Generated scripts can consume CPU or navigate their own frame. Curator review is required. Stop cannot reliably recover a blocked browser.
Curator's read
What stands out
A detailed read of this attempt's approach, distinctive choices, and lessons for future runs.
- Reproduced zero-tool one-shot raw HTML output inside the coding-agent harness with 59% fewer thinking tokens (2,136 vs. 5,200), while syncing foreground canvas exhaust particles to the transformed SVG hoverboard via per-frame getBoundingClientRect() queries and adding a collectible highway yuzu loop.
