 ## Synopsis
 
-Creates an array from the given elements (strings, numbers, arrays, or objects).
+Wraps a single value (string, number, array, or object) in an array.
 
 ## Syntax
 
 ```Syntax
-array(<element1>, <element2>, ...)
+array(<value>)
 ```
 
 ## Description
 
-The `array()` function creates an array from the provided arguments, allowing
-mixed data types within the same array. Unlike `createArray()` which requires
-all elements to be the same type, `array()` accepts any combination of strings,
-numbers, arrays, and objects as arguments.
+The `array()` function returns a new array containing the single input value.
+The value can be a string, number, array, or object. Use
+`createArray()` to construct arrays with multiple elements of the same type.
 
-This function is useful when you need to combine different types of data into a
-single collection, such as mixing configuration values, computed results, and
-structured metadata in deployment scenarios.
+This function is useful when a schema expects an array, but you only have a
+single value, or when you need to nest an existing array or object inside an
+outer array.
 
 ## Examples
 
-### Example 1 - Build a deployment plan
+### Example 1 - Wrap an existing array as a single element
 
-This example demonstrates combining different data types to create a comprehensive
-deployment configuration. The array contains an existing server list, a numeric
-batch size, and a configuration object with deployment strategy details.
+This example demonstrates wrapping an existing server list into a single array
+element, producing a nested array. This can be useful when a downstream schema
+expects an array of arrays.
