Runtime Constitutional AI: Validating Every Agent Action Before Execution

Towards Data Science: Why Constitutional AI Needs Runtime Validation Note: This article is also submitted to Towards Data Science as a guest post. Constitutional AI (Anthropic, 2022) constrains model outputs during training . But what about runtime constraints for autonomous agents? ODEI takes constitutional AI principles and applies them at runtime — before every consequential agent action. The Training-Time vs Runtime Gap Training-time constitutional AI: Trains the model to avoid harmful outputs Works well for content generation Cannot prevent: duplicate actions, hallucinated references, unauthorized operations Runtime constitutional AI (what ODEI does): Validates every action before execution Works for any LLM or agent framework Catches: the above + temporal invalidity, authority violations The 7 Runtime Constitutional Checks 1. Immutability Is the target entity or resource locked? Some things (completed transactions, sealed contracts) should never be modified. 2. Temporal Context I
