What problem does it solve? Language learners forget vocabulary and grammar unless they review items at the right moment. This Skill runs the daily spaced-repetition review queue, pulling items scheduled by the SM-2 algorithm, testing the learner on each one, and rescheduling items based on performance so nothing slips through the forgetting curve. ## Core Features & Use Cases - Due-Item Queue Loading: Reads spaced-repetition.review_queue.today, sorts by priority (critical to low), and caps the session at the daily item limit. - Adaptive Exercise Generation: Creates targeted exercises per item type — error patterns, vocabulary (recognition, production, cloze), and grammar rules — presented one at a time. - SM-2 State Updates: Scores each answer, maps it to a quality value, and passes review_results[] to the database updater which recalculates easiness factors, intervals, and repetitions. - Use Case: A Dutch learner types /fluent-review each morning. The Skill presents 12 due items, evaluates each answer with feedback, and reschedules mastered items weeks out while missed items 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.
