## Quick Example
```python
from browser_use import Tools, ActionResult, Browser
tools = Tools()
@tools.action('Ask human for help with a question')
def ask_human(question: str, browser: Browser) -> ActionResult:
answer = input(f'{question} > ')
return f'The human responded with: {answer}'
agent = Agent(
task='Ask human for help',
llm=llm,
tools=tools,
)
```
<Note>
Use `browser` parameter in tools for deterministic [Actor](/customize/actor/basics) actions.
