Notes
Claude Code install is the example-skills plugin from anthropics/skills, which also adds algorithmic-art and other skills. In Codex, copy the canvas-design folder into ~/.agents/skills or a repo's .agents/skills. The agent writes a .md philosophy, then draws a .png or .pdf with code and the bundled fonts. It calls no image model, so no API key or credits. The skill tells the agent to make original work and not copy existing artists.
