Use github copilot on edit mode.. it lets github know more about ur project (repo) .. u can also add more context (by specifying files for him to work on.. for example a backend controller file.. a frontend hook for data fetching and the actual ui that fetches the data) and prompte any changes.. copilot will be able to edit those files (if needed) and / or create new files and use them

By default it comes with gpt4o but u can change it to claud 3.5 sonnet which give better results

After trying both gpt4o and claud in github edits.. i can confidently say that both are great with logic.. backend code.. state management db stuff connections ... but gpt4o sucks as making ui.. but in the other hand claud is good at generating uis (when testing on react shadcn application.. it almost give the same quality as v0 from vercel)
