Hi! Thanks for contributing to FOSSMate.

To get started with implementing pull_request.opened summary generation, I suggest we begin by outlining the data structures and APIs required to capture intent, changed areas, and review focus points. This will involve reviewing the GitHub PR API and identifying the relevant fields and endpoints.

Please go ahead and create a new issue or add a comment with your proposal for these data structures and APIs. Then, I'll review and provide feedback before we proceed with implementation.

Let me know if you have any questions or concerns!

Best regards,
