[Language reference](/reference/language/overview) / `outputs`

## Meaning and placement

### document

The workflow's return value · symmetric to inputs. Each entry is a `${{ tasks.X.output }}` reference (untyped form · string) OR a typed declaration \{ value · type · description }. Powers `nika run` result + the output half of the callable-workflow schema.

## In a source template

Excerpt from `templates/agent-loop.nika.yaml`, source lines 142–148. This is a fragment, not a runnable workflow.

```yaml illustration theme={"system"}
        condition: "${{ with.has_findings }}"
        message: "Agent returned no findings, do not trust an empty run"   # SLOT

outputs:
  findings:
    value: ${{ tasks.execute.output.findings }}
    description: "The agent's typed findings"   # SLOT
```
