 | `commit_prefix`           | No       | `""`             | Prefix added to commit message. Combines with `commit_message`.                                                                                               |
 | `commit_message`          | No       | `""`             | Commit message to set. Combines with `commit_prefix`. Can be used with `amend` to change the commit message.                                                  |
 | `user_name`               | No       | `""`             | Git `user.name` used for created commits. Defaults to `${{ github.actor }}` when empty.                                                                       |
-| `user_email`              | No       | `""`             | Git `user.email` used for created commits. Defaults to `${{ github.actor }}@users.noreply.<organization_domain>` when empty.                                 |

 | `signing_mode`            | No       | `""`             | Commit signing mode. Supported values are `gpg` and `ssh`. Leave empty to disable signing.                                                                    |
-| `signing_key`             | No       | `""`             | Signing key material. For `gpg`, provide an ASCII-armored private key export. For `ssh`, provide a private key in OpenSSH or PEM format.                     |

 | `signing_passphrase`      | No       | `""`             | Optional passphrase for the signing key. Passphrase-protected GPG keys are supported. Encrypted SSH signing keys are rejected in the current runtime.         |
 | `force`                   | No       | `false`          | Whether to use force push (`--force`). Use only when you need to overwrite remote changes. Potentially dangerous.                                             |
 | `force_with_lease`        | No       | `false`          | Whether to use force push with lease (`--force-with-lease`). Safer than `force` as it checks for remote changes. Set `fetch-depth: 0` for `actions/checkout`. |
