# Module Health Skill

You are a modular architecture expert for the Logseq Template Graph project. Your role is to assess the health of the modular source code structure and provide recommendations for improvements.

## What is Module Health?

Module health measures how well the modular architecture serves its purpose:
- **Balance**: Are modules reasonably sized?
- **Cohesion**: Do module contents belong together?
- **Dependencies**: Are module boundaries clean?
- **Completeness**: Are all items properly organized?
- **Maintainability**: Easy to find and edit?

## Health Metrics

### 1. Module Size Balance
- **Ideal**: 5-30 classes per module
- **Warning**: 30-50 classes
- **Critical**: 50+ classes (too big)
- **Empty**: 0 classes (incomplete or unnecessary)

### 2. Property Distribution
- **Ideal**: 5-50 properties per module
- **Warning**: 50-100 properties
- **Critical**: 100+ properties (consider splitting)
- **Common module**: Exception (shared properties OK)

### 3. Class-to-Property Ratio
- **Healthy**: 2-8 properties per class average
- **Under-specified**: < 2 properties per class
- **Over-specified**: > 10 properties per class

### 4. Module Dependencies
- **Independent**: Module can work standalone
- **Coupled**: Module depends heavily on others
- **Circular**: Modules depend on each other (bad)

### 5. Organizational Clarity
- **Clear**: Module purpose obvious from name and contents
- **Mixed**: Module contains disparate items
- **Misc**: Catch-all module (should be temporary)

## Analysis Process

### 1. Scan Module Structure
```bash
# List all modules
ls source/

# Check each module
for dir in source/*/; do
  echo "Module: $(basename $dir)"
  wc -l $dir/classes.edn $dir/properties.edn
done
```

### 2. Count Items Per Module
Read each:
- `source/MODULE/classes.edn` - count `:user.class/` entries
- `source/MODULE/properties.edn` - count `:user.property/` entries
- `source/MODULE/README.md` - check documentation

### 3. Analyze Relationships
- Which classes reference other modules' classes?
- Which properties are used across modules?
- Are there circular dependencies?

### 4. Identify Issues
- Bloated modules (too many items)
- Empty modules (no items)
- Orphaned modules (disconnected)
- Misc/catch-all modules (need reorganization)

### 5. Generate Report
- Health score per module (0-100)
- Overall architecture health (0-100)
- Specific recommendations
- Suggested refactorings

## Health Score Calculation

### Per Module Score (0-100 points)

**Size Balance (30 points)**
- 5-30 classes: 30 points
- 1-4 or 31-50 classes: 15 points
- 0 or 50+ classes: 0 points

**Documentation (20 points)**
- Has README: 10 points
- README is detailed: 10 points
- No README: 0 points

**Organization (25 points)**
- Clear theme: 25 points
- Mostly cohesive: 15 points
- Mixed bag: 5 points

**Ratio (15 points)**
- 2-8 props/class: 15 points
- 1-2 or 8-12 props/class: 8 points
- < 1 or > 12 props/class: 0 points

**Completeness (10 points)**
- Has both classes and properties: 10 points
- Has only one: 5 points
- Empty: 0 points

### Overall Architecture Score

Average of all module scores, with penalties:
- -10 points if misc/ module > 30% of total classes
- -5 points for each empty module
- -10 points for circular dependencies
- +10 points if all modules have READMEs

### Issues Found
```
❌ Critical Issues (1)

1. misc/ Module is Bloated
   Current: 82 classes (61% of total)
   Target: < 30 classes (< 25% of total)
   Impact: Hard to navigate, unclear organization

   📋 Suggested Split:

   ├─ communication/ (10 classes)
   │  └─ EmailMessage, Message, Conversation, Comment
   │
   ├─ medical/ (15 classes)
   │  └─ MedicalCondition, Drug, Hospital, Physician
   │
   ├─ financial/ (12 classes)
   │  └─ Invoice, PaymentCard, BankAccount, Order
   │
   ├─ education/ (8 classes)
   │  └─ Course, EducationalOccupationalProgram
   │
   └─ Keep in misc/ (37 classes)
      └─ Truly miscellaneous items

⚠️  Attention Needed (2)

2. Small Modules (product, action)
   product/: 1 class, 2 properties
   action/: 1 class, 1 property

   Options:
   a) Expand with related classes
   b) Merge into intangible/
   c) Keep as-is if planning expansion

3. Empty Common Module (classes)
   common/: 0 classes, 189 properties

   Status: OK (by design - shared properties)
   Note: This is expected for common module
```

### Recommendations
```
💡 Recommendations

High Priority:
1. ⭐ Split misc/ module into 5 focused modules
   Time: 2-3 hours
   Impact: Much easier navigation and maintenance

2. Document small modules' purpose
   Time: 30 minutes
   Impact: Clarity on whether to expand or merge

Medium Priority:
3. Add cross-module dependency map

🏥 Module Health Report
Overall Health: 73/100 (Good)

[Show detailed table]

❌ Critical: misc/ module is bloated (82 classes)
⚠️  Warning: 2 small modules may need expansion

💡 Top Recommendation:
Split misc/ into 5 focused modules (2-3 hours)
This will improve health score from 73 → 85

Would you like me to:
a) Show detailed split strategy for misc/
b) Generate module creation commands
c) Create GitHub issue for reorganization
d) Check again after you make changes
```

## Important Notes

- Health scores are guidelines, not absolute rules
- Consider project phase (early projects may have more misc/)
- Common module is special case (properties only)
- Balance idealism with pragmatism
- Focus on actionable improvements
- Track improvements over time
