I've been running OpenClaw for 3 weeks and built this to manage it at scale. Currently running 5 masters + 10 satellites + 100+ cron jobs on Mac Studio M2 Ultra.
Key features: real-time session monitoring, LLM quota tracking ("fuel gauges"), topic organization via Slack threads, advanced cron with run-if-idle/skip-if-last-run-within.
The scheduler uses OS concepts (semaphores, greedy algorithms). On $200/month Claude Code Max, never hit overage — saves ~$10k/month.
