From Vintage Story Wiki
The most important property when creating an asset is the code, also known as an ID. To begin, copy and paste this into the opened simplewand file.
{
"code": "simplewand"
}
Remember that json files are a set of keys to values. The key, in this example, is "code", and the value is "simplewand". Note that the item file starts and ends in curly brackets ({ }), meaning it is a single object.
