# Update Browserbase agent

> Change a reusable browser agent's defaults.

`browserbase.updateAgent` changes a reusable browser agent's defaults. Inputs accept literal values or compatible signals. An optional second argument `{ account }` selects a named Browserbase binding.

## Example

```ts theme={null}
import { automation, onInvocation } from "automate.ax"
import { browserbase } from "automate.ax/browserbase"

export default automation("Update Browserbase agent", () => {
  onInvocation()
  browserbase.updateAgent({
    agentId: "agent-id",
    systemPrompt: "Use official sources.",
  })
})
```
