• AgenticSTS — Research testbed for long-horizon language-model agents on Slay the Spire 2, built around bounded, typed memory instead of a growing transcript. Reports 3/10 wins at Ascension 0 without learned skills and 6/10 with them.
• ai-spire — Slay the Spire 2 mod that asks an OpenAI-compatible model (DeepSeek by default) for decisions, adds Spire Codex card data to its prompts, and falls back to a rule engine when the API call fails.
• CommunicationModExtension — Adds socket communication and save/load-state commands to Communication Mod.
• Communication Mod — A ModTheSpire mod that launches an external process and talks to it over stdin/stdout, sending game state as JSON and accepting text commands. Most Slay the Spire bots are built on it.
• LudicrousSpeed — Mod that lets a calling library execute commands in the real game, optionally very quickly, for AI projects.
• MCPTheSpire — Slay the Spire mod that runs an MCP server inside the game (Streamable HTTP on port 8080) with tools to read state, play cards, choose options and start runs, so language-model agents can play.
