skilld Auth Login Issue #225

Environment

• OS: Windows 11 Pro 10.0.26300, x64
• Node.js: v24.21.0
• skilld: v3.6.5 (skilld-cli-win32-x64-msvc)
• Shell: PowerShell 5.1 and bash (Git Bash)

Steps to reproduce

1. Run:

   npx skilld auth login

Error

✗ The browser could not open the account login page. (SERVICE_UNAVAILABLE)

No browser opens. Instead, a File Explorer window opens on Documents.

Root cause (likely)

The Windows binary opens the login page by running explorer.exe <url>. The binary contains the literal explorer.exe right next to the the authorization URL must stay on the skilld.dev origin check. That causes two problems:

• When explorer.exe can't parse its argument as a path or URL, it opens the user's Documents folder, which is exactly what happens here. Rust's Command argument quoting doesn't match Explorer's non-standard command-line parsing, especially for URLs containing & or #.
• explorer.exe returns exit code 1 even when it succeeds, so checking its exit status reports a failure every time.

Suggested fix

• Open URLs with ShellExecuteW(NULL, L"open", url, …). The open and webbrowser crates already do this on Windows, as does rundll32 url.dll,FileProtocolHandler <url>.
• Don't use explorer.exe to open URLs, and don't rely on its exit code.

Workaround

npx skilld auth login --no-browser prints the authorization URL so you can open it manually.
