I'm thinking about upgrading to the Pro plan and want to know if Codex can actually help me add new features to a project that has over 100,000 lines of code. Has anyone tried it with a codebase of that size, and how well does it perform?

I’ve found Codex to be really impressive! While it might struggle to generate an entire project from scratch, it's fantastic at adding features or cleaning up well-structured codebases. Just the other day, I added a request while getting my kid to bed, and by the time I was done, Codex had a PR ready for me to merge. The only downside is it doesn't directly read GitHub issues, so I have to copy the issue text over for it to work effectively.
You should try the GitHub Copilot Coding Agent! Just assign it an issue, and it does the rest.
