I was able to make something work. Basically you're right, there is no "Cut" or "Add Edit" function available in ExtendScript. Why? I have no idea, since Premiere is an editing program, you think Adobe would make this available, since the "Add Edit" function is under Sequence > Add Edit (Control + K).
So, here is a very basic and heavily commented small piece of code. It just performs a cut at the playhead time, or performs multiple cuts based on a collection of time objects.
Please feel free to read out to me if you have any questions.
// PSUDO-PROGRAMMING CODE STEPS I TOOK JUST TO MAKE A CUT USING EXTENTSCRIPT IN PREMIERE PRO
// 0. get the project item reference from selected clip, clip.projectItem
// 1. get video track that the clip is on
// 2. get the play head position, just incase you want to visualize the cuts being made
// 3. calculate the time of the clip the playhead is over, that will be the in point, and get the out point
// 4. set the project item in point and out point, for video, audio, or all
// 5. insert the clip onto the track at the playhead position track.overwriteClip();
// 6. deselect the track to avoid any issues
function main(cutPositions)
{
var activeSequence = app.project.activeSequence;
if(activeSequence)
{
// get selection of track items
var trackItems = activeSequence.getSelection();
if(trackItems.length > 0)
{
// CAVEAT: linked video and audio track items on the same track,
// example: track item on Video 1 and Audio 1, video track item will appear first in the array.
// however, if video track is on Video 2 and audio track is on Audio 1, audio track item will appear first element in array.
// ARE YOU LOOKING AT ONLY CUTTING VIDEO TRACKS OR AUDIO TRACKS?
// get track item type you want to reference in your selection of track items.
var mediaType = 'Video'; // or 'Audio'
var tracks = (mediaType == 'Video') ? activeSequence.videoTracks : activeSequence.audioTracks;
// remove the track items from the selection you don't want to process
for(var i = 0; i < trackItems.length; i++)
{
var trackItem = trackItems[i];
// we will use the "mediaType" STRING, instead of the "type" INT
// trackItem.mediaType == "Video" or trackItem.mediaType == "Audio"
// INSEAD OF
// trackItem.type == 1 or trackItem.type == 2
// if track item is not the media type you initialized above, then remove it from the array
if(trackItem.mediaType != mediaType)
{
trackItems.splice(trackItems.indexOf(trackItem), 1);
}
}
// loop over all the track items in the new array and do cuts
for(var i = 0; i < trackItems.length; i++)
{
// USE THIS VARIABLE TO PASS INTO OTHER FUNCTIONS TO REFERENCE THE CURRENT TRACK ITEM BEING WORKED ON
var trackItem = trackItems[i];
for(var j = 0; j < tracks.length; j++)
{
var track = tracks[j];
var clips = track.clips;
for(var k = 0; k < clips.length; k++)
{
if(clips[k].name == trackItem.name)
{
trackItem.track = track; // used to store the track that our track item is on
}
}
}
// just check if the track item is on a track, which it should be, if not do nothing
if(trackItem.track == null) return;
// THIS PART IS SUPER IMPORTANT, ADDING 2 TIME OBJECTS TO THE TRACK ITEM FOR REFERENCE LATER
// get the sequence time of the playhead
trackItem.sequencePlayheadPosition = activeSequence.getPlayerPosition();
// get the track item time of the playhead
trackItem.playheadPosition = new Time();
trackItem.playheadPosition.seconds = trackItem.sequencePlayheadPosition.seconds - trackItem.start.seconds + trackItem.inPoint.seconds;
if(cutPositions)
{
// THIS IS PROBABLY WHAT MOST PEOPLE WANT TO DO
cutFromTimeArray(trackItem, cutPositions)
}
else
{
// JUST A BASIC CUT AT THE CURRENT PLAYHEAD POSITION
cutFromPlayhead(trackItem);
}
// deselect the everything and update the UI
var itemsToDeselect = activeSequence.getSelection();

// USE ONE AT A TIME, SINCE EVERYTIME IT IS RUN, IT DESELECTS EVERYTHING
// DO SINGLE CUT AT PLAYHEAD POSITION
var cutPositions = []
cutPositions.push(app.project.activeSequence.getPlayerPosition());
main(cutPositions);
// OR
// MULTI-CUT, MAKE AN ARRAY OF TIME OBJECTS
// in my example, I made 3 cuts, one at the playhead time, the others 1 and 2 seconds after playhead time
var cutPositions = [];
var cut1 = app.project.activeSequence.getPlayerPosition();
cut1.seconds = cut1.seconds + 1; // first cut 1 second after playhead
var cut2 = new Time();
cut2.seconds = cut1.seconds + 1; // 1 second ahead of the first cut
var cut3 = new Time();
cut3.seconds = cut2.seconds + 1; // 1 second ahead of the second cut
cutPositions.push(cut1, cut2, cut3); // put all the cut times (based on sequence/playhead time) into an array
//main(cutPositions);
