I codify all my AI install/setup/running junk (https://codeberg.org/mutablecc/ai-agent-coding) with Makefiles. You can make DRY Makefiles real easy, reuse them, override settings, without the fancy stuff in the author's post. The more you build up a reusable Makefile, the easier everything gets. But at the same time: don't be afraid to write a one-off, three-line, do-almost-nothing Makefile. If it's so simple it seems stupid, it's probably just right.
