 | `github` | `object` | The top-level context available during any job or step in a workflow. This object contains all the properties listed below. |
 | `github.action` | `string` | The name of the action currently running, or the [`id`](/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idstepsid) of a step. {% data variables.product.prodname_dotcom %} removes special characters, and uses the name `__run` when the current step runs a script without an `id`. If you use the same action more than once in the same job, the name will include a suffix with the sequence number with underscore before it. For example, the first script you run will have the name `__run`, and the second script will be named `__run_2`. Similarly, the second invocation of `actions/checkout` will be `actionscheckout2`. |

You can use this path to access files located in the same repository as the action, for example by changing directories to the path: {% raw %} `cd ${{ github.action_path }}` {% endraw %}. |
