ToolGood.Words is a sensitive word filtering library and text sanitization component designed for high-performance detection and masking of prohibited terms. It provides tools for Chinese text normalization, pinyin transliteration, and the replacement of banned words with placeholders. The project is distinguished by its ability to uncover obfuscated language through a pinyin transliteration engine and phonetic-based detection. It identifies sensitive content hidden by phonetic substitutions, first-letter initials, or intentional misspellings by mapping Chinese characters to pinyin representa
LLM Guard is a security firewall and guardrail framework designed to scan and sanitize inputs and outputs for large language models. It functions as a proxy gateway and security layer to block prompt injections, toxicity, and sensitive data leakage while ensuring that model interactions remain compliant with organizational policies. The system distinguishes itself through a modular scanner pipeline that utilizes local model orchestration to eliminate external network dependencies. It supports real-time security filtering via streaming chunk analysis and implements a fail-fast execution model
