Context Guardian: A Practical Solution for Local Model Context Management

Context Guardian is an open-source plugin maintained by LuminariSoftwares, designed to resolve session interruptions caused by context window overflow in local models. It offers two modes—an OpenAI-compatible proxy and a DeepSeek Harness native engine—with support for deterministic compression. Its key features include fail-open behavior, disk persistence of raw data, and retrieval of archived context. Users can enable this functionality by configuring the proxy or integrating DSH, ensuring stable sessions and preserving historical details while keeping context length within limits.
