Score: 7.8/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 8)

Ktx is a self-improving context layer that teaches AI data agents how to accurately query data warehouses by automatically building semantic layers, ingesting business knowledge from wikis and tools, and resolving join traps and metric definitions. It fills a clear gap between general-purpose agents and traditional semantic layers by combining automated context building, contradiction detection, and read-only agent execution via CLI and MCP, making it a promising tool for teams wanting reliable agent-driven analytics.
