Get retries working again despite prefix

[simonw]

I found a query that gave a SQL parse error first time and needed a retry and got this error:

anthropic.BadRequestError: Error code: 400 - {'type': 'error', 'error': {'type': 'invalid_request_error', 'message': 'messages: roles must alternate between "user" and "assistant", but found multiple "assistant" roles in a row'}}

I upgraded to Sonnet for this experiment. The question I tried was:

4 most popular licenses and the top repos for each one, use json_object

Against the https://datasette.io/content/licenses table

Eventually got it working. The debug output looked like this:

--
explain select l.name, l.key, json_group_object (
    'repos', json_group_array(
        json_object(
            'id', r.id,
            'full_name', r.full_name,
            'stargazers', r.stargazers_count
        )
    )
)
from licenses l
join repos r on r.license = l.key
group by l.name, l.key
order by sum(r.stargazers_count) desc
limit 4;
