Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states the tool exports a book but doesn't disclose behavioral traits such as whether it's a read-only operation, what the output looks like (e.g., file download link, raw content), potential side effects (e.g., generating server load), or any authentication/rate limits. The description is minimal and lacks operational context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
