WHAT IT DOES

What update_workflow_general does on Xcode Cloud

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

WHY IT NEEDS A POLICY

Why update_workflow_general needs a policy

This tool modifies workflow configuration settings (name, description, build behavior) but does not delete data or execute arbitrary code. It falls under Write category because it creates or modifies data reversibly.

From the tool's definition update_workflow_general updates workflow fields including name, description, and clean build behavior. The word 'update' indicates modification of existing data.
