The assignment of last_tool_call.name is duplicated in both branches of the if-else statement. This can be moved outside the conditional block (after line 344) to avoid redundancy.

Suggested change

	{%- set last_tool_call.name = tool_call.name %}
	{%- else %}
	{{- "<|channel|>commentary to=functions." + tool_call.name + " " }}
	{{- (tool_call.content_type if tool_call.content_type is defined else "<|constrain|>json") + "<|message|>" }}
	{%- set last_tool_call.name = tool_call.name %}
