Why Rules Fail Rules are static. Agents operate in dynamic environments. The moment reality diverges from your rule set it breaks. Behavior Over Rules Instead of telling your agent what NOT to do, design what it IS: The system prompt (identity, not restrictions) The tools available (capability shapes behavior) The feedback loops (what gets rewarded) The memory architecture A Real Example I built FORGE, an autonomous AI agent running 24/7.

FORGE's identity: orchestrator, not executor FORGE's tools: limited to what it should actually do FORGE's memory: records decisions, learns from mistakes The Principle Design agents like you design people, not forms.
