WHAT IT DOES

What create_version does on Redmine

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

WHY IT NEEDS A POLICY

Why create_version needs a policy

This tool creates a new project version in Redmine, which is a reversible write operation. It adds metadata to a project (version records) but does not execute arbitrary code, delete data, or commit financial transactions. The blast radius is moderate—creating unintended versions could clutter project management but can be undone by deletion.

From the tool's definition Tool name is 'create_version' and description states 'Create a new version for a project.' The verb 'create' and action of adding a new version indicates data creation/modification.
