- getFollowers (not available)
- getFollowing (not available)
- getHashtagAnalytics (not available)

## Priority Fixes Needed

1. Parameter Validation:

// Implement for getUserTimeline, searchTweets, getLikedTweets
interface TwitterParamValidator {
  validateTimelineParams(params: any): boolean;
  validateSearchParams(params: any): boolean;
  validateLikedTweetsParams(params: any): boolean;
}

2. Error Handling:

// Enhance error handling for 400 errors
interface TwitterErrorHandler {
  handle400Error(endpoint: string, params: any): void;
  logErrorDetails(error: any): void;
  suggestParameterFixes(params: any): string[];
}
