It enables the iterative adjustment and testing of guardrail policies in alignment research through a controlled workflow. [langchain-decorators](https://github.com/ju-bezdek/langchain-decorators) reports 233 GitHub stars, 12 forks, and 6 open issues, last pushed Apr 18, 2026. [autoguardrails](https://github.com/SantanderAI) has 128 stars, 35 forks, and 2 open issues, last pushed Aug 1, 2026.
