WHAT IT DOES

What roam_add_todo does on Roam Research

AI agents use roam_add_todo 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.

RISK

Why roam_add_todo is rated Medium

This tool creates new todo blocks, which modifies the user's knowledge base reversibly. While not destructive (todos can be deleted or modified), it does write new data to the system. The blast radius is medium because malicious use could spam the graph with unwanted todos, but the impact is limited to non-critical data and is easily reversible.

From the tool's definition Tool name 'roam_add_todo' and description 'Add a list of todo items as individual blocks to today' indicate creation of new data blocks in the Roam Research graph.
