## Why roam_move_block is rated Medium

This tool modifies existing data by relocating blocks within the Roam Research graph—a reversible write operation. While not destructive (the block still exists, just repositioned), it represents a Write category action as it alters the organizational structure of the user's knowledge base.

From the tool's own definition: "Tool description states 'Move a block to a new location (different parent or position)' which modifies the structure and location of data within the graph. The verb 'move' indicates a write operation that changes data state."

## Use case

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