[BUG] claude remote-control fails: "bad option: --sdk-url"

What's Wrong?

claude remote-control immediately fails on every attempt. The session connects to Anthropic's API briefly, then crashes because --sdk-url is being passed as a Node.js CLI flag instead of being handled internally by Claude Code.
The error occurs on Node.js v24, v22, and v20 — all produce the same result. Regular claude sessions work fine; only remote-control is affected.

What Should Happen?

A Remote Control session should start successfully, displaying a session URL and QR code for connecting from a mobile device or browser.

Additional Information

Additional Information

Tested on three Node.js versions: v24.13.1, v22.22.0, and v20.20.0 — identical error on all
macOS on Apple Silicon (MacBook Air)
Reinstalled Claude Code from scratch (uninstall → cache clean → reinstall) with no effect
Regular claude sessions launch and work correctly
It appears Claude Code is spawning a child process like node --sdk-url <session_id> ..., but --sdk-url is not a valid Node.js flag. This should likely be passed as an application argument after the script path, not as a Node runtime flag.
