StructuredOutput gets in a loop #775
Description
Sometimes I have that StructuredOutput gets in a loop where it keeps trying to correct itself. It basically goes like this:
AssistantMessage(content=[TextBlock(text='<StructuredOutput>\n<parameter name="found_useful_information">false</parameter>\n<parameter name="answer">answertext</parameter>\n<parameter name="sources">[]</parameter>\n</StructuredOutput>')], model='claude-sonnet-4-6'....
UserMessage(content=[TextBlock(text='Stop hook feedback:\nYou MUST call the StructuredOutput tool to complete this request. Call this tool now.')], uuid='191538a1-0dd7-415c-a728-50165282a087', parent_tool_use_id=None, tool_use_result=None)
And then it just keeps repeating the same pattern, it never calls the StructuredOutput tool, it just keeps on trying this odd <StructuredOutput> type of text output. It somehow thinks that using <StructuredOutput> is the same thing as calling it?
It also gets stuck inside this loop for WAY too long (basically until it hit the max budget), this should be restricted somehow.
