Defined in:

Overview

MessageTransport for the llm.rb gem (https://github.com/llmrb/llm.rb). Brute does not require llm.rb — you do:

require "llm"

llm = LLM.openai(key: ENV["OPENAI_API_KEY"])
messages = Brute::MessageTransport::LLM.dump_all(env[:messages])
response = llm.complete(messages.pop, role: nil, messages: messages, tools: ...)
Brute::MessageTransport::LLM.wrap_each(response) { |m| env[:messages] << m }

Class Method Details

.dump(message) ⇒ Object

Brute::Message -> LLM::Message. Assistant tool calls carry llm.rb's original_tool_calls extra (the provider wire format); tool results become an LLM::Function::Return so llm.rb's request adapters emit them correctly.
