Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the baseline is 3, but the description meaningfully constrains the 'name' parameter by stating it must be the exact name returned by search_templates, and it hints that localization affects returned fields ('localization data'), which ties the uiLanguage parameter to its effect.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
