Architecture work reuses before it creates.architect-design looks for an adequate prior design or existing capability first and creates no new artifact when no real choice remains. A Stage-0 concept is a valid final answer, not a waypoint to a full design.
Architecture reviews challenge unnecessary surface.architect-review gained a design-doc reduction pass covering unnecessary components, services, dependencies, boundaries and custom mechanisms; ignored standard, native or provider capabilities; speculative scale and configurability; and complexity no named quality attribute supports.
