Mostly looks good.

Please:

1. Setup the code to print the wikipedia URLs everywhere we print wikipedia text
2. Where we print the final answer, list all the wikipedia URLs that were used.
3. Check for citations (on the Candidate ) in the response from gemini.
4. Include the wikipedia license at the top.

Please adjust the licensing at the top, as we discussed.

Thank you for the review.

If you have used/derived something sourced from an MIT licensed repository

I'll consult with the OSS team as suggested.

Hi,
@markmcd after consulting with the OSS team, I have made necessary changes.

Also, @MarkDaoust, as you have access to that email thread, can you please review if the changes are inline with the team's advice?

Thank you.

I made a few fixes, and couldn't push direct to this brach, can you merge: mayureshagashe2105#1

Also: It's hard to find an example where this approach works.

[mayureshagashe2105]

@MarkDaoust I have updated the outputs as discussed. Thanks!

[mayureshagashe2105]

I think this is good to go!

Looks good - I fixed a few tiny nits. Nice work sneaking a PJO reference in there too 👀
