Claude Opus 5.5
The model answered with a p5.js sketch, as asked. We run it unchanged in a page that loads p5.js, the way the p5.js editor does. Click the panel to engage the fold drive.
Test conditions
One attempt per test, with no edits after running. Where a first attempt didn’t work, the test was answered once more and the exhibit says so; answers that still don’t work are not shown. Run inside a Claude Code agent session, which includes its own system prompt, rather than the raw API.
