Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description provides zero explanation for any of the parameters. With 2 required parameters and numerous optional flags (news, nometa, all_words, titles_only, attachments with enum '0','1','only'), the description must compensate for the schema's silence on semantics, but it does not. Parameter names like q and limit are self-evident, but many others are cryptic without explanation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
