How do I go about adding a script component to any gameobject instanced in scene view .

i.e If i create a new Cube or a point light, a particular script will get attached to it .

I ave been looking at AssetPostprocessor but i did not find an answer there . the closest thing was using ModelImporter to get between the import process of models . but this will only work for models , models imported into unity.

You can use GameObject.AddComponent:

For example when the following script is attached on GameObject1 in the scene, when it is clicked, it will first create a cube primitive in the scene, and then add a CustomMonobehaviour to it:

public class AddBehaviour : MonoBehaviour {

    // Use this for initialization
    void OnMouseDown() {

         GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Cube)
         cube.AddComponent<CustomMonoBehaviour>(); 

    }

}

This seems to be what you want.
