WHAT IT DOES

What update_project does on Redmine

AI agents use update_project 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 update_project needs a policy

This tool modifies project configuration or metadata reversibly. While it affects a project resource, the operation is non-destructive and can be undone or corrected through subsequent updates. The severity is medium rather than low because projects are typically organizational entities that multiple users depend on; erroneous updates could disrupt team workflows, though the impact is recoverable.

From the tool's definition Tool name 'update_project' and description 'Update an existing project' indicate modification of existing data without deletion or irreversible destruction.
