Loop Engineering for RAG Generation: iterate top-k one at a time

3+ hour, 42+ min ago   (927+ words) Enterprise Document Intelligence [Vol.1 #8bis] – Two regimes for sending retrieved candidates to the generation brick, the sufficiency signal that picks between them, and the per-question type dispatch that makes it cheap Naive RAG ships batch by default. Retrieval returns top-5, the…...

Build an LLM Agent That Can Write and Run Code

6+ hour, 15+ min ago   (1364+ words) A hands-on walkthrough of code execution with the OpenAI Agents SDK and Docker Code execution is probably one of the most useful capabilities we can give to an LLM agent. Once the agent can write and execute code, many tasks…...

Detecting Vulnerabilities in Agent Skills with SkillSpector: From Green Checkmark to Real Security Judgment

8+ hour, 12+ min ago   (1806+ words) Static analysis nailed the malicious skill and over-flagged the useful one. The gap between those results is where human judgement actually earns its keep. An agent skill is a simple package of instructions for an AI agent. In practice, it…...

Prompt Engineering Isn’t Enough: How Four Bricks of Context Engineering Stop RAG Hallucinations

1+ day, 3+ hour ago   (743+ words) Enterprise Document Intelligence [Vol.1 #9bis] – Your RAG isn’t hallucinating, it’s answering the wrong context faithfully. On real NIST and World Bank documents, watch each of the four bricks break, and the contract that closes it In the previous two articles (Part…...
