Reliably edit file without repeating the entire contents

[sestinj]

The current prompt for editing files requires the LLM to rewrite the entire range that it wants to edit. Ideally, it could specify only the diff, or at most a few lines surrounding the areas that it wants to edit.

To see the start of one attempt at this, look here. One idea on how to do this is by getting the LLM to output git merge conflict notation, like this:

<<<<<<< HEAD
<OLD_CODE>
=======
<NEW_CODE>
>>>>>>> updated

Other ideas:

• Fine-tune a model to generate a git diff
• Get the model to quote parts of the range it wants to edit
• Give the model tools like "insert here", "delete here", or "find and replace"

Hey @sestinj, I noticed this ticket is still open and doesn’t seem to be assigned to anyone yet. Would it be alright if I pick it up?

This would be great! I'd be happy to test or contribute. The link provided by @sestinj doesn't seem to work.
