How would you sum up Prototype Ayaka based on everything we have of her?
Just Prototype without taking anything from the HimuTen side? I'd say Ayaka is particularly difficult to summarize because there's so little content it's easy to accidentally say everything instead.
The key concept of Ayaka is the weakest Master pulling the strongest Servant. She sucks as a mage because her mother died before Fragments and her father and sister died during it, leaving her without a teacher, and being raised in normal culture, which amplified her natural repulse toward sacrificing animals for her witchcraft. Living the other half of her life with Manaka's perfection as a measuring stick certainly didn't help her opinion of her talents either.
But the surprise with Ayaka is that she really doesn't want to get involved with the Holy Grail War but once summoning Arthur forces her into the game, she plays to win. Her opinion on herself is as low as it can get and she has no backbone interacting with anyone else, but Saber is her partner, so with him specifically, she lets him know she's boss.
Along their battle together, Ayaka grows stronger thanks to Arthur pointing out she's not built for her family's edgy curses and would be better off sticking to generic elemental Formalcraft, something she never tried to invest into before because she considered it magecraft for dumb people. As Mashin puts it, she gets really powerful at the cost of her standout traits.
But I guess what really matters about Ayaka is that she's a prototype, so a lot of her defining traits were already inherited by Shirou (randomly summons Saber when Lancer is about to kill him thanks to a relic sealed inside him), Rin (the double tsundere dynamic between girl determined to win and the jaded knight), her western name order counterpart (the initial arrangement of the girl who actively wants to avoid the Grail War and the dynamic with Saber being the only person she pushes back against), and Haruri (soft-hearted dark mage that pays for her curses with her own blood and skin because she can't bring herself to perform normal sacrifices).
The only main Ayaka characteristic that wasn't already picked up and developed through another character is the part about her being really pretty without her glasses, to the point Gilgamesh fell for her the moment he saw her without them. This "beautiful without glasses" trope is normally a completely incorrect opinion some people have, but in Ayaka's case, removing her glasses changes her hair color from black to brown, so there's genuinely some mysterious transformation effect going on here. I wonder if it will ever be explained.
