RAG from Scratch with ChromaDB (No LangChain Required)
Frameworks like LangChain are great for moving fast, but they also hide a lot of what's actually happening under the hood. If you want to understand R…
We deployed a LangChain agent for a client and it silently failed for two weeks. Here's what we built to make sure it never happens again.
Six weeks ago, a LangChain agent we'd deployed for a B2B client started failing on roughly 30% of its sessions. No exceptions. No 500s. Nothing in the…
Your AI Agent Is Leaking Data Right Now — And Every Tool Call Looks Safe
How I built the first open-source tool to catch the attacks that no guardrail sees coming We talk a lot about AI safety. Prompt injections. Jailbreaks…
Делюсь опытом: ИИ-агент на Claude без LangChain и RAG — разбор архитектуры и развилок
Делюсь опытом: собрал прод-агента на Claude для небольшой студии дизайна интерьера. Чат отвечает на Haiku 4.5, генератор концепций — на Sonnet 4.6, фо…
Tell your AI agent if the ground is sinking: measured ground-motion with SibFly + LangChain
Most "is this property risky?" data your agent can reach is modeled — a prediction from soil maps and flood zones. There's a different, underused sign…
Why Prompt Engineering Isn't Enough for Production AI Agents
TL;DR: Autonomous Agents frequently get trapped in execution loops, burning through API tokens and compute. Prompt engineering can't guarantee executi…
Running a Whole RAG Agent Offline: LangGraph + Ollama + Embedded Qdrant (Zero API Keys)
Most RAG tutorials open with "set your OPENAI_API_KEY ." This one doesn't need it. In Part 1 I claimed the LLM and embeddings are behind a swappable b…
Design Trade-offs: Why Hermes (and Many Popular Agents) Don't Use LangChain / LangGraph
Note: The Hermes repo contains no explicit statement saying "we don't use LangChain because…". This article works on two levels: the industry-wide com…
