Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so safety is covered. The description usefully adds what fields come back and that results are limited to outcome states (no bids / adjudicated), but says nothing about pagination, empty results, or whether a company not in insolvency returns nothing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
