Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate destructiveHint=true and readOnlyHint=false, so the safety profile is partly covered by structured data. The description adds the 'using LTspice' context but does not explain what may be destroyed (e.g., overwriting an existing .net file) or what side effects occur.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
