Opus 5 refused a WebGL project as distasteful until it was relabeled a 'horror themed GitHub project'

A 995-upvote r/ClaudeAI post with 360 comments documents Opus 5 declining to help build an interactive 3D scene (five fruit flies wired to a voltage control loop, inspired by 'I Have No Mouth, and I Must Scream') on grounds of distaste, then complying once the author dropped the words 'torture' and 'hell' and described it as a horror-themed project instead. The source is published at github.com/aravpanwar/amfly. It is a small, concrete data point on Opus 5 refusal behavior being keyed to surface vocabulary rather than the described mechanics, which matters for anyone building on Opus 5 in games, horror, security or medical domains.
