This skill should be used whenever domain modeling is taking place. It provides specialized guidance for type-driven and data-driven design based on Rich Hickey and Scott Wlaschin's principles. The skill helps contextualize current modeling within the existing domain model, identifies inconsistencies, builds ubiquitous language, and creates visualizations (Mermaid, Graphviz/DOT, ASCII diagrams) to communicate domain concepts clearly. Use this skill when designing types, modeling business domains, refactoring domain logic, or ensuring domain consistency across a codebase.
Create architectural floor plans and interior layouts using drawio XML format with building-standard symbols. Best for office layouts, home floor plans, evacuation plans, and seating arrangements. Built on drawio with floorplan-specific stencils. NOT for simple diagrams (use mermaid) or UI wireframes (use wireframe skill).
BDD-style behavior specification engine for the skill system. Use when: (1) defining a new skill's behavior before implementation, (2) validating a spec against the schema, (3) generating a behavior contract (Mermaid DAG) from a spec, (4) running structural acceptance tests against a built skill. Workflow: Spec → Test → Develop → Contract.
Create data analytics and data pipeline diagrams using PlantUML syntax with analytics/database stencil icons. Best for ETL pipelines, data lakes, real-time streaming, data warehousing, and BI dashboards. NOT for simple flowcharts (use mermaid) or general cloud infra (use cloud skill).
Create complex directed/undirected graphs with automatic layout using DOT language. Best for dependency trees, module relationships, package hierarchies, and call graphs. Use when you need fine-grained edge routing or hierarchical layouts with many levels. NOT for simple flowcharts (use mermaid), data charts (use vega), or network topology with device icons (use network).
General Technical Design Document Summarization Skill: Scan documents and diagrams in the current execution directory (Markdown, PlantUML/Mermaid, drawio, images, etc.), extract system objectives, module boundaries, core processes, sequences and states, and output structured technical design documents. Use this skill when users mention "technical design documents", "solution sorting", "summarize design based on existing documents", "summarize documents and diagrams in the directory", or "complete sequence diagrams/state diagrams".
Generate polished technical diagrams as SVG, and export PNG when local export tooling is available. Use when the user wants an architecture diagram, flowchart, data flow, sequence diagram, agent or memory diagram, comparison matrix, timeline, or concept map rendered as a visual artifact instead of Mermaid or a hand-drawn whiteboard. Trigger on requests like 画图、帮我画、生成图、 做个图、架构图、流程图、时序图、可视化一下, or English requests such as draw diagram, architecture diagram, visualize this system, generate a flowchart, or create a technical SVG. Prefer this skill when the user wants publishable SVG/PNG output, style selection, or AI/agent-system diagram conventions.
This skill should be used when the user asks to write, edit, review, or improve Markdown content (README, docs, changelog, guides), or needs Markdown formatting, syntax help, or advanced patterns (tables, callouts, task lists, mermaid, details/summary, footnotes).
Programmatic canvas toolkit for creating, editing, and refining Excalidraw diagrams via MCP tools with real-time canvas sync. Use when an agent needs to (1) draw or lay out diagrams on a live canvas, (2) iteratively refine diagrams using describe_scene and get_canvas_screenshot to see its own work, (3) export/import .excalidraw files or PNG/SVG images, (4) save/restore canvas snapshots, (5) convert Mermaid to Excalidraw, or (6) perform element-level CRUD, alignment, distribution, grouping, duplication, and locking. Requires a running canvas server (EXPRESS_SERVER_URL, default http://localhost:3000).
Generate Excalidraw diagrams from natural language descriptions. Outputs .excalidraw JSON files openable in Excalidraw. Use when asked to "create a diagram", "make a flowchart", "visualize a process", "draw a system architecture", "create a mind map", "generate an Excalidraw file", "draw an ER diagram", "create a sequence diagram", or "make a class diagram". Supports flowcharts, relationship diagrams, mind maps, architecture, DFD, swimlane, class, sequence, and ER diagrams. Can use icon libraries (AWS, GCP, etc.) when set up. Do NOT use for code architecture analysis (use the architecture skills), Mermaid diagram rendering (use mermaid-studio), or non-visual documentation (use docs-writer).
Render and customize assistant message text as markdown in assistant-ui. Use when displaying model output as formatted markdown with MarkdownTextPrimitive from @assistant-ui/react-markdown wired into the MessagePrimitive.Parts text branch, configuring remarkPlugins (remark-gfm, remark-math) and rehypePlugins (rehype-katex), or memoizing components with unstable_memoizeMarkdownComponents. Covers code-block syntax highlighting via react-shiki or react-syntax-highlighter registered as SyntaxHighlighter in components/componentsByLanguage, LaTeX math rendering with KaTeX, Mermaid diagrams gated on stream completion, custom math delimiters via preprocess, and the StreamdownTextPrimitive alternative from @assistant-ui/react-streamdown with built-in Shiki/KaTeX/Mermaid and block streaming. For general chat UI composition route to primitives.
Analyze source code and produce an enterprise-quality, domain-organized Wiki under `.nium-wiki/`. Trigger on: "generate wiki", "create docs", "update wiki", "rebuild wiki", or any documentation generation request. Capabilities: - Semantic code analysis — understands logic, not just structure - Auto-generated Mermaid diagrams (architecture, data flow, class, dependency) - Bidirectional cross-linking across all documents - SHA256-based change detection for incremental rebuilds - Every section traces back to source via relative path links - Multi-language output (zh/en/ja/ko/fr/de and more)
