context-engineering vs STS2MCP

context-engineering: Context engineering is the practice of providing LLMs with comprehensive context from various sources. It emphasizes that quality and completeness of context matter more than prompt wording. This repository is a companion resource for a book on context engineering, containing examples and an online prompt builder.; STS2MCP: STS2MCP is an experimental research mod for Slay the Spire 2 that enables AI agents to play the game. It exposes game state and actions via a localhost REST API, with an optional MCP server for Claude Desktop/Claude Code integration. It supports both singleplayer and multiplayer co-op, and has been tested against STS2 v0.99.1.
