# output

The step-level `output` field overrides the workflow-level [output](/workflows/output) mode for a single step.

```yaml
workflows:
  verbose-deploy:
    output: log
    steps:
      - name: plan
        type: atmos
        command: terraform plan vpc
        output: viewport
        viewport:
          height: 4
          padding: 2
```

A live viewport follows recent stdout and stderr, collapses on success, and reveals
full output on failure. See [live viewport](/workflows/output#live-viewport) for sizing
and noninteractive behavior.

Supported values are `raw`, `log`, `viewport`, and `none`. See workflow-level [output](/workflows/output) for the value definitions. Any other value, such as `capture`, fails validation before the step runs, and the error lists the valid modes. This applies to `shell`, `script`, `atmos`, and `container` steps and to the workflow-level `output`.

Terminal-handoff steps such as `tty`, `interactive`, and `exec` own the terminal while they run, so normal output capture modes do not apply in the same way.
