Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Although schema description coverage is 100%, the schema exposes four unrelated optional parameters: url, host, json, and zone. The description only makes sense for url and does not reconcile how host, json, or zone relate to URL normalization. This is likely to confuse an agent into passing the wrong parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
