WHAT IT DOES

What link_parent_work_item does on Azure Devops

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

WHY IT NEEDS A POLICY

Why link_parent_work_item needs a policy

This tool creates a parent-child relationship between two work items in Azure DevOps. It modifies existing work item data by setting a hierarchical link, which is a reversible write operation. It does not delete data or execute code, making Write the most appropriate category. Misuse could reorganize work item hierarchies incorrectly, but the blast radius is limited to project structure.

From the tool's definition 建立 Work Item 父子關聯（將 childId 設定 parentId 為父項）— 'establishes parent-child relationship', i.e., creates/modifies a link between work items
