Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so slug, detail, and country are already documented in the schema, making 3 the baseline. The description gestures at the detail enum's effect but does not add syntax, format, or fallback meaning beyond what the schema string already says.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
