claude-code - 💡(How to fix) Fix /terminal-setup rejects Windows Terminal despite suggesting it [2 comments, 2 participants]

The error message tells the user to run the command in Windows Terminal — which is exactly where they already are. "windows-terminal" is not in this list, so hCH() returns false and the error branch runs. The error branch then detects platform === "windows" and helpfully suggests "Windows: Windows Terminal" — creating a contradictory message. 2. Remove the misleading suggestion — don't suggest "Windows: Windows Terminal" in the error message if it's not actually supported

TL;DR

To fix the issue, modify the hCH() function to include "windows-terminal" in the allowed terminals list and add a corresponding handler in Ci8() for Windows Terminal setup.

Guidance

• Identify the hCH() function in the claude.exe binary and modify it to include "windows-terminal" in the conditional statement to allow setup to proceed.
• Add a new case handler in the Ci8() function to configure the Shift+Enter keybinding for Windows Terminal, utilizing its custom keybinding feature via settings.json.
• Verify that the terminal is correctly detected as windows-terminal and that the modified hCH() function returns true for this terminal.
• Test the setup process in Windows Terminal after applying the modifications to ensure it works as expected.

Example

function hCH() {
    return bt.platform() === "darwin" && M$.terminal === "Apple_Terminal"
        || M$.terminal === "vscode"
        || M$.terminal === "cursor"
        || M$.terminal === "windsurf"
        || M$.terminal === "alacritty"
        || M$.terminal === "zed"
        || M$.terminal === "windows-terminal" // Add this line
}

Notes

The provided solution assumes that the claude.exe binary can be modified. If this is not possible, an alternative approach would be to request an update to the binary that includes the necessary modifications.

Recommendation

Apply the workaround by modifying the hCH() function and adding a new case handler in Ci8() to support Windows Terminal, as this will allow the setup process to work correctly in the current environment.
