    What Is OAuth? And Why AI Agents Depend on It

    Why OAuth Is Critical for Reliable AI Agents A lot of AI agent failures don’t actually come from the model. They often just stem from broken authentication. The setup might work fine during testing, but once the first access token expires, the background refresh flow can fail, leaving the agent unable to complete tasks. Humans can simply log in again…

    How to Build a RAG System with pgvector and LangChain: The Production Architecture

    How to Build a RAG System with pgvector and LangChain: The Production Architecture Most production AI failures are not model failures. They are retrieval failures. If you want to understand why your RAG system is hallucinating, stop looking at your prompt. A perfect prompt with the wrong data yields a confident hallucination. An average prompt with the correct data yields…
