Eraser Diagram Generator

Generates architecture diagrams from code, infrastructure, or descriptions. Use when user asks to visualize, diagram, or document system architecture.

Generate REST API endpoints with proper structure, validation, error handling, and types. Use when creating new API routes, endpoints, or backend services.

Academic-first Draw.io figure skill for papers, theses, IEEE-style diagrams, architecture figures, workflows, roadmaps, formulas, and publication-ready visualizations. Use when users ask to draw, redraw, replicate, edit, or export diagrams for academic papers or technical documents. Creates offline .drawio + .spec.yaml + .arch.json bundles, exports SVG locally, uses draw.io Desktop CLI for embedded SVG/PNG/PDF/JPG, supports style presets, self-check review loops, and diagrams.net URL fallback without requiring MCP.

Desktop-first Draw.io diagram creation, editing, replication, and conversion (redraw, remake, 重画, 绘图, 画图, 做个图) with a YAML design system supporting 6 themes. Use when creating visual diagrams, drawings, figures, schematics, charts, system architecture diagrams, network diagrams, flowcharts, UML, ER diagrams, sequence diagrams, state machines, org charts, mind maps, cloud infrastructure diagrams, research workflows, paper figures, IEEE-style diagrams, technical roadmaps, or diagrams containing formulas, equations, LaTeX, AsciiMath, MathJax, inline math, block math, 公式, 行内公式, or 行间公式. Academic-paper requests should classify the figure as architecture, roadmap, or workflow, then deliver the editable offline bundle plus SVG by default. Accepts Mermaid, CSV, and YAML input; convert to drawio from mermaid to drawio or any structured source. Default to offline/local generation with `.drawio` + sidecars; use an optional live backend only when browser or inline refinement is genuinely needed.

REST and GraphQL API architect for designing robust, scalable APIs. Use when designing new APIs or improving existing ones.

Proactively suggest diagrams when explaining complex systems. Triggers on diagrams, charts, visualizations, flowcharts, sequence diagrams, architecture diagrams, ER diagrams, state machines, Gantt charts, mindmaps, C4, class diagrams, git graphs. Use when user asks for visual representations of code, systems, processes, data structures, database schemas, workflows, or API flows. Generate Mermaid diagrams in markdown.
