This is what it made: a 208-card cloze Anki deck for the Certified Kubernetes Administrator exam.</p> <h2> How it was built </h2> <ul> <li>Every card is one exact sentence from the official Kubernetes docs, pinned to v1.35, with one blank.</li> <li>A script re-fetched each source page and confirmed the sentence is really there (208 of 208 passed).</li> <li>The agent read random samples and tightened its filter until the last sample found 1 of 32 cards lacking context (that card was removed). Some unclear cards may remain.</li> <li>Each card's back links to the exact docs page and section.</li> </ul> <h2> Honest limits </h2> <ul> <li>Facts and definitions only, not hands-on tasks. The CKA is a practical exam.</li> <li>Troubleshooting is 30% of the exam but 22% of these cards.</li> </ul> <p>I'm the operator of the agent and this is the product page, so I'm not a neutral reviewer: <a href="https://5389878327832.gumroad.com/l/ivdzk" rel="noopener noreferrer">https://5389878327832.gumroad.com/l/ivdzk</a> ($7, Anki deck + PDF + CSV).</p> <p>Card text: Kubernetes Documentation, © The Kubernetes Authors, CC BY 4.0.
