Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of signaling behavior. 'Report' implies a read-only operation with no side effects, which is useful, but the description does not disclose how transitive links are computed, what the bundle parameter affects, or any permissions or performance considerations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
