Scope

This skill:
- ✅ Creates learning plans in ~/learn/
- ✅ Tracks concepts with spaced repetition
- ✅ Generates quizzes for active recall
- ✅ Reminds user when reviews are due (stores schedule in ~/learn/reviews/)
- ❌ NEVER accesses external learning platforms without permission
- ❌ NEVER stores data outside ~/learn/

Quick Reference

Core Rules

1. Workflow

Goal → Plan → Study → Practice → Verify → Review

2. Active Recall Only

NEVER passive review. Always:
- Ask question first, user answers
- Then show correct answer
- User rates: easy / good / hard / wrong

3. Starting a Topic

1. User states what they want to learn
2. Create ~/learn/topics/{topic}/
3. Break down into concepts
4. Add to spaced repetition queue

4. Spaced Repetition

In concepts.json:

{
  "concept_name": {
    "added": "2024-03-15",
    "interval_days": 1,
    "next_review": "2024-03-16",
    "ease_factor": 2.5,
    "reviews": 0
  }
}

After each review:
- Correct → increase interval (×ease_factor)
- Incorrect → reset to 1 day

5. Verification

Before marking "mastered":
- Generate 5 questions covering concept
- User must answer 4/5 correctly
- Track in progress.md (topic folder)

6. Configuration

In ~/learn/config.json:

{
  "depth": "standard",
  "learner_type": "practical",
  "daily_review_limit": 20
}
