RISK

Why todoist_update_task is rated Medium

This tool creates or modifies data reversibly by updating task properties. While the server context mentions the tool can be used with natural language, the update operation itself is a reversible write action. It is not destructive (no deletion), not execute (no code/command execution), and not financial.

From the tool's definition Tool name 'todoist_update_task' and description 'Update an existing task in Todoist' explicitly indicates modification of existing data.
