Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It explicitly states multiple behavioral traits: read-only, blocks unsafe/private targets, does not follow redirects, never calls Indexing API, never mutates Search Console. These are clear and accurate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
