Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It only states that the tool returns a citation with timestamps and evidence, but does not disclose whether it is read-only, any prerequisites (e.g., insight must exist), potential side effects, or response format. This is insufficient for a safe and correct invocation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
