openai.internal._chat_tool_args

(internal) A tool call's `arguments` is a JSON *string* the model produced, so it can be malformed (a truncated call, a model that emitted prose). Degrading to `{}` would hand the runner an empty-argument invocation of a real tool and tell nobody the arguments were discarded, so an undecodable payload is a `ParseFailed` carrying the raw string.
