Letting Claude Code's Routines continuously tune my CLI's performance

I had been thinking about what to actually do with Claude Code's Routines feature for a while. It runs prompts in the cloud on a schedule, which sounds useful, but what's actually worth firing every couple of hours? What I landed on is performance tuning . "Did it get faster?" is a question you can answer with numbers, so as long as you have a benchmark in place, the rest can be handed off to an AI. If you have tests, regressions get caught for you. The work happens on a branch, so nothing leaks
