OpenClaw 评估

The README/skill description claims many advanced features (PDF extraction, image occlusion, auto-download media, tagging, integrations) but the bundled code only implements very simple Q/A parsing and TSV export — the capability claims and the actual implementation do not match.

# Anki Card Creator

## Overview

Intelligent flashcard generation tool that transforms medical study materials into Anki-compatible cards optimized for long-term retention through evidence-based spaced repetition.

**Key Capabilities:**
- **Multi-Format Input**: PDF textbooks, lecture slides, notes, web articles
- **Card Type Selection**: Basic, reversible, cloze deletion, image occlusion
- **Spaced Repetition Optimization**: Cards formatted for optimal review intervals
- **Automated Tagging**: Hierarchical organization by subject and topic
- **Media Integration**: Auto-download and embed relevant images
- **Batch Processing**: Convert entire chapters or courses efficiently

## When to Use

**✅ Use this skill when:**
- Preparing for medical board exams (USMLE, MCAT, specialty boards)
- Memorizing drug names, mechanisms, and side effects
- Learning anatomy structures and relationships
- Retaining biochemical pathways and reactions
- Creating pathology differential diagnosis cards
- Converting lecture notes to active recall format
- Building comprehensive review decks from textbooks

**❌ Do NOT use when:**
- Learning conceptual understanding → Use textbooks/videos first
- Memorizing without context → Ensure comprehension before card creation
- Creating cards for rapidly changing information → Use current resources
- Substituting clinical experience → Cards supplement, not replace practice
- Complex procedural skills → Use simulation or hands-on training

**Integration:**
- **Upstream**: `abstract-summarizer` (textbook chapter condensation), `pdf-text-extractor` (content extraction)
- **Downstream**: `anki-sync-server` (cloud backup), `study-schedule-optimizer` (review planning)

## Core Capabilities

### 1. Cloze Deletion Generation

Create fill-in-the-blank cards from dense text:

```python
from scripts.card_creator import AnkiCardCreator

creator = AnkiCardCreator()

# Generate cloze cards from text
text = """
Acute inflammation is characterized by five cardinal signs: 
redness (rubor), heat (calor), swelling (tumor), pain (dolor), 
and loss of function (functio laesa). These result from 
vasodilation, increased vascular permeability, and leukocyte 
infiltration.
"""

cards = creator.create_cloze_cards(
    text=text,
    n_cards=3,  # Generate 3 cards from this text
    difficulty="intermediate",
    tags=["Pathology", "Inflammation", "General_Pathology"]
)

# Output format (Anki-compatible)
# Card 1: "Acute inflammation is characterized by {{c1::five}} cardinal signs..."
# Card 2: "...signs: {{c1::redness}} (rubor), {{c2::heat}} (calor)..."
```

**Cloze Strategies:**
| Strategy | Use Case | Example |
|----------|----------|---------|
| **Single Deletion** | Key facts | "The {{c1::liver}} is the largest internal organ" |
| **Multiple Deletions** | Lists/groups | "CRAB symptoms: {{c1::Calcium}}, {{c2::Renal}}, {{c3::Anemia}}, {{c4::Bone}}" |
| **Hierarchical** | Progressive detail | "{{c1::Metformin}} is a {{c2::biguanide}} that {{c3::decreases hepatic glucose production}}" |

### 2. Basic and Reversible Cards

Generate question-answer pairs:

```python
# Create basic cards
cards = creator.create_basic_cards(
    content={
        "What is the mechanism of action of penicillin?": 
            "Inhibition of bacterial cell wall synthesis by binding to PBPs",
        "What are the major side effects of ACE inhibitors?":
            "Dry cough, hyperkalemia, angioedema, hypotension"
    },
    reversible=True,  # Create reverse cards too
    tags=["Pharmacology", "Antibiotics"]
)
```

**Card Types:**
- **Basic**: Question → Answer
- **Reversible**: Both directions (Q→A and A→Q)
- **Type-in**: Student types answer for active recall
- **Hint Cards**: Progressive disclosure with hints

### 3. Image Occlusion Cards

Create visual learning cards from diagrams:

```python
# Image occlusion for anatomy
cards = creator.create_image_occlusion(
    image_path="brachial_plexus.png",
    occlude_regions=[
        {"label": "Musculocutaneous nerve", "coords": (120, 200, 200, 240)},
        {"label": "Median nerve", "coords": (300, 250, 380, 290)},
        {"label": "Ulnar nerve", "coords": (400, 280, 480, 320)}
    ],
    card_type="one_by_one"  # or "all_at_once"
)
```

**Occlusion Types:**
- **One by One**: Reveal structures progressively
- **All at Once**: Identify all occluded regions
- **Transparent**: Hint visible through occlusion
- **Colored**: Different colors for different structures

### 4. Smart Tagging and Organization

Automatically organize cards into logical hierarchies:

```python
# Auto-tag based on content
cards = creator.process_textbook_chapter(
    chapter_text=pathoma_chapter,
    source="Pathoma - Hematopoiesis",
    auto_tag=True,
    tag_hierarchy=[
        "Pathoma",
        "{{chapter_name}}",
        "{{section_name}}"
    ]
)

# Results in tags like:
# Pathoma::Hematopoiesis::Red_Cell_Disorders
# Pathoma::Hematopoiesis::White_Cell_Disorders
```

**Tagging Strategies:**
- **Source-based**: First Aid, Pathoma, Sketchy
- **Subject-based**: Anatomy, Physiology, Pharmacology
- **Exam-based**: USMLE_Step1, Step2_CK, Shelf_Exams
- **Difficulty**: High_Yield, Medium_Yield, Low_Yield

## Common Patterns

### Pattern 1: Textbook Chapter Conversion

**Scenario**: Convert entire First Aid chapter to Anki deck.

```bash
# Extract and convert chapter
python scripts/main.py 
  --input first_aid_cardiology.pdf 
  --chapter "Ischemic Heart Disease" 
  --card-type cloze 
  --n-cards-per-page 3 
  --tags "First_Aid::Cardiology::IHD" 
  --output ischemic_heart_disease.apkg

# Import directly to Anki
# File ready for import with media included
```

**Workflow:**
1. Read chapter for understanding first
2. Run conversion tool
3. Review generated cards for accuracy
4. Import to Anki
5. Study with standard spaced repetition

### Pattern 2: Drug Cards with Images

**Scenario**: Create comprehensive pharmacology cards.

```python
# Generate drug cards with mechanisms
drugs = [
    {
        "name": "Metformin",
        "class": "Biguanide",
        "mechanism": "Activates AMPK, decreases hepatic gluconeogenesis",
        "indications": "Type 2 diabetes, PCOS",
        "side_effects": "GI upset, lactic acidosis (rare), B12 deficiency",
        "image": "metformin_structure.png"
    }
]

cards = creator.create_drug_cards(
    drugs=drugs,
    include_structures=True,
    include_mechanism_diagrams=True,
    tags=["Pharmacology", "Diabetes", "First_Line"]
)
```

**Card Format:**
```
Front: Metformin - Class?
Back: Biguanide
Tags: Pharmacology::Diabetes::First_Line

Front: Metformin - Mechanism?
Back: Activates AMPK → decreases hepatic gluconeogenesis
Image: [mechanism diagram]
Tags: Pharmacology::Diabetes::Mechanism

Front: Metformin - Side effects?
Back: GI upset, lactic acidosis (rare), B12 deficiency
Tags: Pharmacology::Diabetes::Side_Effects
```

### Pattern 3: Pathology Differential Cards

**Scenario**: Create cards for differential diagnosis practice.

```python
# Differential diagnosis cards
cards = creator.create_differential_cards(
    condition="Cough with hemoptysis",
    differentials=[
        {"diagnosis": "Lung cancer", "key_features": "Smoker, weight loss, mass on CT"},
        {"diagnosis": "TB", "key_features": "Immigrant, night sweats, cavitary lesion"},
        {"diagnosis": "PE", "key_features": "Sudden onset, tachypnea, D-dimer elevated"},
        {"diagnosis": "Bronchiectasis", "key_features": "Chronic cough, purulent sputum, dilated airways"}
    ],
    card_type="compare_contrast"
)
```

**Card Types:**
- **Feature → Diagnosis**: "Smoker + hemoptysis + weight loss → ?"
- **Diagnosis → Features**: "Lung cancer presentation?"
- **Compare**: "Differentiate lung cancer vs TB"

### Pattern 4: Lecture Notes to Cards

**Scenario**: Convert professor's lecture slides to study cards.

```bash
# Process lecture PDF
python scripts/main.py 
  --input lecture_slides.pdf 
  --source "Dr_Smith_Cardiology_Lecture_5" 
  --card-type mixed 
  --extract-images 
  --auto-tag 
  --output cardiology_lecture_5.apkg

# Review and edit in Anki
# Delete low-yield cards
# Add personal mnemonics
```

**Post-Processing Tips:**
- Delete obvious or overly simple cards
- Merge redundant cards
- Add personal memory hooks
- Suspend low-yield topics

## Complete Workflow Example

**Building comprehensive USMLE Step 1 deck:**

```bash
# Step 1: Process multiple sources
python scripts/main.py 
  --input first_aid_pathology.pdf 
  --source "First_Aid_2024" 
  --card-type cloze 
  --tags "First_Aid::Pathology" 
  --output fa_pathology.apkg

python scripts/main.py 
  --input sketchy_pharm.pdf 
  --source "Sketchy_Pharm" 
  --card-type basic 
  --include-images 
  --tags "Sketchy::Pharm" 
  --output sketchy_pharm.apkg

# Step 2: Merge decks
python scripts/main.py 
  --merge fa_pathology.apkg sketchy_pharm.apkg 
  --output usmle_step1_master.apkg

# Step 3: Add leech tags for difficult cards
python scripts/main.py 
  --input usmle_step1_master.apkg 
  --tag-leeches 
  --leech-threshold 8 
  --output usmle_step1_tagged.apkg
```

**Python API:**

```python
from scripts.card_creator import AnkiCardCreator
from scripts.importers import PDFImporter

# Initialize
creator = AnkiCardCreator()
importer = PDFImporter()

# Import and process textbook
content = importer.import_pdf(
    path="robbins_pathologic_basis_of_disease.pdf",
    pages="150-200",  # Inflammation chapter
    extract_images=True
)

# Create cloze cards
cards = creator.create_cloze_cards(
    text=content.text,
    images=content.images,
    n_cards=50,
    difficulty="advanced",
    tags=["Robbins", "General_Pathology", "Inflammation"]
)

# Add image occlusion for diagrams
for diagram in content.diagrams:
    occlusion_cards = creator.create_image_occlusion(
        image=diagram,
        auto_detect_labels=True
    )
    cards.extend(occlusion_cards)

# Export Anki package
creator.export_apkg(
    cards=cards,
    deck_name="Robbins_Inflammation",
    output_path="robbins_inflammation.apkg"
)

print(f"Created {len(cards)} cards ready for Anki import")
```

## Quality Checklist

**Card Quality:**
- [ ] One fact per card (atomicity)
- [ ] Clear, unambiguous questions
- [ ] Answers specific and complete
- [ ] Cloze deletions don't give away answer
- [ ] Images high resolution and relevant
- [ ] Tags hierarchical and consistent

**Educational Value:**
- [ ] Cards test high-yield information
- [ ] Difficulty appropriate for level
- [ ] Connections between related concepts
- [ ] Clinical context included where relevant
- [ ] No duplicate or near-duplicate cards

**Technical Quality:**
- [ ] Valid Anki format (import tested)
- [ ] Media files properly linked
- [ ] UTF-8 encoding for special characters
- [ ] CSS styling readable on mobile
- [ ] Card types appropriate for content

**Before Study:**
- [ ] **CRITICAL**: Review cards for accuracy
- [ ] **CRITICAL**: Delete cards for mastered material
- [ ] Personalize with own mnemonics
- [ ] Adjust card order if needed
- [ ] Set appropriate daily review limits

## Common Pitfalls

**Content Issues:**
- ❌ **Too much information** → "Cramming" cards with multiple facts
  - ✅ One concept per card; break complex topics into multiple cards

- ❌ **Memorization without understanding** → Memorizing without context
  - ✅ Include "why" and clinical significance

- ❌ **Outdated information** → Old guidelines or disproven theories
  - ✅ Verify against current textbooks and guidelines

**Card Design Issues:**
- ❌ **Ambiguous clozes** → "The {{c1::liver}} produces {{c2::bile}}" (which one is being asked?)
  - ✅ Clear question: "The liver produces ?" or "What organ produces bile?"

- ❌ **Overlapping cards** → Testing same fact multiple ways
  - ✅ Merge redundant cards; each fact tested once optimally

- ❌ **Recognition vs. recall** → Cards too easy (recognition only)
  - ✅ Use cloze deletions and type-in cards for active recall

**Study Strategy Issues:**
- ❌ **Too many new cards** → 100+ new cards/day leads to burnout
  - ✅ Sustainable pace: 20-30 new cards/day

- ❌ **No review of missed cards** → Ignoring leeches
  - ✅ Tag and review difficult cards separately

- ❌ **Passive card creation** → Making cards without studying
  - ✅ Create cards for immediate use; don't build massive backlog
