I figured out a prompting pattern for getting Claude to produce fully self-contained Python scripts that execute with "uv run" using PEP 723 inline script dependencies - and now I can one-shot useful Python utilities with it https://simonwillison.net/2024/Dec/19/one-shot-python-tools/
I have a similar set of custom instructions I use with Claude Artifacts to get it to produce mobile-friendly single page HTML apps that run without a build step
@evan love Web Components - I often prompt it to create those directly, but I still want them all in a single file so I can easily copy and paste the whole lot out of the LLM at once
@evan I use GitHub copilot but I get a ton of work done directly in Claude (with Artifacts) and ChatGPT (with Code Interpeter) pasting code back and forth
