Antfarm cons

Antfarm gotchas
- This is an add-on, not a full standalone assistant, so you will usually pair it with another agent.
- You should expect ongoing hosting, uptime, and secret-management work if you deploy it for real users.
- Recurring subscription or model spend can matter more than the headline feature list.
