I'd like to automatically generate a file and add it to a commit if it has changed. Is it possible, if so, what hooks should I use?

Context: I'm programming a CSS library. It has several CSS files, and at the end I want to produce a compacted and minimized version. Right now my workflow is:

Modify the css files x.css and y.css
git add x.css y.css
Execute minimize.sh which parses all the css files on my lib, minimizes them and produces a min.css file
git add min.css
git commit -m 'modified x and y doing foo and bar'

I would like to have steps 3 and 4 done automatically via a git hook. Is that possible?

I've never used git hooks before. After reading the man page, I think I need to use the @pre-commit@ hook. But can I invoke git add min.css, or will I break the internet?
