## 🎯 Capability Extraction Analysis

### Extraction Criteria

Based on the ComposableRepositoryParadigm, capabilities should be extracted when they meet these criteria:

1. **Self-Contained Functionality**: Can operate independently with minimal dependencies
2. **Reusability**: Could be useful in other projects or contexts
3. **Clear Boundaries**: Has well-defined interfaces and responsibilities
4. **Test Coverage**: Has adequate test coverage (>80% preferred)
5. **Size**: Significant enough to warrant extraction (>3 files or >500 LOC)
6. **Domain Separation**: Represents a distinct domain or concern

### Current Extraction Status

#### ✅ **Already Extracted** (2 capabilities)
- `markitect-content` - Content matter parsing (frontmatter, contentmatter, tailmatter)
- `markitect-utils` - General utility functions (test capability)

#### 🎯 **Recommended for Extraction** (7 capabilities)

| Priority | Capability | Rationale | Complexity | Dependencies |
|----------|------------|-----------|------------|-------------|
| **HIGH** | `markitect-finance` | Complete financial tracking system, self-contained | High | Low |

## 📋 Core MarkiTect Capabilities (Remain in Main Project)

### Core Architectural Paradigms

#### 1. Parse-Once, Manipulate-Many Architecture™
**Paradigm**: Single parsing operation creates multiple access pathways for document manipulation.

**Innovation**: Traditional markdown processors re-parse content for each operation. MarkiTect parses once and creates multiple fast-access representations:
- **AST Cache**: JSON-serialized Abstract Syntax Tree for lightning-fast loading
- **Database Metadata**: Structured front matter and document metadata
- **Original Content**: Preserved for integrity validation

#### 2. Database-First Metadata Management
**Paradigm**: Document metadata is treated as first-class relational data, not file-system artifacts.

#### 3. Performance-Validated Caching System
**Paradigm**: Cache performance is continuously validated against benchmarks, not assumed.

#### 4. TDD8 Methodology Integration
**Paradigm**: Issue-driven development with 8-step validation cycles.

### Core System Components

#### 🗄️ Database & Storage
- Database initialization and schema management
- Markdown file storage with metadata tracking
- SQL query execution with safety constraints
- Performance optimizations for large datasets

#### 📝 Markdown Processing
- Core AST conversion and manipulation
- Document modification through AST
- Roundtrip integrity validation
- Performance-optimized parsing

#### 🚀 Performance & Caching
- AST caching system with smart invalidation
- Performance benchmarking and validation
- Memory usage optimization
- Bulk operation efficiency

#### 🖥️ CLI Framework
- Command-line interface foundation
- Configuration management
- Error handling and validation
- Output formatting

#### 🔧 System Integration
- Configuration validation
- Environment detection
- Network connectivity
- File system validation
