Unscored: not judged yet
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.
- 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
agentic harness (save the file; self-render allowed), 401 characters. Every result for this prompt
Create an isometric SVG town: first design a small sprite sheet of distinct buildings (in <defs>), then place 20+ of them on an isometric grid with roads, trees, a river and a bridge. Pick your own theme and palette. Save it as town.svg in the current directory. You may render and inspect your own output (headless chromium is available at /usr/bin/chromium) and iterate on your own before finishing.

OpenCode 1.18.32 reported its own total; token counts x list prices shown beside it. The harness reports reasoning tokens separately from output; here output includes them (98,143 visible + 244,934 reasoning), and both bill at the output rate.
