prompt = """TASK: Implement streaming support for the DeepSeek provider in ai_client.py and add failing tests.

INSTRUCTIONS:
1. In @tests/test_deepseek_provider.py: 
   - Add a test function 'test_deepseek_streaming' that mocks a streaming API response using 'requests.post(..., stream=True)'.
   - Use 'mock_response.iter_lines()' to simulate chunks of data.
   - Assert that 'ai_client.send()' correctly aggregates these chunks into a single string.

2. In @ai_client.py:
   - Modify the '_send_deepseek' function to use 'requests.post(..., stream=True)'.
   - Implement a loop to iterate over the response lines using 'iter_lines()'.
   - Aggregate the content from each chunk.
   - Ensure the aggregated content is added to the history and returned by the function.

OUTPUT: Provide the raw Python code for the modified sections or the full files. No pleasantries."""
