gh pr create failed

Error message

gh pr create failed: {stderr}

What it means

create_draft_pr_with_gh runs `gh pr create` inside the worktree to open a draft pull request. When gh exits nonzero, the library bails with gh's stderr so the GitHub-side failure (GraphQL error, missing auth, invalid base, etc.) is visible in the message.

Solutions

1. Read the stderr in the message — gh prints the exact GitHub API error.
2. Run `gh auth status` in the worktree environment and authenticate (GH_TOKEN or `gh auth login`).
3. Verify the base branch and any labels/reviewers exist on the remote before calling.
4. Check for an existing open PR for the branch (`gh pr list --head <branch>`).
5. Update the gh CLI if the error mentions an unknown flag.

let auth = Command::new("gh").args(["auth", "status"]).output()?;
if !auth.status.success() { eprintln!("gh not authenticated"); }

match create_draft_pr(&wt, title, body) {
    Ok(url) => println!("draft PR: {url}"),
    Err(e) if e.to_string().contains("already exists") => eprintln!("PR already open"),
    Err(e) if e.to_string().contains("auth") => eprintln!("run: gh auth login or set GH_TOKEN"),
    Err(e) => return Err(e),
}

When it happens

Trigger: Calling create_draft_pr when `gh` is unauthenticated, the base branch named in DraftPrOptions does not exist on the remote, the branch is already covered by an open PR, GitHub returns a validation error, or gh CLI is a version lacking a used flag.

Common situations: CI without `gh auth login` / GH_TOKEN set; typo'd custom base branch or nonexistent labels/reviewers passed in options; `draft PR already exists` after a retry; corporate proxy blocking api.github.com.
