• The defaultBranch variable is retrieved but never used in the function. This variable retrieval adds an unnecessary API call. Consider removing the call to getDefaultBranch if the default branch information is not needed, or use it if there's a specific reason (e.g., to validate the repository or include it in logging/reporting).

    const defaultBranch = await getDefaultBranch(octokit, org, repo);
