Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing behavioral traits. While it marks the tool as [DESTRUCTIVE] and mentions it deletes 'the backup schedule and archives', it doesn't disclose whether this action is irreversible, what happens to in-progress backups, whether it requires specific permissions, or what the response looks like. The 'confirm' parameter in the schema hints that confirmation is needed, but the description doesn't explain that it must be set to true to proceed. The contradiction flag is false because there are no annotations to contradict.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
