WHAT IT DOES

What create_entity_draft does on RPG Maker MV Content Bridge

AI agents use create_entity_draft to create or update resources in RPG Maker MV Content Bridge — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your RPG Maker MV Content Bridge environment.

WHY IT NEEDS A POLICY

Why create_entity_draft needs a policy

This tool creates new entities within the RPG Maker project but operates in a 'draft' mode, implying changes are not immediately committed and can be discarded via 'discard_pending_changes'. The write is reversible and has no destructive or financial impact. Severity is medium because uncontrolled entity creation could clutter the project, but the draft mechanism and context of 'safe' writes mitigate risk.

From the tool's definition Tool name 'create_entity_draft' combined with description 'Draft a new entity' and server context 'safely write content into an RPG Maker MV project' indicates this creates new game entities (items, skills, events, etc.) in a reversible draft state.
