## Why todoist_complete_task is rated Medium

This tool modifies existing data (task completion status) but does so reversibly—tasks can be unmarked as complete. This is a Write operation rather than Destructive because the action is not permanent and can be undone. The blast radius is low since marking tasks complete affects only task state and workflow tracking, not financial or irreversible data loss.

From the tool's own definition: "Tool 'marks a task as complete' which is a reversible state change to task data. The operation can be undone by marking the task incomplete again, distinguishing it from the irreversible todoist_delete_task."

## Use case

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