| Parameter      | Type                                                                                    | Default                                       | Description                                                         |

## HumanReview configuration [#humanreview-configuration]

Pass these settings inside `human_review=HumanReview(...)`. They are not direct constructor arguments. See [HumanReview](/workflows/hitl/human-review) for the complete configuration and supported combinations.

| Parameter               | Type                   | Default         | Description                                                                                                                        |
| ----------------------- | ---------------------- | --------------- | ---------------------------------------------------------------------------------------------------------------------------------- |
| `requires_confirmation` | `bool`                 | `False`         | Pause before evaluating the condition. Approval evaluates `evaluator`; rejection follows `on_reject`                               |
| `confirmation_message`  | `Optional[str]`        | `None`          | Message shown to user when requesting decision                                                                                     |
| `on_reject`             | `Union[OnReject, str]` | `OnReject.skip` | Action when rejected: `OnReject.else_branch` (execute else\_steps; raw string value `"else"`), `skip`, `cancel`                    |
| `on_error`              | `Union[OnError, str]`  | `OnError.skip`  | Action when a sub-step fails: `skip` (log and stop remaining sub-steps), `fail` (re-raise), `pause` (pause for HITL retry or skip) |

When `human_review` is omitted, `Condition` creates `HumanReview(on_reject=OnReject.else_branch)`. An explicitly supplied `HumanReview()` uses its own `OnReject.skip` default. Set `on_reject=OnReject.else_branch` explicitly when rejection should run `else_steps`.

Constructor example (install `agno` first):

```python
from agno.workflow.condition import Condition
from agno.workflow.step import Step
from agno.workflow.types import HumanReview, StepInput, StepOutput, OnReject

def prepare(step_input: StepInput) -> StepOutput:
    return StepOutput(content=step_input.input)

prepare_step = Step(name="prepare", executor=prepare)
step = Condition(
    steps=[prepare_step], evaluator=True,
    human_review=HumanReview(requires_confirmation=True, on_reject=OnReject.else_branch),
)
```
