Does it support custom colors and styles?

Yes, the skill can configure stroke colors, fill patterns, and font sizes (S, M, L, XL) to match your visual requirements.

What types of diagrams can I create?

You can create flowcharts, sequence diagrams, block diagrams, Entity Relationship Diagrams (ERDs), and presentation slides using frames.

Can I use frames for presentations?

Absolutely. The skill supports frames, which act as artboards or slides for organizing different parts of a presentation within a single diagram file.

Can I open the generated files in the Excalidraw web app?

Yes, this skill generates standard .excalidraw JSON files that are fully compatible with excalidraw.com and other Excalidraw-supported tools.

Does it handle arrow connections automatically?

Yes, the skill manages complex bindings, ensuring that arrows are correctly attached to shapes and that connections are bidirectionally referenced in the JSON data.

Design Tools

Generates professional, hand-drawn style Excalidraw diagrams for technical documentation and architectural mapping.

About

This skill enables Claude to generate valid .excalidraw JSON files, allowing for the automated creation of flowcharts, ER diagrams, sequence diagrams, and system architectures. It handles the complex logic of coordinate positioning, bidirectional element bindings, and schema validation, ensuring that generated files are ready for immediate use in Excalidraw. By providing domain-specific guidance on arrow routing and container management, it bridges the gap between conceptual descriptions and structured visual assets.

Key Features

Supports specialized elements including polygons, frames, and hand-drawn paths
Automates layout logic with precise positioning and element spacing
Generates valid .excalidraw JSON schema version 2 files for direct import
2 GitHub stars
Manages bidirectional bindings between arrows, shapes, and text containers
Configures visual styling for stroke, fill patterns, and typography scales

Use Cases

Visualizing system architectures and cloud infrastructure designs
Generating Entity Relationship Diagrams (ERDs) for database modeling
Creating flowcharts and sequence diagrams for software logic documentation
