For developers learning AI application engineering, this article maps the complete RAG pipeline from ingestion, chunking, retrieval, reranking, and generation to evaluation and operations, and presents an evolution path from a minimal viable solution to production.
This article systematically explains the core concepts and four-stage workflow of Spec-Driven Development, as well as its fundamental difference from vibe coding. Drawing on today’s tools and maturity levels, it explains why writing a specification before implementation substantially reduces ambiguity and rework in the age of AI coding agents.
Drawing on benchmarks and industry practice from multiple organizations, this guide presents default RAG chunking settings, parameter-tuning methods, and strategies for different document types.
LangChain’s breakdown of the agent harness connects context engineering, memory, MCP, and the agent loop into one coherent map.
A long-form Prompt Engineering guide for AI application engineers, covering foundational principles, context design, task chains, injection defenses, agent prompt design, and evaluation-driven development.
Starting from Anthropic’s Contextual Retrieval article and Appendix II, these notes summarize the core method, experimental findings, and RAG architecture principles suitable for production.
A curated list of ten high-value articles on Contextual Retrieval, Context Engineering, and RAG evaluation, spanning Anthropic’s original publications, open-source implementation guides, and a review of 2025 trends.
A practical breakdown for AI engineers of what the M5’s changes over the M4—from CPU, cache, and memory bandwidth to Neural Accelerators—mean for local LLM and diffusion inference.
Prompt engineering? It may not be as simple as you think.
Understand LLM prompt injection and several fundamental defensive measures.
