Overview

What it does

Claude first writes a design philosophy of four to six paragraphs, saved as a Markdown file, and then expresses it on a canvas with code. The instructions push for original, museum-quality work and explicitly against copying existing artists.

The folder carries about thirty open-licence font families in canvas-fonts/, most with their SIL Open Font Licence file alongside, so designs aren’t limited to system fonts. A multi-page option produces a set of related designs.

Triggers

When Claude uses it

  • Requests for a poster, a piece of art, a design or another static visual piece.
Its description, which Claude matches against
Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.

What it needs

  • A code environment that can draw a PNG or PDF (SKILL.md doesn’t name a library); the fonts are bundled.

Install

How to install it

Claude Code

Plugin (type in Claude Code)
/plugin marketplace add anthropics/skills
/plugin install example-skills@anthropic-agent-skills

The example-skills plugin installs 12 skills from this repository, including this one. Its skills are then namespaced, such as /example-skills:canvas-design.

Or copy the folder (shell)
git clone --depth 1 https://github.com/anthropics/skills.git
mkdir -p ~/.claude/skills
cp -r skills/skills/canvas-design ~/.claude/skills/

That makes it a personal skill, available as /canvas-design in all your projects. Copy it into .claude/skills/ in a repository instead to share it with your team.
