My simonw/research GitHub repo is deliberately separate from everything else I do because it's entirely AI-generated. I wrote about that here: https://simonwillison.net/2025/Nov/6/async-code-research/#th...
This particular case is a very solid use-case for that approach though. There are a ton of important questions to answer: can it run in WebAssembly? What's the difference to regular JavaScript? Is it safe to use as a sandbox against attacks like the regex thing?
Those questions can be answered by having Claude Code crunch along, produce and execute a couple of dozen files of code and report back on the results.
I think the knee-jerk reaction pushing back against this is understandable. I'd encourage people not to miss out on the substance.
