Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden. 'Reconcile' implies state mutation and possible side effects on drones, but the description never states whether it writes changes, is idempotent, requires authorization, or what happens to mismatched tasks.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
