What problem does it solve? Writing Mermaid diagrams by hand often produces syntax errors, harsh default styling, and unreadable layouts, and rendering them to shareable image formats requires manual tooling setup. ## Core Features & Use Cases - Diagram Creation: Generates Mermaid code for 20+ diagram types including flowcharts, sequence diagrams, ERDs, C4 architecture, AWS architecture-beta with service icons, state machines, and git graphs, with curated color palettes and styling rules applied by default. - Validation and Rendering: Validates .mmd syntax before rendering and outputs SVG, PNG, or ASCII using mermaid-cli, beautiful-mermaid, or a Puppeteer pipeline with Iconify icon pack support. - Code-to-Diagram Analysis: Analyzes existing codebases (ORM models, API routes, module dependencies) to generate ERDs, sequence diagrams, and architecture diagrams from source code. - Use Case: Ask the agent to visualize your NestJS order service as a C4 Container diagram; it reads the code, generates styled .mmd source, validates it, and renders a PNG for your architecture documentation. ## Quick Start Ask the agent to create and render a flowchart of your login process as an SVG file.
