Hello there, thank you for reading this.
Weapon power Skye is not a very easy route to play, Skye is just a hard hero to play, but if you have the basics of the game down you can handle her. When going weapon power you need to have a lot of fire power, she can attack quite fast, but you want her to attack when you want her to attack and not have to wait for when she decides to be done with reloading or something. So what you do is start the match with some weapon power and attack speed(and a potion), it doesn't do great damage but it'll get better. When you've got the money go buy yourself some boots and more attack speed(weapon power is nice too but it comes after those two things), then you'll see that you can attack fast enough, so you probably have less problems farming, which is good, because when you can you should now buy a tension bow, it's a good bit of somewhat early game damage and is needed of you want to effectively fend off enemy heroes. Then, if you're probably killed a couple of times since the last time you bought something, buy a reflex block, it helps. Then after that start with the tornado trigger and tyrants monacles, they insure ctitical hits and do a crazy amount of damage if you attack enough times. When you get this far you probably already have your ult, if not, get your ult. The ult has a special role when playing skye, it doesn't do that much damage, but it stuns in the beginning and slows until the end, and that's all precious time you can use to destroy them with your basic attacks. If you did this right you'd have already won the game, but if your opponent is harder to beat then you expected you must buy the boots of course(if you didn't do that earlier on), then you buy some shield because the abilities from the enemy do a really good bit of damage, and then just go for infusions, if you don't win with that setup i don't know what else will.

Okay, this is probably a build you should try before doing weapon power but it's alright if you don't, I guess. Crystal power Skye is somewhat less hard to play then the weapon power skye, you rely more on abilities which you can use from farther away then your basic attack, so you can keep more distance between you and the enemy. You begin with just a crystal bit and some attack speed(you don't really need a battery because skye can use her abilities a lot before she runs out of mana). You don't do that much damage eh, but it'll get better, just get some more crystal power then, while you're at it just get a little battery too, and boots, and even more attack speed. You'll get to a point where you just don't do any damage anymore, that's when you start with getting a broken myth(though you'll buy it somewhat later), the first item you'll need is aftershock(I know it sounds strange right?) Because it gives you a lot of crystal power and you can combine it with your blazing salvo to get as much attack speed as you want. Then you go for alternating current because when your abilities aren't ultra strong, you're going to need every bit of damage you can(plus the bit of lifesteal sometimes is a lifesaver). By now you have your ult, but it reloads so slow, so get the clockwork(it really helps in dire situations). When you have that you can prioritize the broken myth(if you didn't already buy it), the extra damage that does to tanky heroes is a lot, so it helps a lot too, then you can just go halcyon chargers and aegis because you still need to be able to escape from enemies when needed, and then just go for infusions(but you'll probably have won whe game before you can begin with infusions). That was it, hope you enjoyed it...
