# Task ID: 4
# Title: Implement Repomix Integration
# Status: pending
# Dependencies: 1, 3
# Priority: high
# Description: Develop the Repomix manager component to execute repomix for codebase flattening and analysis.
# Details:
1. Create RepomixManager class:
   ```typescript
   class RepomixManager {
     constructor(config: RepomixConfig) {
       // Initialize with configuration
     }
     
     async flattenCodebase(options: {
       codebaseRoot: string,
       includePatterns?: string[],
       excludePatterns?: string[]
     }): Promise<string> {
       // Execute repomix via child_process
       // Format output for optimal LLM consumption
       // Return flattened codebase content
     }
     
     async generateDiff(beforeSnapshot: string, afterSnapshot: string): Promise<string> {
       // Generate diff between two snapshots
     }
   }
   ```
2. Implement execution of repomix using Node.js child_process:
   ```typescript
   const { exec } = require('child_process');
   
   // Execute repomix command
   const command = `npx repomix ${options.codebaseRoot} ${includeFlags} ${excludeFlags}`;
   const result = await new Promise((resolve, reject) => {
     exec(command, { maxBuffer: 1024 * 1024 * 100 }, (error, stdout, stderr) => {
       if (error) reject(error);
       else resolve(stdout);
     });
   });
   ```
3. Add optimization for large codebases
4. Implement caching mechanism to avoid redundant processing
5. Add error handling for repomix execution failures

# Test Strategy:
Test repomix execution with various include/exclude patterns. Verify correct handling of large codebases. Test caching mechanism by measuring execution time for repeated calls. Test error handling by simulating repomix failures.
