ExitBehavior = Literal['continue', 'error', 'end']How to handle execution when tool call limits are exceeded.
'continue': Block exceeded tools with error messages, let other tools continue
(default)'error': Raise a ToolCallLimitExceededError exception'end': Stop execution immediately, injecting a ToolMessage for each tool call
that exceeded the limit and an AIMessage explaining why. Any other pending tool
call on the same AIMessage (e.g. from parallel tool calling) also gets an
explanatory ToolMessage instead of being executed.
