create_flashcard_deck Read-only

Use this when the user asks to learn, study, memorize, review, practice, or create flashcards about any topic. Generate the complete deck in this call and open it in the interactive flashcard UI. Act immediately using the existing conversation and source material; infer language and backLanguage yourself. Never ask the user for language codes, tool arguments, or confirmation of an already requested deck. For a request for 50 cards, submit all 50 completed cards in one call. Keep the response brief and let the study UI show the deck. Examples include 'I want to learn about X', 'teach me X with flashcards', and 'Create an HSK3 vocabulary deck about restaurants'. Do not call a separate add-card tool. Do NOT use when the user asks for a direct explanation without study intent, asks to delete or modify an existing deck, or requests an in-conversation quiz without creating a deck.

cardsarray, required

The complete generated deck. Include exactly the number of cards the user requested, with every required language-learning field completed; never submit a partial array or placeholders.

titlestring, required

A concise, descriptive title for the generated deck.

languagestring

ISO 639-1 code for the language spoken on the front side (e.g. 'zh' Chinese, 'ja' Japanese, 'vi' Vietnamese). Used for the correct audio voice and saved-deck language. Always infer and set it from the user's target language, never from their current app preference.

backLanguagestring

Language of the translations on the back. Set from the user’s known language; never assume English. Always set for language-learning decks. Used for reverse-card audio.

create_website_deck

Use this when the user explicitly asks to save or share a deck on the website, or chooses Learn on website in the study widget. It sends the supplied deck to Fulin Labs and creates a persistent shareable deck link. Anyone with the link can read the deck. Do not call merely to preview or study a deck. Repeating the call may create another deck.

Argument	Type	Description
cards*	array	The cards the user explicitly chose to save on Fulin Labs.
title*	string	The title of the deck the user chose to save.
language	string	Optional language code for the deck's front side.
