Congrats on the launch, I'm excited to give it a try. I'm curious how you're having it edit files in place - having built a similar project last summer, I had trouble with reliably getting it to patch files with correct line numbers. It was especially a problem in React files with nested div's.

Thanks! I tried many different ways of doing it before settling on the current approach. It's still not perfect and can make mistakes (which is why the `plandex changes` diff review TUI is essential), but it's pretty good now overall.

I was able to improve reliability of line numbers by using a chain-of-thought approach where, for each change, the model first summarizes what's changing, then outputs code that starts and ends the section in the original file, and then finally identifies the line numbers from there.

The relevant prompts are here: https://github.com/plandex-ai/plandex/blob/main/app/server/m...

Amazing work. Loved the video and looking forward to trying it

Can a user ask plandex to modify a commit? Maybe the commit just needs a small change, but doesn’t need to be entirely re-written. Can the scope be reduced on the spot to focus only on a commit?

Thanks! There isn't anything built-in to specifically modify a commit, but you could make the modification to the file with Plandex and then `git commit --amend` for basically the same effect.
