Stop Giving Your AI Agent a Search Box and Start Giving It Typed Tools, Hard Bounds, and a Gate It Cannot Talk Past

Fixed RAG pipelines are limited because they retrieve all information in a single pass before reasoning, which is insufficient for complex, multi-step questions. A more advanced approach gives an AI agent a set of typed tools and hard boundaries to navigate a knowledge graph, rather than a simple search box. This allows the agent to interleave reasoning with retrieval, discovering what to retrieve next based on what it has already found. The proposed system also includes a "contradiction gate" to ensure the agent's autonomy does not bypass governance and safety protocols. This design aims to create a more capable and auditable system by controlling the agent's actions through a specific vocabulary of tools.
