Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries the full burden. It says 'dismiss or hide from view,' implying a reversible view-level action, yet the name 'delete_job' implies permanent removal; the description never states which is true, whether data is destroyed, or whether the action can be undone. That destructive-vs-reversible ambiguity is the single most important behavior for the agent and it is left unresolved.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
