The --list-tasks command line option can be used to output the tasks that would have been invoked in a playbook.

ansible-playbook example.yml --list-tasks

Which should return something like this. Notice the output includes tags. Refer to Ansible - Getting Started with Tags to understand tags.

playbook: example.yml

  play #1 (all): all TAGS: []
    tasks:
      name of your first task  TAGS: []
      name of your second task  TAGS: []
      name of your third task  TAGS: []
