Claude Sonnet 5.5 in Claude Code 2.1.280
skills off
Zoom, inline player and more ways to view
The model's own page, run in a sandboxed frame only when you ask (a page that needs its own origin opens in a new tab on a separate demo site). Phones get a full-screen player capped at 1.5x pixel density (2x on larger screens) so it stays smooth; the original page runs uncapped. It starts in its auto-tour (T switches to play mode on a keyboard).

Scores

Not scored
No rubric for this prompt
Visitor votes and reviewer grades are not available yet.
- AI judge
- AI judge: the test runner (model claude-opus-5-5), scoring by visual review of the 1600 px render against the pre-registered rubric. No AI-judge score exists for this result: there is no rubric for this prompt, so no score is shown and none is made up.
- Visitors
- Public voting with a blind reveal is coming: you score the output first, then see the other scores.
- Reviewer
- The reviewer's own grade appears here once it is added.
Scores compare results for the same prompt only. AI-judge boards rank runs within one prompt, equal totals sharing a rank; scores from different prompts are never averaged.

The exact prompt
as run, 971 characters. Every result for this prompt
Design a giant desert sandworm re-engineered as a robot, presented as an engineering blueprint. Deliver ONE self-contained index.html (SVG and/or canvas, inline CSS and JS, no external assets, libraries or fonts). It must include: an animated robotic worm that moves through sand, with segments that articulate as it burrows and surfaces; a labelled segment-by-segment mechanical breakdown (for example head and mouth assembly, drive segments, sensor ring, power core, tail) with callouts naming each part and what it does; a cross-section diagram of the mouth showing the grinding and intake mechanism; and a terrain and operations map showing the worm's route, depth and working zones. Everything must share one cohesive blueprint style: blueprint-blue background, white and cyan line work, grid, dimension lines, title block and technical lettering. It must look good on desktop and phone. Write everything into the working directory and finish with a short README.md.
