• Draft comment:
  Tuple length mismatch fixed: _create_metrics returns 3 values, so using (None, None, None) is correct when metrics are off.
• Reason this comment was not posted:
  Comment did not seem useful. Confidence is useful = 0% <= threshold 50%

3. packages/opentelemetry-instrumentation-groq/opentelemetry/instrumentation/groq/__init__.py:196

• Draft comment:
  Good cleanup: using multiline conditions and formatting in _set_response_attributes improves readability. The consistent checking of token_histogram is clear.

  None

4. packages/opentelemetry-instrumentation-groq/opentelemetry/instrumentation/groq/__init__.py:575

• Draft comment:
  Tuple unpacking now returns three values instead of four, which aligns with _create_metrics. Verify that the unused 'choice_counter' is intentionally omitted downstream.
• Reason this comment was not posted:
  Comment was not on a location in the diff, so it can't be submitted as a review comment.
