Return the flashcards of a single Memora deck and display them as an interactive flip-card review (due cards first). Available decks: "Geography::World Capitals", "Geography::Rivers", "Science::Solar System", "Language::Spanish Basics". Deck names use "::" to form a category tree; use the study tool to review a whole category. Decks are read live from data/decks.json.

Study every card under a category node of the deck tree. Deck names use "::" to nest (e.g. "LLM::Attention"); studying a node reviews all decks at or under that path, merged and shuffled into one session. Omit path to study all decks. Each card stays attributed to its source deck.

Create (or extend) a flashcard deck from cards you generate based on the user's request or the current conversation, then display it for review. Use "::" in deck_name to nest under a category (e.g. "LLM::Attention"). The deck persists to data/decks.json.

Follow Memora's card-quality rules (based on Wozniak's '20 Rules of Formulating Knowledge'). The front is the prompt/question, the back is the answer:

1. Minimum information (atomic): each card tests exactly one fact or concept. Split complex material into several simple cards; never ask for lists or paragraph answers.

2. Concise answers: the back is ideally 1-5 words (a name, date, term, or single concept), never a sentence or paragraph.

3. Active recall: make the front a specific question (not 'Explain X'), or a cloze deletion: write the blank as "[...]" in the front and the hidden term as the back (e.g. front "The Transformer was introduced in [...].", back "2017").

4. Unambiguous: each front must point to exactly one correct answer.

Set reverse=true to also add the back->front version of each non-cloze card (useful for vocabulary or term/definition pairs that should be drilled both ways).

Create (or extend) a multiple-choice quiz deck from questions you generate based on the user's request or the conversation, then display it for review. Use "::" in deck_name to nest under a category. Persists to data/decks.json and is reviewed like flashcards with spaced repetition.

Each question: a clear, specific prompt; 3 to 4 concise options with exactly ONE correct answer and plausible (not obviously wrong) distractors. The answer must match one of the options exactly.

Record a spaced-repetition review result for a single card and update its FSRS schedule in data/decks.json. Called by the flip-card UI; not for direct model use.

Edit a card's front and/or back in a deck, identified by its current front text, then re-render the deck. Keep edits within Memora's card-quality rules (atomic, concise 1-5 word answers, unambiguous).

Rename a deck, preserving its cards and schedules. Use "::" in the new name to move it under a category. Fails if a deck with the new name already exists.

Delete a single card from a deck, identified by its front text. Refuses to delete a deck's last card (delete the deck instead).

Delete a deck and all its cards. Refuses to delete the only remaining deck.

Summarize what is due to review right now across all decks: per-deck and total due/new counts. Pull-based (call it to see the summary); it does not appear on its own.
