**Design scalable systems the way strong engineers actually do — by reasoning, not by memorizing diagrams.** A divide-and-conquer wiki of composable building-block skills for Claude Code: clarify requirements, size with numbers, compose the right components, justify every trade-off, and stress-test for failure — then score and persist the design. Works in Claude Code, and any agent that can run skills.
