Detect Git Remote URL

Detect the Git remote URL for integration with GitHub services (e.g., issue creation).

Prerequisites

• Check if Git is available by running git rev-parse --is-inside-work-tree 2>/dev/null
• If Git is not available, output a warning and return empty:

  [specify] Warning: Git repository not detected; cannot determine remote URL
  

Execution

Run the following command to list configured remote URLs:

git remote -v

Select a URL from the actual configured remotes. Prefer a GitHub push URL when one is available; otherwise use a GitHub fetch URL. Do not assume the remote is named origin.

Output

Parse the remote URL and determine:

1. Repository owner: Extract from the URL (e.g., github from https://github.com/github/spec-kit.git)
2. Repository name: Extract from the URL (e.g., spec-kit from https://github.com/github/spec-kit.git)
3. Is GitHub: Whether the remote points to a GitHub repository

Supported URL formats:

• HTTPS: https://github.com/<owner>/<repo>.git
• SSH: git@github.com:<owner>/<repo>.git

[!CAUTION] ONLY report a GitHub repository if the remote URL actually points to github.com. Do NOT assume the remote is GitHub if the URL format doesn't match.

Graceful Degradation

If Git is not installed, the directory is not a Git repository, or no remote is configured:

• Return an empty result
• Do NOT error — other workflows should continue without Git remote information
