If you want determinism, you ask Claude Code to write you a computer program to the desired specs, and then run that program over and over again, instead of renting the software from a SaaS vendor. I've done that a bunch - I'll show Claude the inputs, I'll tell it what output format I want, tell it the tech stack, and then have it write the program. Then I'll ask for a systemd service or crontab entry to run it repeatedly.

For a lot of tasks, classical deterministic computer programming is better than an LLM. It's just that LLMs are very good at classical deterministic computer programming now.
