SkeletIQ is an architecture design platform built for AI coding agents and the engineers who direct them. Users describe a system in plain English and SkeletIQ generates a complete architecture with services, data flows, connections, and cloud cost estimates across AWS, GCP, and Azure. The tool then critiques the design using rule-based analysis to flag single points of failure, missing cache layers, and compliance gaps. Designs can be released and handed to coding agents over MCP, providing a structured brief, a deterministic build order, and a drift report comparing what was built against the original specification.
