Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=false and readOnlyHint=false, so the agent knows writes are not destructive. The description usefully clarifies that the output is a draft for review rather than a live mutation, but adds nothing about permissions, the review/approval flow, or rate/repeat behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
