Mistral-large generates code blocks that are not detected by the regex.
Although they have <code> or python <code> structure.
Maybe some requirements can be relaxed.

Suggested more relaxed regex: r'(?:\w+)?\n?(.*?)\n?'

Example for a non-detected code block:

# Step 1: Use the Milvus retriever tool to find information about the song featured in the movie Hamrahi
results = _milvus_retriever_tool_dataset(query="song featured in the movie Hamrahi")

# Step 2: Print the results to see if we can find the name of the song
print(results)
