What problem does it solve? Creating polished technical architecture diagrams usually requires dedicated diagramming tools, accounts, or rendering libraries. This Skill produces professional dark-themed architecture, cloud, 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, including frontend, backend, database, cloud, security, message bus, and external services. - Structured Layout Rules: Enforces spacing, z-order, arrow styling, boundary rendering, and legend placement so diagrams remain readable and consistent. - Self-Contained Output: Generates one HTML file with inline CSS and SVG, no JavaScript, that renders offline in any modern browser. - Use Case: Describe a microservices system with a VPC, subnets, databases, and a message queue, and receive a ready-to-open HTML diagram with region boundaries, security groups, and a legend. ## Quick Start Ask the agent to generate an architecture diagram of your system as an HTML file, describing the components, connections, and technologies involved.
