Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden. It reveals the action of adjusting confidence and the conditional manual review queue, adding context beyond the verb. However, it does not disclose whether the operation is a write, if it is reversible, return format, or error handling, leaving notable gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
