Two design skills · both proven

algorithmic-art vs canvas-design

Both skills were run through Claude twice: once on a fixed brief without the skill, once with it. The briefs differ because each is written for the job the skill claims to do, so compare each skill against its own baseline, then decide which difference matters for your work.

algorithmic-art

Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.

Brief: “Make a generative art piece called Tidewater: a single HTML page with a full-window canvas that draws slow, layered flow-field lines in a deep sea palette, seeded so the same seed always gives the same picture. Include a small control panel to change the seed, the line density and the palette, and a button to save the current frame as a PNG. Use p5.js from a CDN.”

canvas-design

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.

Brief: “Build the one-page site for Blue Hour, a monthly jazz night at a small club: a poster-style hero with a drawn inline SVG illustration, the lineup with short bios, the schedule, a photo-strip section drawn with SVG, ticket tiers, and a footer with the address. Make it feel like a printed poster brought to the web, with motion.”
