Alright, let's cut through the usual "it magically works with git!" marketing fluff. I've seen enough hand-wavy claims about "deep integration" to be deeply suspicious.
So, Aider says it can read your git repo and make commits. Great. But I'm not buying the magic. My working theory is it's just a glorified file watcher with some `git diff` parsing, wrapped in a shiny API. Prove me wrong.
From poking around and reading between the lines of their docs, here's my best guess at the actual mechanics:
* **The "Context" is just a snapshot.** When you start a chat, Aider presumably runs a `git status` and `git diff` (maybe `git diff --cached` too) to get the current state. It slurps relevant files into the LLM context. No magic, just standard ops.
* **Changes are applied as patches.** When you ask for an edit, the LLM outputs a diff/patch format (likely unified diff). Aider then applies this patch to the working directory files. This is basic `patch` command logic, not some proprietary git wizardry.
* **Commits are automated shell commands.** After changes are made, Aider can run `git add` and `git commit` with a generated message. This is trivial automation. The "intelligence" is just the LLM writing a commit message based on the diff.
My real concerns are around the **illusions** this creates:
* Does it *truly* understand the repository history, or just the current state? I'm betting on the latter.
* How does it handle merge conflicts if you're editing a file that changed on another branch? My guess is poorly, or not at all.
* The risk of "hallucinated" code being seamlessly committed because the patch applied cleanly is non-zero.
I'd love to hear from anyone who has actually dug into the source or had it break in a way that reveals the scaffolding. Until then, I'm filing this under "clever wrapper, not revolutionary tech."

If it's free, you're the product. If it's expensive, you're still the product.
You're actually pretty close on the basics! It's less magic and more clever plumbing. The core of it really is that diff/patch cycle with the LLM.
But you're missing the tricky bit: how it handles partial context and only sends the LLM what's needed. If you have a massive monorepo, it's not just slurping everything. It uses git to figure out which files are related to your chat request, which is where the "integration" feels deeper than a simple file watcher. It's mapping your natural language request to specific paths in the tree.
The commit automation is straightforward, you're right. The real value is in making that edit-apply-commit loop feel seamless, and knowing *what* to stage. It sometimes gets confused on hunks, though. I've had it try to commit a debug log it added by mistake 😅
cost first, then scale
