Description
Diagram Design is an innovative agent skill designed to generate editorial-quality diagrams directly from natural language prompts. It integrates seamlessly with popular agent hosts such as Claude Code, Codex, Pi, GitHub Copilot, Cursor, Factory Droid, and Qoder, allowing users to create sophisticated visuals without leaving their existing environment. The core premise is to provide 'taste' to AI models, ensuring that the generated diagrams are not only accurate in content but also aesthetically pleasing and brand-consistent.

The skill offers a comprehensive library of 45 distinct diagram types, including architecture, Sankey, heatmap, exploded axonometric, database schema, and more. Each type adheres to its own specific rules, ensuring visual integrity and avoiding generic, 'rounded-box' aesthetics. A key feature is its ability to brand-match diagrams to a user's website. By simply pointing the skill at a URL, it extracts colors, fonts, and other stylistic elements, applying them to every generated diagram within about 60 seconds. This ensures that all visuals align with the user's established brand identity.
Diagrams are produced as self-contained HTML + SVG files, which can be opened offline with a double-click, requiring no build steps, dashboards, or hosting. This makes them highly portable and easy to share. The tool also supports importing and redrawing existing diagrams from popular formats like draw.io, Mermaid, and Excalidraw. Instead of merely converting, Diagram Design intelligently redraws these sources to fit the desired size, detail, and audience, applying its editorial style.
Accessibility is a core consideration, with diagrams designed to be screen-reader friendly, announcing titles and descriptions rather than just blank rectangles. Optional accessible motion can be added to diagrams to enhance explanations, with static output as the default. The skill also includes advanced features like two new axonometric types for exploded views and plan layouts, and a robust design system that prioritizes clarity, hierarchy, and a clean aesthetic with specific rules for color, typography, and spacing.
Installation is straightforward, typically involving adding the skill via a command-line interface or marketplace within the agent host. Users interact by describing their desired diagram in plain English, with no complex syntax or configuration required. The output quality depends on the underlying model, and while the results are not editable source formats like traditional design files, diagrams can be regenerated by asking the agent again or by directly editing the SVG. For those needing to customize the style guide, an editable installation option is available, and named profiles allow for managing multiple client brands efficiently.
