Lowys Method

Category: Engineering  ·  Sub-category: architecture  ·  Last updated:
Expert orchestrator for Juval Löwy's system design methodology from *Righting Software*. Use this skill whenever the user mentions Löwy, "The Method", volatility-based decomposition, layered architecture with Managers/Engines/ResourceAccess, use case validation, call chains, composable design, the Message Bus pattern, or asks to architect or decompose a system. Also trigger when the user mentions "functional decomposition" (to warn against it), "domain decomposition", "core use cases", "axes of volatility", or "Design Don'ts". This skill routes to specialized sub-skills for each phase of The Method. Always trigger this skill for architecture-level design conversations, even if the user does not name Löwy explicitly - the vocabulary is the signal.
