Cca F Prep Kit — Development skill for Claude Code

The CCA-F Prep Kit

**Walk into the Claude Certified Architect Foundations exam in thirty days with a mock score you can trust and eight build projects you can defend.**

Companion repository to *Claude Certified Architect Foundations Playbook*, from [youcanbuildthings.com](https://youcanbuildthings.com).

Two things live here. A **study half** (a thirty-day plan, five one-page cheat sheets, sixty practice questions and a scorer) that works the second you clone it, with no account, no API key and no internet. And a **code half**: eight small Python projects from Chapters 4 through 10, which do call Claude and do need your own key. "MCP" is a plug standard for giving an AI tool access; "structured output" means making the model return JSON that always matches a shape you chose; "silent failure" is an answer that looks right and isn't. You build one small thing for each. Start with the study half below; the code half is in `chapters/`.

Start here

**"I just got the book and I don't know where I stand."**

git clone https://github.com/regardo911/cca-f-prep-kit && cd cca-f-prep-kit
python3 study/score_mock.py --diagnostic

Five questions, one per domain. It asks, you answer, and it tells you which of the five domains is your weakest and which chapter folder fixes it. Thirty seconds, and it is the first thing Chapter 1 asks you to do.

**"I've worked through the chapters and want to know if I'm ready."**

git clone https://github.com/regardo911/cca-f-prep-kit && cd cca-f-prep-kit
python3 study/score_mock.py --template > my-answers.txt
# sit study/mock-exam.md in one two-hour block, fill in my-answers.txt
python3 study/score_mock.py my-answers.txt

Sixty questions, weighted 16/11/12/12/9 to match the real blueprint. You get a score per domain and the book's own go/no-go rule: 80% or better, book the date.

**"I just want the eight build projects."**
