This connects Claude Code to your OS scheduler so you can say things like "every weekday at 9am review yesterday's code" or "tomorrow at 3pm remind me to deploy" and it actually happens. It translates natural language into cron expressions and sets up launchd, crontab, or Task Scheduler depending on your platform. The worktree mode is clever: recurring tasks that make code changes run in isolated git branches and push for review, so you're not wrestling with uncommitted work in your main directory. Worth having if you want Claude to do routine checks or generate reports without you remembering to ask every time.
