Current Retrieval-Augmented Generation (RAG) systems face a fundamental completeness-precision dilemma: vector-based approaches optimize for precise needle-in-haystack retrieval but sacrifice comprehensive context through isolated chunk retrieval, while knowledge graph systems aim for completeness but suffer from query specificity challenges and complex traversal overhead. We present **Topological RAG**, a graph-based architecture that reconstructs semantic "small worlds" through weighted multi-hop traversal, prioritizing comprehensive corpus coverage over retrieval speed.

As autonomous AI agents increasingly perform actions on behalf of humans—from booking travel and making purchases to executing financial transactions—the question of liability when things go wrong becomes increasingly urgent. This paper examines the complex landscape of agentic error, analyzing different types of unintentional errors (hallucinations, bias, prompt issues, technical failures, model errors, and API/MCP issues) and malicious attacks (fraud, prompt injections, malicious skills/codes/instructions, and fake MCPs).
