### TOOL_CALL Chunks
Information about tool calls being made:
Information about tool calls being made. Depending on the provider, CrewAI may receive tool-call arguments incrementally. In that case, each `TOOL_CALL` chunk contains the latest streamed content in `chunk.content`, while `chunk.tool_call.arguments` contains the accumulated argument string so far.
```python Code
for chunk in streaming:
if chunk.chunk_type == StreamChunkType.TOOL_CALL:
print(f"\nCalling tool: {chunk.tool_call.tool_name}")
print(f"Arguments: {chunk.tool_call.arguments}")
print(f"Latest argument delta: {chunk.content}")
print(f"Arguments so far: {chunk.tool_call.arguments}")
```
Actual tool execution is reported separately through tool usage events in the runtime event stream and through CrewAI's verbose console output. `TOOL_CALL` chunks represent the model constructing the tool request before or during execution.
