Agents are not Apps: Stop building interfaces, Start building coworkers
summary
An agent named Ella runs for five months over Telegram, handles RSVPs, builds an RSVP website, creates a budget tracker, and books four vendors for a wedding of 100 guests, running on about a $5 VPS and a ChatGPT subscription. Architectural advice: use event triggers (webhooks/cron), keep deterministic checks before handing off to agents for judgment, store memory in a file-system first, require verification (programmatic tests or human approval), and grant autonomy gradually.
