This is actually possible, I made a proof of concept agent that does exactly this. The agent has access to several commands that get executed on demand - ListFiles, ReadFile and WriteFile. You give it a prompt - for example "add a heading to the homepage and make it yellow" and it will use ListFiles to locate the correct file, then use ReadFile to read it and then finally use WriteFile to write the new contents of that file. It was just a PoC so it wasn't bulletproof and I only ever made it work on a small Next.js codebase (with every file being intentionally small so it fits the context window) but it did work correctly.
