Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of disclosing behavior. It states that the tool creates a report and returns its ID, which is useful. However, it does not disclose whether the operation is asynchronous, requires specific permissions, or has side effects on existing reports. This is minimal but not misleading.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
