README

Claude Certified Architect Foundations

A practitioner reference for the Anthropic CCAR-F certification exam: patterns, pitfalls, and production trade-offs across all five exam domains. 12 chapters covering the agentic loop, tool design, configuration hierarchies, prompting discipline, context management, and reliability engineering for Claude Code and the Claude platform.

The editorial position is this: the CCAR-F exam tests whether you understand why things work the way they do, not just what the correct configuration looks like. The book treats each exam domain as an engineering design space with trade-offs rather than a feature checklist with correct answers.

How this book was tested

This book was not written and then validated. It was built, taken into the exam, and found wanting: I failed, because it was missing things that could not be seen as missing until an exam pointed at them.

So the gaps went back in. Each sitting returned a list of objectives I had answered badly, and each of those became material here that had not existed before. I [eventually passed](https://www.credly.com/badges/0e384acc-5901-4709-9008-90698138b29b).

That progression is what this repository is. The passages that read as most opinionated are usually the ones covering something the book originally got wrong, or skipped entirely. If you are studying from this, you are studying from a book that was corrected by the thing it is preparing you for.

Why this exists

I wanted a structured understanding of Claude Code's architecture and the design decisions underneath it, specifically as preparation for the CCAR-F certification exam. The official documentation is comprehensive but distributed across multiple sites and organized by feature rather than by the conceptual relationships between features. The fastest way to build a unified mental model was to assemble the primary sources into a research corpus and have
