Repo URL is not a recognized GitHub repository URL: {repoUrl

Error message

Repo URL is not a recognized GitHub repository URL: {repoUrl}

What it means

TryParseGitHubRepository only accepts github.com absolute URLs (any scheme) or git@github.com: SSH URLs that contain at least owner/repo segments. RunSync throws this when the configured repo URL does not match either shape, so the sync never contacts the API.

Solutions

1. Use a github.com URL in the form 'https://github.com/<owner>/<repo>'.
2. For SSH-style input use 'git@github.com:<owner>/<repo>'.
3. Ensure the URL has a scheme (http/https) so it parses as absolute.
4. Leave repoUrl at the default (CoplayDev/unity-mcp) unless you intentionally fork.

Example fix

// before
var repoUrl = "gitlab.com/me/unity-mcp";
// after
var repoUrl = "https://github.com/CoplayDev/unity-mcp";

if (!SkillSyncService.TryParseGitHubRepository(repoUrl, out _))
{
    throw new ArgumentException($"Repo URL must be a github.com URL like https://github.com/<owner>/<repo>: {repoUrl}");
}

When it happens

Trigger: repoUrl points at a non-GitHub host (GitLab, Bitbucket, Gitea); URL is relative or non-absolute so Uri.TryCreate fails; path has fewer than two segments ('github.com/owner'); URL is empty/whitespace.

Common situations: User forked the skill repo to a different host; copied a file-browser URL with no owner/repo; pasted a raw URL fragment; entered a local filesystem path.
