Fix status: documented_behavior Other error fragments: - Sorbet structured-output function tools are not supported - Sorbet structured outputs require the optional sorbet-runtime gem Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/openai/openai-ruby/6f786c6a752a0a2773ecf7c1b0b4490a94104c15/lib/openai/helpers/sorbet.rb (official_docs, unknown, documented_behavior): Raises these ArgumentErrors for streaming and function-tool use, and LoadError when sorbet-runtime is missing. - https://raw.githubusercontent.com/openai/openai-ruby/6f786c6a752a0a2773ecf7c1b0b4490a94104c15/README.md (official_docs, unknown, documented_behavior): README: integration supports non-streaming responses.create and chat.completions.create only; streaming structured outputs and function-tool schemas are not supported.
