Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description must carry behavioral disclosure. 'Find' implies read-only, non-navigating behavior, and the substring criterion is stated. However, it does not mention what is returned on success or failure, whether matching is case-insensitive, or whether search is scoped to a specific browser.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
