Generate Excalidraw diagrams (.excalidraw JSON files) for whiteboarding, flowcharts, architecture diagrams, sequence diagrams, mind maps, wireframes, and org charts. Use when user requests diagrams, visual documentation, system architecture visualization, process flows, or any hand-drawn style diagram. Triggers on requests mentioning Excalidraw, diagram creation, flowcharts, architecture diagrams, sequence diagrams, wireframes, or visual documentation.

Generate GraphViz DOT files (.dot) for directed/undirected graphs, hierarchical layouts, network diagrams, dependency graphs, state machines, and complex graph visualizations. Use when precise node positioning is needed, when rendering to PNG/SVG/PDF is required, when complex graph algorithms (clustering, ranking) are needed, or when dealing with large graphs (100+ nodes). Triggers on requests mentioning GraphViz, DOT language, network diagrams, dependency graphs, or when sophisticated graph layout is required.

Build terminal user interface (TUI) applications with the Textual framework. Use when creating new Textual apps, adding screens/widgets, styling with TCSS, handling events and reactivity, testing TUI apps, or any task involving "textual", "TUI", or terminal-based Python applications.

Generate Mermaid diagrams (.mmd, .mermaid files, or markdown code blocks) for flowcharts, sequence diagrams, class diagrams, ER diagrams, state diagrams, Gantt charts, pie charts, mindmaps, timelines, and git graphs. Use when user requests diagrams for documentation, markdown files, README visualizations, or any text-based diagram format that renders in GitHub/GitLab. Triggers on requests mentioning Mermaid, markdown diagrams, documentation diagrams, or when output needs to be embedded in markdown.
