architecture-viz
Generate an interactive, navigable system-architecture diagram from a build idea or design.md, so you can SEE the architecture (not just read prose decisions) and click any component to its constraint-matrix + ADR. Use for pre-/cook brainstorming, /cook Phase 1.5–2 design review, or visualizing an existing build. Triggers: "visualize the architecture", "diagram this system", "/architecture-viz", "show me the architecture", "draw the system", "architecture diagram". Builds on LikeC4 (free, local, git-tracked, no Docker). Distinct from the Architecture Soundness Gate (text-only decision gate in system-design-fundamentals.md) — this is its VISUAL companion. Distinct from improve-codebase-architecture (refactors existing code) and dogfood (drives a running app).
