[BUG] `chat.ask(query).tool_calls` empty

[KieranP]

Basic checks

• I searched existing issues - this hasn't been reported
• I can reproduce this consistently
• This is a RubyLLM bug, not my application code

What's broken?

We use Mongoid, so can't use built in ActiveRecord support for storing chats.

Part of this, I need to store the final response. But tool calls aren't included (response.tool_calls is empty hash even tough I know it is making tool calls to the DB because it can return the info it should).

Am I missing something? Shouldn't the response returned by ask include all tools made during the execution of ask?

How to reproduce

Basic setup with a tool:

response = chat.ask(query)
puts response.tool_calls.inspect

Expected behavior

Response from chat.ask should include all tool calls made

What actually happened

Tool calls is empty

Environment

Ruby 3.4.1
RubyLLM: 1.12.0
Provider: Bedrock

Looks like this might be intentional design? I am working around it for now by doing this:

existing_message_size = chat.messages.size

response = chat.ask(query)

new_messages = chat.messages[existing_message_size..-1]

new_messages gives me all the messages including the ones with tool calls.
