# Technical Overview Functional Architecture Diagramming ## Overview This skill now directly contains the merged specialist doctrine that previously lived in the legacy system-functional-architecture skill. ## Integrated Legacy Specialist Doctrine (Preserved and Merged) # System Functional Architecture Diagramming ## Overview This is the architect-private skill for drawing and reviewing **系统功能架构图** in the **概要设计** stage. It strengthens a generic diagramming meta-spec with the architecture-lifecycle requirement that a functional architecture diagram must answer, at minimum: - 系统建设目标是什么 - 要有哪些功能 - 这些功能如何分层 - 哪些功能是核心闭环，哪些是支撑能力 - 功能之间如何协作，但不过早坠入技术实现细节 Core principle: **系统功能架构图 belongs to overview design, so it should explain capability structure and layering, not code structure, deployment topology, or runtime sequence detail.** This skill exists because many so-called “功能架构图” fail in one of two ways: - they are only a feature list with boxes, but no layering logic or system goal - they collapse into technical architecture, process flow, or deployment views and lose their functional-design role Use this skill to produce a diagram that is abstract enough for 概要设计, but concrete enough to guide later system architecture, technical architecture, and detailed design. Canonical full-fidelity drawing spec: - `references/universal-diagramming-spec-full.md` Important preservation rule: - the full drawing/detail content from the source publication is preserved there verbatim - ...
