Error message

unable to determine GitHub repo (origin URL not GitHub, and `gh repo view` returned empty)

What it means

When determining which GitHub repository the current directory belongs to, the tool first tries parsing the origin URL; if that is not a GitHub remote it falls back to `gh repo view --json nameWithOwner`. This error is raised when both strategies fail: the origin URL isn't a GitHub URL and `gh repo view` returned an empty string. The tool cannot proceed without knowing the target repo.

Solutions

Set the origin to a GitHub URL: `git remote set-url origin git@github.com:owner/repo.git`
Or make gh resolve it: `gh repo view` manually after `gh auth login`
Run the tool from inside the intended git repository working tree
Add explicit repo configuration to the tool if it supports specifying owner/repo

Example fix

// before
$ git remote -v
origin  https://gitlab.example.com/team/repo.git
Error: unable to determine GitHub repo ...
// after
$ git remote set-url origin https://github.com/owner/repo.git
$ tool create-review  # resolves repo successfully

Defensive patterns

Strategy: validation

Validate before calling

let url = git_remote_url("origin").unwrap_or_default();
let is_github = url.contains("github.com");
let gh_repo = Command::new("gh")
    .args(["repo", "view", "--json", "nameWithOwner",
           "--jq", ".nameWithOwner"])
    .output()?;
if !is_github && gh_repo.stdout.trim().is_empty() {
    return Err(anyhow!("set a GitHub origin or authenticate gh first"));
}

Try / catch

if let Err(e) = result {
    if e.to_string().contains("unable to determine GitHub repo") {
        eprintln!("fix `git remote set-url origin <github url>` or `gh auth login`");
    }
    return Err(e);
}

Prevention

Ensure origin points at github.com before running GitHub-dependent flows
Authenticate gh (`gh auth login`) so `gh repo view` can resolve repos
Run the tool inside a git work tree with a configured remote
Validate `git remote -v` output in project setup scripts

When it happens

Trigger: `resolve_github_repo()` gets an empty trimmed result from `gh repo view --json owner.name --jq .nameWithOwner`, i.e. origin is not a GitHub URL AND gh cannot infer the repo from the directory.

Common situations: Repo whose origin points to GitLab/Bitbucket/self-hosted git; detached directory with no remote; gh not authenticated in a way that lets it resolve `repo view` without a remote; running from a subdirectory of a non-git folder.
