I think you’re confusing capital c Claude Code, the desktop Electron app, and lowercase c `claude`, the command line tool with an interactive TUI. They’re both TypeScript under the hood, but the latter is React + Ink rendered into the terminal.

The redraw glitches you’re referring to are actually signs of what I consider to be a pretty major feature, a reason to use `claude` instead of `codex` or `opencode`: `claude` doesn’t use the alternate screen, whereas the other two do. Meaning that it uses the standard screen buffer, meaning that your chat history is in the terminal (or multiplexer) scrollback. I much prefer that, and I totally get why they’ve put so much effort into getting it to work well.

In that context handling SIGWINCH has some issues and trickiness. Well worth the tradeoff, imo.

Anthropic needs to spend some tokens rewriting Claude Code in Rust (yes, really).

The difference in feel between Codex and Claude Code is obvious.

The whole thing is vibed anyway, I'm sure they could get it done in a week or two for their quality standards.

Totally agree. I'm baffled by those who don't clearly see that Codex works better than C.C. in many ways.
