It looks to me like a variant of the Code Interpreter pattern, where Claude has a (presumably sandboxed) server-side container environment in which it can run Python. When you ask it to make a spreadsheet it runs this:
What's weird is that when you enable it in https://claude.ai/settings/features it automatically disables the old Analysis tool - which used JavaScript running in your browser. For some reason you can have one of those enabled but not both.
The new feature is being described exclusively as a system for creating files though! I'm trying to figure out if that gets used for code analysis too now, in place of the analysis tool.
Odds are the new container and old JavaScript are using the same tool names/parameters. Or, perhaps, they found the tools similar enough that the model got confused having them both explained.
