## Why update_relationship is rated Medium

The tool modifies relationship data reversibly (update operations can be undone or corrected). The empty description reduces confidence slightly, but the naming pattern and context of sibling CRUD tools clearly indicate a Write operation.

From the tool's own definition: "Tool name 'update_relationship' combined with sibling tools including 'create_relationship', 'delete_relationship', and 'delete_entity' suggests CRUD operations on relationship data. The 'update_' prefix indicates modification of existing data."

## Use case

AI agents use update_relationship to create or update resources in Optimized Memory MCP Server V2, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Optimized Memory MCP Server V2 environment.
