# Overview

> Learn about built-in browser actions and custom tools.

## Quick Example

```python theme={null}
from browser_use import Agent, Tools, ActionResult, BrowserSession

tools = Tools()

@tools.action('Ask human for help with a question')
async def ask_human(question: str, browser_session: BrowserSession) -> ActionResult:
    answer = input(f'{question} > ')
    return ActionResult(extracted_content=f'The human responded with: {answer}')

agent = Agent(
    task='Ask human for help',
    llm=llm,
    tools=tools,
)
```

<Warning>
  **Important**: The parameter must be named exactly `browser_session` with type `BrowserSession` (not `browser: Browser`).
  The agent injects parameters by name matching, so using the wrong name will cause your tool to fail silently.
</Warning>

<Note>
  Use `browser_session` parameter in tools for deterministic [Actor](/open-source/legacy/actor/basics) actions.
