval and display of pending modifications without applying them or altering any state.
