Module: OpenTelemetry::Instrumentation::RubyLLM::MessageFormatter

Defined in:
lib/opentelemetry/instrumentation/ruby_llm/message_formatter.rb

Overview

Converts RubyLLM messages and content into the JSON shape defined by the GenAI semantic conventions for input/output messages and system instructions:

https://github.com/open-telemetry/semantic-conventions-genai/blob/main/docs/gen-ai/gen-ai-input-messages.json
https://github.com/open-telemetry/semantic-conventions-genai/blob/main/docs/gen-ai/gen-ai-output-messages.json
https://github.com/open-telemetry/semantic-conventions-genai/blob/main/docs/gen-ai/gen-ai-system-instructions.json

Kept separate from the RubyLLM::Chat patch so the formatting logic does not pollute the patched class.
