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. Tap inside for sound.

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, 2,012 characters. Every result for this prompt
Build a working code editor in one page in the spirit of a lightweight VS Code. It needs: a file explorer sidebar with a small seeded project (index.html, style.css, app.js, utils.js, README.md) where files can be created, renamed and deleted; tabs for open files with unsaved-change dots; an editor component you write yourself (no libraries) with line numbers, syntax highlighting for JavaScript, CSS, HTML and Markdown, auto-indent, bracket matching and auto-closing, multi-line indent and outdent of selected lines from the keyboard, current-line highlight, and a minimap; find and replace with match count and regex toggle; a command palette (Ctrl+Shift+P) with fuzzy search over commands and files; a run button that executes app.js in a sandboxed iframe with the project's HTML and CSS and shows its output plus console logs and errors in a bottom panel; light and dark themes; and persistence of the whole project to localStorage. So the page is alive without input, on load it runs a scripted demo: the cursor opens app.js, types a small function character by character with realistic pauses, autocloses brackets, uses find and replace to rename a variable, opens the command palette, runs the project so a little animation appears in the preview and a log line in the console, then reverts and repeats with a different snippet, until the user touches anything. Make it feel fast and professional. Save it as index.html in the current directory: one self-contained file with inline CSS and JavaScript only, no libraries or frameworks, and no external requests of any kind (no CDNs, web fonts, images or audio files). It must work when opened directly from disk, fit any window from a 390 px wide phone to a desktop, and run without console errors. You may serve it locally and open it in headless chromium (/usr/bin/chromium, software WebGL, no GPU) to screenshot and inspect your own output, and iterate on your own before finishing. Close any browser you open as soon as you've taken your screenshot.

Cost breakdown
No cost figure: the run's tokens were never reported, so there is nothing to estimate from.
| Tokens by type | Tokens | $ per 1M | Cost |

| Cache write | 215,317 | n/a | n/a |
| Cache read | 3,038,129 | n/a | n/a |
| Output | 189,297 | n/a | n/a |
- Total computed from tokens
- unknown
- Total reported by the harness
- none
No harness total and no complete list-price estimate. No list price for claude-sonnet-5-5 in config/prices.json; no estimate computed.
Run notes
- frozen prompt (written): written 2026-10-05 for the MR category expansion (owner request: 500 finished runs in every category); category app_clones; zero results
- plain wave-1-equivalent cc_config copy (settings.json + .claude.json; no ECC files)
- Mode: interactive TUI in tmux (160x48), inside bubblewrap sandbox
- Context setting: Claude Code default 200k context
- Isolation audit: outside paths seen
- Renderer: inline SVG (first <svg> at index.html line 356) plus an HTML5 2D canvas (getContext('2d') at index.html line 770) in one self-contained HTML file; no libraries, no CDN, no external assets. No WebGPU or WebGL needed.
- The published copy renames one CSS custom property (the words tab and bar written as one word) to "tab-bar" (3 occurrences, CSS only, no script use) to pass the site's banned-string gate; nothing else is changed.
- Card video: the run's own video.mp4 (H.264 yuv420p, unchanged). Poster: the run's own render.png.
- Same frozen prompt as the other rows on this test; configurations differ and all rows are unscored, so this is not a head-to-head result.
