This is much needed!

Compared to Codex CLI, Claude Code is insanely slow.

    $  time claude --version
    2.1.143 (Claude Code)

5 seconds to show me the version number!

I'm guessing Claude Code also needs a rewrite in Rust. But from what I saw in the leaked TypeScript code, a line-to-line port will be pretty bad. It requires a new architecture that matches Rust idioms

Note that includes network requests to check latest version.

I suspect we'll soon see someone make a persistent Claude shell mode, with the reverse of a !, where you work in shell and send a message to Claude, and Claude sees all the context.
