Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full disclosure burden. It states that an outdated addon triggers update instructions, tells the user to restart/re-enable, and explains that telemetry_consent can be on, off, or null if Blender cannot be reached. It stops short of labeling the operation as read-only, but the wording implies a check with no mutation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
