# Create Architecture Diagrams

Architecture diagrams are the lingua franca of software engineering. They communicate how systems are structured, where data flows, and which services depend on each other. But creating them in tools like Lucidchart or draw.io is tedious -- dragging boxes, aligning arrows, and fiddling with layout eats time that should go into design decisions.

The generate_diagram skill turns a text description of your architecture into a polished diagram automatically. Describe your services, databases, message queues, and connections in plain language, and get back a properly laid-out diagram with clear labels and logical grouping. The AI understands common architecture patterns -- microservices, event-driven, layered, hexagonal -- and applies appropriate visual conventions.

This is invaluable for technical documentation, design reviews, onboarding materials, and architecture decision records. Instead of spending an hour arranging shapes, describe what you built and get a diagram in seconds. Update the description when the architecture changes and regenerate -- no manual layout work required.
