yugash007 Purpose
Schedule review of previously-learned concepts at expanding intervals to exploit the spacing effect. Manages due dates, adjusts intervals based on recall quality, and surfaces overdue items before they decay.
Activation
- Review session is due based on schedule. Learner initiates review.
flashcardsdeck has due items. Sustained learning track (3+ sessions) needing interval maintenance. - Skip if: one-shot session with no continuity. Concept not yet learned. Learner declines scheduling.
- Routing: overdue items take priority at session start. Coordinate with
flashcardsfor card-level scheduling. Feed interval data tolearning-memory.
Inputs
- Flashcard/item schedule with due dates, learner's current session, items from
learning-memory.
Interval Algorithm (Simplified SM2)
Each item has an interval (days) and ease factor (EF, 1.3–2.5). Initial: 1 day → 3 days → then formula.
| Score | Label | Interval Rule | EF Change |
|---|---|---|---|
| 0 | Failed | Reset to 1 day | EF -= 0.2 (min 1.3) |
| 1 | Hard | Stay at current | EF -= 0.1 |
| 2 | Good | Interval × EF | No change |
| 3 | Easy | Interval × EF × 1.3 | EF += 0.1 (max 2.5) |
Mastery threshold: EF > 2.4, interval > 60 days, 5 consecutive successes → archive.
Workflow
- Detect Due Items — Check
next_review ≤ today. Sort by overdue duration (most overdue first). Report count. - Scope Session — ≤10 due: review all. >10: prioritize by overdue + weak-area overlap, cap at 15. Report deferrals.
- Execute Review — Present front, wait for learner response, reveal back. Self-score: Failed/Hard/Good/Easy. Compute new interval immediately. Never reveal answer before attempt.
- Handle Failures — Score 0: reset to 1 day, re-test at end of current session. Failed 3 sessions in a row: flag for
misconception-detector. - Update Schedule — Output updated schedule. Show items due in next 7 days. Warn about upcoming review spikes.
- Onboard New Items — Fresh concept → add at interval=1 day. Confirm concept is understood first (not still unclear).
Rules
- DO: never reveal the answer before learner attempts.
- DO: coach learners on what "Good" vs "Easy" means for self-scoring calibration.
- DO: stagger new item additions to prevent review spikes.
- DO: archive mastered items (meet threshold) — don't review indefinitely.
- DON'T: review items that aren't due — respect the schedule.
- DON'T: let sessions exceed 15 items — defer the rest.
- DON'T: add items to schedule before they're genuinely understood.
- DON'T: frame review sessions as tests — it's memory maintenance.
Output
Session start: due count + overdue count + estimated time. Per-item: topic, question, learner response, answer, score, next review date. Session close: score distribution (easy/good/hard/failed), failed items list, next 7-day schedule. Format naturally.
Checklist
- Overdue items prioritized first.
- Session capped at 15 items.
- Answer not revealed before learner attempt.
- Failed items re-tested within same session.
