Error message

failed to open browser

What it means

`open_in_browser` (src/commit.rs:8927) on macOS runs `open <url>`; if the spawned process exits non-zero this bail reports the URL could not be opened in the system browser.

Solutions

1. Set a valid default browser in macOS System Settings > Desktop & Dock > Default web browser.
2. Test `open <url>` in a terminal to confirm the environment can open URLs.
3. Run in a GUI session instead of headless/SSH/CI, or use the PR URL already printed.
4. Verify `/usr/bin/open` works (`open -a 'Safari' <url>`).

let check = Command::new("open").arg("-g").arg("https://example.com").status();
if check.map(|s| !s.success()).unwrap_or(true) {
    eprintln!("`open` cannot launch a browser; print the URL instead");
}

fn can_open_browser() -> bool {
    Command::new("open").arg("-g").arg("https://example.com")
        .output().map(|o| o.status.success()).unwrap_or(false)
}

if let Err(e) = open_in_browser(&url) {
    eprintln!("could not open browser ({e}); open this URL manually:\n{url}");
    // do not fail the whole PR-creation flow because browser launch failed
}

When it happens

Trigger: `Command::new("open").arg(url).status()` spawns successfully but `open` returns non-zero: no default browser set, Launch Services failure, dangling default handler after a browser uninstall, or headless/sandboxed macOS environment.

Common situations: CI runner or SSH session on a Mac with no GUI session; default-browser registration pointing at an uninstalled app; container/sandbox where LaunchServices is unavailable.
