The variable isMultipleNativeToolCallsEnabled is declared here but never used anywhere in this function. This appears to be dead code. The parallel tool call behavior is controlled by parallelToolCalls in Task.ts (which is passed to the API metadata), but this variable in presentAssistantMessage.ts doesn't modify any behavior - the didAlreadyUseTool check at line 436 will still reject all but the first tool even when this experiment is enabled. If this variable was intended to control execution of multiple tools, the implementation appears incomplete. Consider removing this dead code.

Fix it with Roo Code or mention @roomote and request a fix.
