A property manager was spending hours every week doing the same thing: scanning emails for deposit payments, matching them to tenants in a spreadsheet, updating balances, and chasing people who hadn't paid. The setup: • 1 admin agent (Opus) — touches config, never does actual tasks • 6 worker agents (cheaper models) — handle daily work • A rental manager agent scans email, pulls deposit data, registers it to the right tenant/property, and reports every morning at 8am: who paid, who hasn't The result: • 70% reduction in manual spreadsheet work • Weekly review instead of daily grind • Admin agent creates "last good config" snapshots before any change, so the system can always roll back if something breaks The detail worth stealing: workers are blocked from touching config files. Only the admin can. That's proper security architecture, not just a multi-agent flex. The person running it says it now takes minutes of review instead of hours of manual work. Not flashy. But it runs every day, reliably, while they do something else. What boring, repetitive task in YOUR business hasn't been automated yet? Reply below, let's find your equivalent.
