Article Cover SVG Generation

Use this skill to turn an article topic into a clean, reusable SVG cover asset.

When To Use

• Blog or docs header images
• OG / social preview art
• Publication thumbnails or article hero graphics

Do Not Use

• Full illustrations, raster image editing, or photo compositing
• Slide-deck themes or multi-slide styling
• Flowcharts, technical diagrams, or whiteboard sketches

Inputs

• Required: article title, topic, or article file path
• Optional: subtitle, output path, aspect ratio, color mood, publication/brand context

Workflow

1. Check $ARGUMENTS. If the request does not include a usable topic or file path, ask for the article title or topic before generating anything.
2. Resolve the output target:

- if the user gave an explicit filename, use it - if the user gave an article file path, save alongside it or inside a nearby assets/ directory as {article-slug}-cover.svg - otherwise save as {article-slug}-cover.svg in the active working directory

1. Read $SKILL_DIR/references/DESIGN_SYSTEM.md before choosing shapes, color, or composition.
2. Distill the topic into:

- a main title - an optional subtitle or kicker - one dominant visual metaphor - a layout pattern: Comparison, Flow, Centered Concept, or Typography-First

1. Draft the SVG using the design system rules for hierarchy, color contrast, and spacing. Favor one clear focal idea over decorative clutter.
2. Include SVG essentials in the generated file:

- root xmlns="http://www.w3.org/2000/svg" - a valid viewBox - accessible <title> and <desc> tags when practical - explicit font-family on text elements

1. Write the SVG to the resolved path.
2. Validate the result before finishing:

- tags close correctly - title remains readable at thumbnail size - text does not overflow the canvas - contrast is strong enough against the background

Output Contract

Return:

• the final SVG file path
• the chosen layout pattern
• a one-sentence rationale for the visual direction

Do not paste the full SVG into chat unless the user explicitly asks for inline code.

Troubleshooting

• If the topic is too broad, ask the user to narrow the angle instead of generating a generic cover.
• If text renders incorrectly, use font-family="Arial, sans-serif" for reliable cross-platform and CJK support.
• If contrast is low, simplify the palette and re-check against the design system guidance.
• If the SVG displays blank in a browser, verify the root namespace, viewBox, and that visible elements are inside the canvas bounds.
• If the user actually wants a scene illustration or raster artwork, hand off to an image-generation skill instead of forcing SVG.

Final Checklist

• Output path is explicit
• Layout choice matches the article angle
• SVG is valid and viewable in a browser
• Title is legible at social-preview scale
