The fundamental difference between a state machine circuit breaker and prompt guardrails is that the state machine circuit breaker does not rely on the model's interpretation of natural language instructions, but is enforced at runtime by external code, making it deterministic and non-bypassable.

UnverifiedIn harness engineering, code validation at key decision points should serve as a gatekeeper that cannot be bypassed, while natural-language rules are responsible for understanding and communication, the two being complementary rather than an either-or choice.74% similarUnverifiedPrompt injection is difficult to defend against with traditional firewalls because it does not rely on code vulnerabilities, but exploits the model's tendency to obey natural-language instructions, and its attack surface completely overlaps with normal functional input.72% similarUnverifiedCompared to chain-call frameworks such as LangChain, declarative state machines offer verifiability, with task dependencies, failure retry logic, and concurrency boundaries determinable at compile time71% similarUnverifiedSystem prompt-based solutions are essentially natural language conventions and can easily be bypassed by jailbreak attacks, prompt injection, or unintended model behavior.71% similarUnverifiedSystem prompts are not hard code constraints, but more like a piece of natural language text with a relatively high priority.70% similar
