 | optional      | Set to `true` if you want to mark argument as optional. When not provided, argument is considered to be required (Raycast will not allow to execute the script if argument input is empty)  | No       | 1.3.0+      |
+| percentEncoded| Set to `true` if you want Raycast to perform percent encoding on the argument value before passing it to the script. Can be handy for scripts that pass argument directly to URL query  | No       | 1.4.0+      |
 
 **Maximum number of arguments:** 3 (if you feel it's not enough for your use case, please let us know via feedback or in the [Slack community](https://www.raycast.com/community))
