you need to put a comment, right before the action:
// use: [skills]

example:Code:

---

define _radius,skill41;
define _height_length,skill42;
define _base_length_x,skill43;
define _base_length_4,skill44;
 
// use: _radius, _height_length, _base_length_x, _base_length_y
action blablabla
{
...
}

---

EDIT:

lol, forgot about that ^^
