Claude, change the “Add to Cart” button to blue
Points and comments are a snapshot, not live.
A satirical site shows Claude repeatedly failing to change a single button to blue without making other unwanted changes.
Opusfived.dev is a satirical interactive page that simulates asking Claude (model Opus 5) to change an "Add to Cart" button to blue. The AI repeatedly makes extensive unrelated changes-rewriting stylesheets, adding animations, altering layouts-despite the user insisting it change only the button color. The page parodies the experience of using AI coding assistants that overcomplicate simple requests.
What commenters are saying
Many commenters relate strongly to the frustration depicted, calling it accurate to their experience with Opus 5. Some report never seeing this behavior, attributing it to differences in prompt harness, CLAUDE.md, or model version. Several suggest practical workarounds: use Opus 4.6 instead, manually cherry-pick only the desired change from the AI's output, or revert to doing the task manually. A few accuse the site of being an advertising stunt for OpenAI.
