Effective Engineering Prompting 2026

A practical book: how to design instructions, context, and control for RAG, support, call centers, assistants, orchestrators, and agents. No jailbreaks and no spellbooks that outlived the models they were written for.
Read this book as an engineering manual, not a collection of clever phrases. The core idea is simple: in 2026 a prompt is part of an executable contract, not pretty text, and you should treat it like code - with boundaries, checks, and versions.
We'll walk the whole path: from simple tasks like classification and extraction to RAG, support, voice assistants, orchestrators, and agents. Every chapter is not incantations but a breakdown of what makes a model behave the way it does and how to be accountable for it.
The book distills the primary sources of OpenAI, Anthropic, and Google into a single engineering picture. Links to the specific materials are collected in the last chapter.
