Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full disclosure burden. 'Get' implies a read, but nothing is said about required permissions, whether an empty result is returned for posts with no SEO meta, or what fields the meta contains. For a read tool with zero annotation coverage this is thin, though the read-only nature is at least implied.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
