Design vs Other · both proven

canvas-design vs internal-comms

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. They are in different categories, so this is a choice of job, not a head-to-head on the same job.

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.”

internal-comms

A set of resources to help me write all kinds of internal communications, using the formats that my company likes to use. Claude should use this skill whenever asked to write some sort of internal communications (status reports, leadership updates, 3P updates, company newsletters, FAQs, incident reports, project updates, etc.).

Brief: “Write this week's status update for the Checkout Redesign project as a single HTML page for the leadership channel. Facts to use: the new cart page shipped to 10% of traffic on Tuesday; conversion in the test group is up 2.1% so far; the payments team is two days late on the saved-cards work; a legal review of the new terms copy is still open; launch to 100% is planned for the 30th if the saved-cards work lands by Friday. Keep it short enough to read in a minute.”
