## Tools (3)

- `create_flashcard_deck`: 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.
- `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.
- `speak_text`: Use this when the flashcard widget requests speech audio for the current card.
