Discard pending changes
AI agents call discard_pending_changes to permanently remove resources in RPG Maker MV Content Bridge — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Discarding pending changes destroys work that has been drafted but not yet committed. This cannot be undone once executed, making it a Destructive action. The blast radius is high because an AI agent could inadvertently wipe out all staged drafts across the project.
From the tool's definition 'Discard pending changes' — permanently removes all staged/pending modifications that have not yet been applied, which is irreversible.
