Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate this is not read-only (readOnlyHint=false) so mutation is expected. The description adds context about the purpose (locking for editing and visibility to other agents), but does not disclose additional behavioral details like lock reversal, duration parameters, or side effects on concurrent access. Some value is added, but it is not extensive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
