dev:architecture

Router for architecture knowledge — 7 architectural styles (layered, hexagonal, clean, modular monolith, microservices, event-driven, CQRS) and the 22 GoF design patterns.

Part of dev.

42 reference documents, about 14,081 lines.

The skill itself does not contain them. It reads your question and names the one or two worth opening — which is the point, because loading everything below to answer one question would cost more than the answer is worth.

Reading these

You do not open these yourself in normal use — /dev:architecture picks for you. Read them directly when you want the reference rather than the answer, or to check what the advice is actually based on.
