Verification Loop
In AI agent architecture, a feedback mechanism in which an independent evaluator inspects and validates generated results. It separates generation from verification to ensure controllable quality.
Timeline (last 90 days)
The verification loop requires an independent evaluator to check the results produced by the agent; the evaluator cannot be the evaluatee itself, otherwise it loses its error-correction purpose.
The verification loop differs from the self-reflection pattern: self-reflection has the same model evaluate itself, which easily perpetuates its own blind spots; the verification loop emphasizes separation between the generator and the evaluator in role, context, and even model.
In Lauren Tan's metaphor, Skills correspond to recipes and operating procedures, CLI and deterministic scripts correspond to kitchen-specific tools, Lint rules and the type system correspond to physical constraints, and the verification loop corresponds to the tasting and quality-control steps.
What distinguishes the verification loop from simply "asking the model again whether it is right" is that the basis for checking is the source text rather than the model's own judgment, so it can catch transcriptions that the model is confident about but that are wrong.
Without verification, an agent cannot see the results of its own work and therefore cannot truly iterate; the verification step is the core of what makes the agent loop a loop.
