For those who don't like to be "surprised" by tech jargons, this skill is for you. I created a skill for explaining and practicing tech concepts tailored for CCAF. It teaches the ~38 foundational computer-science concepts a non-technical learner needs to read CCA-F exam material fluently — JSON, JSON Schema, glob patterns, environment variables, caching, Docker, tokens, and more. Each concept is anchored to the specific exam topic where it appears, and taught only as far as the exam needs it. It runs a 3-step loop per concept: 1. Explain — plain-language definition + real-world analogy + one sentence on why it appears in the CCA-F exam. 2. Feynman — one open-recall question. 3. Quiz — one MCQ wrapped in a CCA-F-style scenario (never an abstract textbook example). I have tested myself and quite like it. Hope it's helpful for you: ccaf-exam-tech-foundation. Feedbacks are very welcome!
