Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations only declare readOnlyHint=false and destructiveHint=false, so the write nature is already implied. The description adds real context beyond that: an auth requirement (valid token in ESG_HUB_WRITE_TOKEN), the human-review gate, and the returned proposal ID/status.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
