• Update the example to reference the correct playbook path (e.g., ansible/mod_config.yml) to match its actual location.

ansible-playbook -i inventory.ini mod_config.yml

ansible/mod_config.yml:9

• [nitpick] Extract the hard-coded paths (/opt/minecraft/config and /home/minecraft/.ssh) into playbook variables (e.g., config_dest_path, ssh_dir) to improve flexibility and reuse.

        path: /opt/minecraft/config

ansible/mod_config.yml:66

• Consider using the ansible.builtin.git module to handle repository initialization, cloning, pulling, and pushing for better idempotence and readability instead of raw git commands.

      ansible.builtin.command: git init -b {{ config_repo_branch }}
