Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral disclosure. It states the tool deletes a comment and that the index starts at 1, but does not mention whether deletion is permanent, requires specific permissions, or what happens if the index is invalid. With no annotations, a detailed behavioral description would be expected, but these details are missing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
