ChatAnthropic incorrectly routes the documented browser_toolset_20260801 client toolset through JSON-schema conversion, raising ValueError. Non-null toolset_name on tool_use blocks is lost in multi-turn requests, and ordinary tool calls expose toolset_name=None.
When PIIMiddleware is configured with apply_to_output=True and the model streams tool call arguments in multiple chunks, the streaming redaction path treats each chunk's args fragment as complete JSON. Since each fragment is an invalid JSON string, the redactor returns an empty value, causing all tool call arguments to be erased. This leads to tool execution with no arguments and eventually a GraphRecursionError.
