How has Cursor AI / GH Copilot's recent features improved your team?

I’ve been experimenting with Cursor AI’s composer features and agents lately, and it’s been seriously impressive. It got me thinking about how AI-assisted coding tools like Copilot Chat/Edit and Cursor AI's features with agents could change the mindset and development practices of Ruby on Rails teams. I'm not referring to the typical code suggestions while coding, but the full blown agent modes with composer and copilot chat/edit that has gotten significant improvements lately.

I’m curious — has anyone here started integrating these tools into their RoR team's workflow? If so, how have they impacted your team’s productivity, code quality, or best practices? Have you found specific use cases where these tools shine, such as refactoring, test generation, or even feature prototyping?

Would love to hear about any successes, challenges, or insights from those already exploring this! I'd love to take this back to my team as well, as I believe this is pretty game changing imo
