### Implementation notes

Split entered payments and shared expenses evenly among named travellers. It does not create payment transfers.

### Inputs and settings

Text input: JSON input.

Example or placeholder shown in the interface (not a validated fixture):

```text
{
  "people": [
    {
      "name": "A",
      "paid": 100
    },
    {
      "name": "B",
      "paid": 0
    }
  ],
  "sharedExpenses": 0
}
```

Use the documented fields. Up to 200,000 characters. Review the settings before running.

No additional settings are declared for this tool.

### Browser-agent workflow

1. Open the human page in a browser that supports WebMCP.
2. Discover the interface exposed by that page; use its actual schema.
3. Select files on the page first when the tool requires files.
4. Call `run_current_tool` with valid input and settings.
5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.

Calls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.

### Planning specification

Bounded browser-local calculations with complete JSON and printable HTML output.

This describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.
