### What problem does this PR solve?
Since `description_list` was a tuple containing a single element (which
was the actual list of descriptions), `len(description_list)` was always
**1**.
The subsequent check:
`if len(description_list) <= 12:` always evaluated to `True` (since $1
\le 12$), even if the inner list contained more than 12 descriptions.
This prevented the necessary summarization logic from running for long
lists.
