I don't think this is a bug specifically with Claude Code, rather it's due to Claude Code having javascript in the backend. The interesting thing to me is that the numeric string was interpreted as an integer.

I agree with what I think you meant: it is not a bug in Claude. However "javascript on the backend" is exactly what Claude Code is! It's a node.js implementation of automation components that feed and pull from the Claude model.

I have a VERY hard time believing that they only use JSON serialization between the model and the TUI. If they're seriealizing JSON between agents, tools, or other components, then this problem is going to continue to persist for a very long time.
