WHAT IT DOES

What add_task_dependency does on Helios-9 MCP Server

WHY IT NEEDS A POLICY

Why add_task_dependency needs a policy

This tool creates a new relationship record (dependency) between tasks, which is a reversible modification operation. It does not execute arbitrary code, delete data, or have financial implications. The blast radius is limited to task metadata/relationships within the project management system. Severity is low because task dependency errors can be corrected by removing the relationship.

From the tool's definition Tool name is 'add_task_dependency' and description states it will 'Add a dependency relationship between tasks' - this creates/modifies a relational link between existing tasks without deleting or destroying data.
