A developer explored two patterns for enhancing the reliability of LLM agents interacting with external systems: Contract-First and Assertion-First. The Contract-First approach defines a strict output schema that LLM responses must adhere to, offering clear interfaces and fast failure but lacking flexibility. Conversely, the Assertion-First method allows the LLM more freedom, asserting on the results afterward, which is more flexible but harder to debug. The author recommends a hybrid approach for production agents, using Contract-First with a fallback assertion layer for optimal reliability. AI
