It enables the iterative adjustment and testing of guardrail policies in alignment research through a controlled workflow; pick circle-guard-bench if circle-guard-bench is a Python-based AI benchmark tool for evaluating large language model guard systems under various protection scenarios. [autoguardrails](https://github.com/SantanderAI) reports 130 GitHub stars, 36 forks, and 2 open issues, last pushed Sep 1, 2026. [circle-guard-bench](https://whitecircle.ai) has 75 stars, 5 forks, and 1 open issues, last pushed Mar 7, 2026.
