alt Hacker NewsCodebuff is the easiest to use of all these, because you just chat, and it finds all the right files to edit. There's no clicking and you don't have to confirm edits.
It is also a true agent. It can run terminal commands to aid the request. For one request it could: 1. Write a unit test 2. Run the test 3. Edit code to fix the error 4. Run it again and see it pass
If you try out Codebuff, I think you'll see why it's unique!
Can codebuff handle larger files (6,000 loc) and find the right classes/functions in that code, or if it finds the file with the necessary info does it load the entire file in?
