Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description merely restates the action, adding no behavioral context beyond what annotations already provide (readOnlyHint=false, destructiveHint=false). It does not mention that comments are appended, required permissions, or behavior on duplicate comments. The description fails to add value.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
