What they did
Chang organises a mental health festival in Taipei with 11 speakers. A designer had drawn the key visual; everything after that she made with Claude. She gave it the illustration, two covers by an editorial designer she admired, the speaker sheet and the event links, and asked for a guest line-up, a stage backdrop and on-site material such as tickets, a booklet and signs. Over two days Claude produced speaker cards, share posters, story and LinkedIn images, a magazine spread, event page covers, an event-edition logo and a bilingual, mobile-first website with animated type and flip cards for the speakers, hosted on GitHub Pages with share previews set up.
How it went
The first version ignored the reference style, crammed the type and redrew her animals instead of using them. She pushed back hard and asked Claude to explain the reasoning behind each design choice, which she says helped most. After 46 versions every speaker got a ready-made pack of images labelled by platform, and the site went live. She turned the rules she learned into a Claude skill so the next event takes about two hours.
Worth knowing
Most of the rework came from vague instructions: say what you like about a reference, say the original art must be used as is, and say who will read it and what matters most. The post does not say which Claude surface or plan she used. The skill is public in her repository.
