  --pattern crud \
  --pattern repository \
  --framework nestjs

# Interactive generation
gemini-flow generate code "React dashboard component" \
  --interactive \
  --dry-run
```

async analyzePatterns(content: string, filePath: string): Promise<PatternMatch[]>
async detectArchitecture(files: string[], contents: Map<string, string>): Promise<ArchitecturalPattern[]>
extractCodingStyle(content: string): CodingStyle
async identifyFrameworks(files: string[], contents: Map<string, string>): Promise<FrameworkSignature[]>
```

### 2. **Code Generation Engine** (`src/core/code-generation-engine.ts`)

Features:
- Template processing with variable substitution
- Pattern application and combination

Key Methods:
```typescript
async generateCode(request: GenerationRequest): Promise<GeneratedCode>
async generateFromTemplate(request: GenerationRequest, templateName?: string): Promise<GeneratedCode>
async generateFromPatterns(request: GenerationRequest, patternTypes?: string[]): Promise<GeneratedCode>
async generateWithAI(request: GenerationRequest): Promise<GeneratedCode>
```

### 3. **Command Integration**

Both commands are fully integrated into the CLI:
- **LearnCommand** (`src/cli/commands/learn.ts`)
