Six Card Kinds, One QA Gate: What a Good Flashcard Skill Actually Encodes

Ask most flashcard generators — AI-powered or otherwise — to turn a page of notes into study cards, and you'll get a uniform stream of front-and-back pairs. Every fact gets the same treatment regardless of its actual shape. That's the default, and it's also quietly the wrong default, which is what makes aitutors.me's flashcards skill worth looking at closely: it's built around the idea that different facts have different shapes, and forcing them all into one card format is a design failure, not a simplification.

Why one format for everything is actually a cost

Consider a name-and-definition pair versus a sentence with three blanks to fill. Force both into a generic "front/back" card and you lose real information. The name-definition pair genuinely benefits from being tested in both directions — recognizing the term from its definition is a different skill from recalling the term itself, and testing only one direction leaves half the actual learning goal unmeasured. The three-blank sentence, treated as one card, either tests all three blanks at once (which fails as soon as one is wrong, hiding whether the other two were actually known) or gets manually split by whoever's making the cards, which most people don't bother doing consistently.

The skill's answer is to maintain six distinct card kinds — basic, basic-reversed, type-in, cloze, cloze-multi, and image-occlusion — and route each fact to the kind that actually matches its shape. A reversible pair gets tested both directions automatically. A multi-blank sentence fans out into one card per blank without anyone splitting it by hand. The taxonomy isn't decoration; it's the mechanism that keeps a generated deck from being worse than one a careful human would make.

The rule that catches the failure nobody notices

The other design choice worth dwelling on: a hint can never contain a word of four or more characters that also appears in the answer. This is a strange, specific rule until you notice what it's actually preventing — the extremely common pattern of writing a hint that half-answers the question by echoing the answer's own vocabulary. "Sounds like a door hinge" as a hint for the word hinge isn't a hint at all; it's the answer with a fig leaf. A generic AI asked to "write a helpful hint" will produce exactly this failure constantly, because it's a locally reasonable-sounding sentence that only reveals its uselessness once you check it against the actual answer word by word.

This is the kind of rule that only gets written by someone who's watched a lot of bad flashcards get made — it's not a rule you'd derive from first principles about learning theory, it's a rule you'd derive from pattern-matching real failures and then encoding the fix as something checkable, rather than something you hope a generator remembers to avoid.

The one-fact-per-card discipline

The third load-bearing rule — if a front needs "and" to be a complete answer, it's two cards, not one — is the most familiar-sounding of the three but the easiest to violate under time pressure. It's tempting, when generating cards quickly, to bundle related facts for efficiency. The skill's position is that this efficiency is false: a card testing two things at once produces ambiguous signal on review — getting it "half right" doesn't tell you which half you actually knew, which defeats the entire point of spaced repetition as a diagnostic tool, not just a repetition tool.

What this says about skill design generally

Step back from flashcards specifically and there's a broader lesson here about what separates a genuinely useful AI skill from a thin wrapper around a capable model. The model can already generate flashcards without any skill at all — what the skill adds is the accumulated, checkable knowledge of exactly how that generation goes wrong, encoded as rules an agent has to satisfy rather than aspirations it might remember. A skill worth using is rarely "do the thing" — it's "do the thing while avoiding the specific, named ways doing it badly looks fine at first glance."
