This is great, and nicely written up in the context of agentic repos etc, but presumably no-one reads the official docs, right: https://git-scm.com/docs/gitignore where the multiple ways of ignoring files are clearly stated?

Until Claude suggested .git/info/exclude, it never crossed my mind to question how ignoring worked. A search would have answered it in seconds, but you have to think to ask first. I didn't, and I suspect most people don't either. Especially with git, which nearly everyone learns by doing; very few of us ever sit down and learn it properly. That's why I wrote it up: so a few more people can learn this the way we learn everything else in git, by accident.

Now that you mention it, I should add a link to those docs in the article. Thanks!

There is a tweet doing numbers on Twitter right now which is effectively:

"Do the reading b/c you would be amazed how many people don't do the reading"

For a lot of tools, people usually read the docs once, and obscure stuff is quickly forgotten.

I have never seen these two files in any git repository I've cloned so far.
