Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the result (the draft EML) without mentioning whether the operation is read-only, what happens if no draft exists, error handling, permissions, or the response format. This is minimal disclosure for a tool with no safety hints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
