public_github_repository_metric only supports /repos/{owner}

Error message

public_github_repository_metric only supports /repos/{owner}/{repo} URLs

What it means

Thrown by selectGithubRepositoryApiUrl when the URL host/scheme are correct but the pathname does not match /^\/repos\/[A-Za-z0-9_.-]+\/[A-Za-z0-9_.-]+$/. The tool only fetches a single repository resource via the canonical /repos/{owner}/{repo} endpoint; deeper paths, query endpoints, or non-repository paths are rejected to keep the response shape bounded and predictable.

Solutions

1. Use exactly the form /repos/{owner}/{repo} with no trailing slash and no sub-resource path.
2. For sub-resources (issues, releases), do not use this tool; it is scoped to repository-level metrics only.
3. Verify owner/repo segments only contain allowed characters; rename or encode if necessary (encoding is not supported here).

Example fix

// before
input: { url: 'https://api.github.com/repos/octocat/Hello-World/issues' }
// after
input: { url: 'https://api.github.com/repos/octocat/Hello-World' }

const REPO_PATH = /^\/repos\/[A-Za-z0-9_.-]+\/[A-Za-z0-9_.-]+$/;
function assertRepoPath(u: URL): void {
  if (!REPO_PATH.test(u.pathname)) throw new Error('expected /repos/{owner}/{repo}');
}

function isRepoApiUrl(v: unknown): v is string {
  if (typeof v !== 'string') return false;
  try {
    const u = new URL(v);
    return u.protocol === 'https:' && u.hostname === 'api.github.com'
      && /^\/repos\/[A-Za-z0-9_.-]+\/[A-Za-z0-9_.-]+$/.test(u.pathname);
  } catch { return false; }
}

When it happens

Trigger: Pathname is '/repos/octocat' (missing repo), '/repos/octocat/Hello-World/issues' (sub-resource), '/users/octocat' (wrong endpoint), '/repos/foo/bar/' (trailing slash), or contains disallowed characters in owner/repo segments (e.g. spaces, slashes).

Common situations: Model tries to fetch a specific issue or release endpoint by extending the path; developer appends query strings or fragments (these are stripped earlier but path depth still fails); owner or repo contains characters outside [A-Za-z0-9_.-] (rare but possible with renamed/special repos).
