An AI agent clears Slay the Spire 2 on Ascension 8 and open-sources its harness

AgenticSTS has cleared Slay the Spire 2 on Ascension 8. The post says the project’s harness and trajectories are open-sourced, making it a reproducible agentic benchmark/demo rather than just a one-off clip.

This is a notable agent execution example: it shows an AI system completing a nontrivial game challenge and sharing the underlying infrastructure for others to inspect or reuse.
