description: Sign in to Grok Build for the native harness.
disable-model-invocation: true
allowed-tools: Bash
---
Tell the user to run the official Grok Build sign-in in their own terminal:
+ Linux/macOS (POSIX shell):
+
```sh
"$HOME/.local/share/multi-cli/bin/multi" login grok
```
- This hands off to `grok login`, which opens the browser flow, or
- `grok login --device-auth` on a headless host. Check `/multi-usage` first: it
- reports whether a renewable login is already present, in which case no sign-in is
- needed. Tell the user that they must relaunch Claude afterward to load the Grok
+ Windows PowerShell:
+
+ ```powershell
+ & "$HOME/.local/share/multi-cli/bin/multi.cmd" login grok
+ ```
+
+ Windows cmd:
+
+ ```bat
+ "%USERPROFILE%\.local\share\multi-cli\bin\multi.cmd" login grok
+ ```
+
+ Use the command for the target shell; Windows installs `.cmd` and `.ps1` shims,
+ not an extensionless executable.
+
+ This helper invokes `grok login` without additional arguments; it does not select
+ a device flow. For headless sign-in, use the installed CLI's `grok login --help`
+ and run its supported flow directly in the user's terminal.
+ `/multi-usage` can report local credential presence, but a refresh token does not
+ prove the provider still accepts the login. Follow the CLI's authentication result.
+ Tell the user to relaunch Claude after a successful login to load the Grok
rows. Never accept, request, read, or print credentials in chat; native
credentials remain owned by `grok`.
