AWS Cloud Practitioner (CLF-C02) Skill

A full adaptive coaching system for the AWS Certified Cloud Practitioner exam (CLF-C02), packaged as a Claude Skill. Unlike a one-shot study plan, the skill runs real coaching sessions, tracks your weak spots across conversations, and tells you when you are genuinely ready to sit the exam.

What the skill does

• Two-phase coaching. Phase 1 builds domain coverage across all four CLF-C02 domains (Cloud Concepts 24%, Security & Compliance 30%, Cloud Tech & Services 34%, Billing/Pricing/Support 12%). Phase 2 is full-difficulty exam simulation.
• 10-question sessions with a mix of scenario PBQs, service-picker items, best-cost-effective picks, and shared-responsibility questions.
• Spaced repetition. Every wrong answer gets re-asked in a disguised form in later sessions until you get it right twice in a row.
• A mnemonic for every mistake. CloudTrail vs. CloudWatch, S3 storage classes, Well-Architected pillars, SNS vs. SQS — wrong answers always come with a memory trick you can actually remember under exam pressure.
• HTML progress tracker. After every session the skill generates a standalone HTML file with a mastery gauge, per-domain progress bars, topic chips, a session history strip, and an "EXAM READY" banner when thresholds are hit.
• Readiness signal. The skill declares you exam-ready when all domains reach 70% and you score 85%+ on 3 consecutive Phase 2 sessions — no guessing.

How it works

1. Intake — on first run the skill introduces itself, asks your level (beginner / intermediate / advanced), background, known weak areas, and target exam date.
2. Per-session loop — one question at a time, A/B/C/D. Correct answers get brief reinforcement. Wrong answers get a full breakdown + mnemonic, and the topic goes into your weak-topics list.
3. End-of-session artifacts — a summary table, a running scores table, the HTML progress tracker, and a phase-transition check.
4. Phase 2 flip — when all domains are ≥ 70% and your 3-session average is ≥ 75%, Phase 2 starts automatically. Harder questions, same structure, higher bar (85%+ × 3 in a row).
5. Continuity across sessions — the skill reads prior conversation state, so your weak spots, score history, and coaching persona carry forward without you having to restate them.

Quick-start prompt (no download)

Prefer a one-shot study plan without installing anything? Paste this into Claude:

Act as an AWS-certified instructor preparing me for the AWS Cloud Practitioner exam (CLF-C02). I have [X] weeks, [Y] hours per day, and my background is [describe it]. Produce:

1. A weekly schedule table allocating time proportionally to the four domain weights, front-loading Security & Compliance and Cloud Technology & Services.
2. A day-by-day breakdown with 3–5 concept bullets, the AWS services introduced, one free-tier-compatible hands-on task, and a recall question.
3. 5 multiple-choice questions per domain (20 total) in CLF-C02 style with a full answer key and rationale.
4. An exam-day cheat sheet: Well-Architected pillars, Shared Responsibility split, S3 storage class decision tree, pricing-model picker, Support plan ladder, and the top 15 most-tested services.
5. An end-of-week 20-question mock quiz for every week in the plan.

Never recommend deprecated services or patterns. Define Region/AZ/Edge Location the first time each appears. For each service, name the services it is most commonly confused with on the exam.

Tips:

• The downloadable skill is the better path if you have more than one study session planned — it's the difference between a static plan and a coach that remembers you.
• When you score below 70% on a domain, ask for a targeted re-study plan before moving on.
• Ask for real-world analogies when Region vs. AZ vs. Edge Location still feels fuzzy.
• Before exam day, run the cheat sheet alone without your notes — if you can produce it from memory, you are ready.
