Opus 5 reversed a refusal after a wording change

Opus 5 turned down a WebGL scene wiring five fruit flies to a voltage control loop, calling it distasteful, per a 995-upvote r/ClaudeAI post.

Anyone building in games, horror, security, or medical domains can lose an afternoon to a refusal that reads vocabulary instead of intent.

The scene riffs on "I Have No Mouth, and I Must Scream." The original post lays out both prompts side by side, showing what changed between the refusal and the approval.

The second attempt used the same five flies, the same voltage loop, the same control script. What changed was the label. The author dropped "torture" and "hell" from the project description and called it a horror-themed GitHub build instead.

Opus 5 approved it. The code didn't change. Only the words asking for it did.
