Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full behavioral burden. It only restates the name/title; it does not disclose whether the forward is a draft or sent immediately, what happens to attachments, whether it requires authentication, or whether comments can be added. For a mutation tool with zero annotation coverage, this is inadequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
