I made a SlayTheSpire2 AI that wins 86% of runs at A0

Full write-up here. I also released ~5k run logs here.

This is the first milestone of my project, and currently it can only play Ironclad. I haven't yet measured the A10 win rate, but my next milestone is winning A10 at >50% win rate. I have spent ~7 months on this project, starting in March.

A large portion of this project was done via coding agents (I used Claude/Gemini).

The clip is made by creating a mod that can interfaces with the game, via HTTP.

Happy to take any questions :)
