Agent Systems — Field Notes
Field notes from building with teams of AI agents.
- Two of three must agree: adversarial verification for agent output An agent once reported a broken edit as verified. My adversarial verification: skeptics that try to refute, and two of three verifiers to confirm.
- Guardrails as skills: no backtest gets reported until the checks pass Guardrails as skills: my Claude Code skill won't let agents report a backtest until data validation, bias guards and multiple-testing corrections pass.
