Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description should disclose behavioral traits, but it only mentions billing credits. It does not state whether the operation is read-only, requires authentication, handles errors, or has rate limits. This is a critical omission for a tool that takes a sensitive auth_token.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
