```elixir
@spec generate(PtcRunner.SubAgent.Signature.signature() | nil, map() | nil) ::
  String.t()
```

Generate the expected output section from signature.

Shows the required return format based on the agent's signature,
including field descriptions if available.

## Parameters

- `context_signature` - Parsed signature for return type information
- `field_descriptions` - Optional map of field name atoms to description strings

## Returns

A string containing the expected output section, or empty string if no signature.

## Examples

    iex> sig = {:signature, [{"x", :int}], :int}
    iex> output = PtcRunner.SubAgent.SystemPrompt.Output.generate(sig, nil)
    iex> output =~ "Expected Output"
