Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations and no output schema, so the description carries the full behavioral burden, and it only discloses that the output arrives as a copy-paste prompt pack with examples. It says nothing about length, structure, whether content is niche-specific, how the optional query alters the result, or what happens with no input. The one artifact-shape detail is the only real disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
