What problem does it solve? Language learners forget vocabulary and grammar without timely review. This Skill runs a daily spaced-repetition session that resurfaces items just before they are forgotten, evaluates answers, and updates the SM-2 scheduling parameters so review timing adapts to actual performance. ## Core Features & Use Cases - SM-2 Review Queue: Pulls due items from the review queue, sorts by priority, and caps the session at the configured daily limit. - Adaptive Exercise Generation: Creates exercises matched to each item type — error patterns, vocabulary (recognition, production, or cloze), and grammar rules. - Automatic Rescheduling: Scores each answer, maps it to an SM-2 quality value, and lets the update script recompute intervals and rebuild future queues. - Use Case: A Dutch learner types /fluent-review each morning, reviews 20 due flashcards and grammar drills, and sees which items are mastered versus which return tomorrow. ## Quick Start Type /fluent-review to start today's spaced-repetition review session and work through each due item one at a time.
