What problem does it solve? Creating professional-looking technical architecture diagrams usually requires dedicated diagramming tools, licenses, or rendering libraries. This Skill generates polished, dark-themed architecture and infrastructure diagrams as single self-contained HTML files with inline SVG, requiring no external tools, API keys, or dependencies. ## Core Features & Use Cases - Semantic Color System: Predefined fill and stroke palettes categorize components by type (frontend, backend, database, cloud, security, message bus, external) for instantly readable diagrams. - Complete Design System: Includes typography rules, grid backgrounds, arrow styles, security group boundaries, region boundaries, and legend placement logic, plus a full HTML template with working component examples. - Use Case: Describe your system (e.g., a React frontend, FastAPI backend, PostgreSQL database, and AWS S3 storage behind CloudFront) and receive a single .html file you can open in any browser, share with your team, or embed in documentation. ## Quick Start Generate an architecture diagram of my web application with a React frontend, Node.js API server, and PostgreSQL database, and save it as an HTML file.
