What problem does it solve? Language learners struggle to retain vocabulary long-term because they study words in isolation, cram without spacing, and lack structured review schedules. This Skill implements evidence-based vocabulary acquisition using the SM-2 spaced repetition algorithm, multi-modal encoding, and production-focused exercises. ## Core Features & Use Cases - Spaced Repetition Reviews: Tracks each word's interval, ease factor, and review history in a JSON database, scheduling reviews at optimal intervals based on the SM-2 algorithm and Cepeda et al. (2006) research. - Multi-Modal Vocabulary Introduction: Presents each new word with IPA pronunciation, mnemonics, collocations, word families, frequency rank, and contextual example sentences. - Exercise Generation: Creates seven exercise types including fill-in-the-blank, multiple choice, matching, sentence production, cloze tests, odd-word-out, and dictation. - Use Case: A Spanish learner asks to review vocabulary; the agent queries vocab.json for due words, presents randomized recall questions, updates SRS parameters based on self-assessed quality, and saves progress immediately. ## Quick Start Ask the agent to start a vocabulary review session for your target language, and it will pull all words due today from your personal vocabulary database.
