Resource: quick LLM sandboxing

I want to share an interesting pattern – get claude code on the web (or any other autonomous agent + sandbox) to do R&D on a coding question. Based on these blog posts – https://simonwillison.net/2026/Feb/6/pydantic-monty/ and https://simonwillison.net/2025/Nov/6/async-code-research/. I wanted to learn about WASM and Pyodide as I don’t know much about these technologies. I asked Claude code on the web to do the following “I want to learn about WASM and pyodide, read this great blog post and then create a /tutorial dir that contains all of the resources needed for serving a pyodide-wasm-tutorial.html files, it will be served by GitHub Pages so they can load the WASM and wheel from a relative path since the .html files will be served from the same folder as the wheel and WASM file. I know a lot about python but little about these tools.”, then I pointed it at the first of those blog posts. After a few minutes it created a PR into one of my repos in Github, and after turning on github pages I am able to now learn about those technologies in this mini tutorial https://ian-bmj.github.io/bmj-ai-rapid-prototype/tutorial/pyodide-wasm-tutorial.html
