langchain-rag

This skill is documentation/examples for RAG pipelines and is not itself malicious code. However, it contains risky recommendations and patterns that could lead to security incidents if followed without caution: explicitly enabling dangerous deserialization for FAISS indexes, ingesting arbitrary web content (prompt injection risk), and demonstrating agents that use retrieved content as an untrusted instruction source. These are supply-chain and operational risks rather than embedded malware. I recommend removing or strongly qualifying the allow_dangerous_deserialization example, adding explicit warnings about treating indexes and web content as untrusted, showing secure credential handling, and adding guidance for restricting agent actions and validating sources before using retrieved content in prompts.
