Intermittent Clutch slippage Vibe

2003 Pontiac Vibe (base), 1.8L
170,000 miles
Would there be any other explanations beside a bad clutch for an intermittent slippage issue?
About 2 months ago the clutch stated to slip when shifting into 2nd and 3rd or upon heavy (for a base vibe) acceleration.
Tried the put it in 2nd or 3rd and let the clutch out to see if it dies test and it instantly died - so clutch OK???
Checked the fluid level in the master cylinder and it was low (just below the min level) so I added fluid. Problem seemed to go away.
Clutch starting slipping again this week. Checked the brake fluid level and it still full.
Anything else to look at?
Thanks!

Fluid loss without leakage could indicate disc wear. First high chance is clutch is worn out. Your test with a higher gear is fair only to guess wear on a clutch but definitely bad if it doesn't stall.
Outside chance that oil or fluid is getting on friction surface but doubt that,

Thanks.
How long will a clutch last after it starts to slip?
This is way beyond my skill level so I'll need someone to replace it for me. Is there anything else I might as well have replaced while the car is taken apart?
I'll have a new driver at the end of this month and this will be his sh*tbox to drive around at a low insurance rate. Else I would probably just sell the car.

How long totally depends on how it is driven. I could smoke it in one day if i tried to.
You should automatically change the clutch, pilot bearing, pressure plate and throw out bearing. With all the slippage yours has seen, you should change the flywheel also.

How long if really slipping?:
Charge cell phone and bring good shoes now! No telling really. If you saw how little friction material is really on them new you'd be shocked they last at all.
OK: This could actually be original wholly depending on driving habits. Some folks this is like changing oil others you never hear of it - go figure but makes sense. The thing to do if you wish to risk nursing it is just time the shifting with engine speeds as best you can such that there's minimal slipping.
Most all hydraulic linkages are self adjusting but check this anyway: Little finger type effort push and feel free-play at top of clutch pedal everything off engine and all. Now, while accelerating or deceleration (less common to me) that free-play must be there. IF you notice it's gone under higher torque loads the thing is riding itself by itself without you doing it assertively! It does happen more often with adjustable types and or when an engine trans as an assembly might move against cables or linkage or rods. Unfortunately it happens by mechanic error adjusting one the is adjustable for any reason WRONG.
Guess for this: It needs an entire inch or inch and a half of a free-play zone felt at pedal.
Otherwise this is fairly typical for a worn clutch. At first you notice RPMs go up but speed isn't and soon after you are rendered a pedestrian - not funny some don't give much warning, some might?

Said that for most. Only some VERY old ones you set once that I recall, VERY OLD! T

As far as the other things to change while doing this I was thinking about unrelated items that may be disturbed while disassembling the car to get to the clutch.
The videos I watched show partially pulling the engine. So are there any parts that otherwise would be a b*tch to replace if you didn't have the car partially disassembled.

No telling what might break in course of doing this? If as you said earlier you just want this as a "sh*t box" and risk wasting time just get a clutch disc and forget all the rest and put up with it not lasting or behaving perfectly. That's an end game to stop it from slipping for now not a respectable fix.
If you need to tilt and remove stuff things might break and or leak that were fine before. No telling for sure.
Other is find a tech or shop that will knowingly do this for you at rock bottom "make it move" understanding that there's no clue if it would work properly if anyone will.
Not this but I have on a flipping truck owned by workers at my place that blew a clutch and said NO, too heavy for me but they couldn't leave so said fine - go get this only (totally rusted out 100% junk truck) and YOU do the holding of parts while I put just a disc in it so it would get the hell off my place!
If any on this job is misunderstood you can end up with it all worse than not touching it,
