Context Engineering Quick Start

A short companion guide for pharma teams who want to start with context engineering — but don't know where to put their first document.
In 2026, the friction with AI has moved. It's no longer in what you say to the model. It's in what the model can see when it answers — the documents you load, the tools you connect, the memory you persist, the format you enforce.
This guide covers the basics in four pages. No jargon, no whitepaper bloat. The four layers of context, where to put them in the tool you already pay for (Microsoft Copilot, Gemini, ChatGPT, or Claude), what context documents actually look like with copy-paste templates, and a 30-minute plan to ship your first setup.
