   - Implement rate limiting and queuing

2. Frontend Requirements:
   - Create notification components (bell icon, dropdown, list)
   - Implement real-time updates with WebSocket
   - Add notification preferences UI
   - Create notification history page
   - Add proper loading states and error handling
   - Implement responsive design

3. Testing Requirements:
   - Unit tests for all backend services
   - Integration tests for API endpoints
   - Component tests for React components
   - E2E tests for user workflows
   - Performance tests for notification delivery

4. Documentation:

   - Component documentation with Storybook
   - Setup and configuration guides
   - Troubleshooting documentation"

Legacy System Modernization

Phase 1: "Modernize authentication system:
- Replace sessions with JWT tokens
- Add OAuth2 integration
- Implement proper password policies
- Add two-factor authentication
- Maintain backward compatibility"

Phase 2: "Update database schema:
- Normalize existing tables
- Add proper indexes and constraints
- Implement data versioning
- Add audit logging
- Create migration scripts"

Continuous Integration Automation

Automated CI/CD Pipeline

Complete CI/CD setup task:

"Create comprehensive CI/CD pipeline:

1. Source Control Integration:
   - Set up branch protection rules
   - Configure automated code quality checks
   - Implement semantic versioning
   - Add automated changelog generation

2. Build Pipeline:
   - Multi-stage Docker builds
   - Parallel testing execution  
   - Code coverage reporting
   - Security vulnerability scanning
   - Performance benchmarking

3. Deployment Pipeline:
   - Blue-green deployment strategy
   - Database migration automation
   - Environment-specific configurations
   - Health checks and monitoring
   - Rollback mechanisms

4. Monitoring and Alerting:
   - Application performance monitoring
   - Error tracking and alerting
   - Resource usage monitoring
   - User experience metrics
   - Automated incident response"

Quality Assurance Automation

Code Maintenance Automation

Automated Refactoring

Continuous code improvement task:

"Implement automated code maintenance:

1. Code Quality Improvements:
   - Identify and fix code smells
   - Optimize performance bottlenecks
   - Update deprecated APIs and patterns
   - Improve error handling consistency
   - Enhance code documentation

2. Dependency Management:
   - Update outdated dependencies
   - Resolve security vulnerabilities
   - Remove unused dependencies
   - Optimize bundle sizes
   - Maintain compatibility

3. Technical Debt Reduction:
   - Refactor complex functions
   - Eliminate code duplication
   - Improve naming conventions
   - Add missing tests
   - Update outdated documentation

4. Monitoring and Reporting:
   - Generate code quality reports
   - Track technical debt metrics
   - Monitor performance trends
   - Alert on quality degradation
   - Provide improvement recommendations"

Automated Bug Detection and Fixing

Automated bug hunting:
"Scan codebase for common issues:
- Memory leaks and resource issues
- Race conditions and concurrency bugs
- Input validation vulnerabilities
- Logic errors and edge cases
- Performance antipatterns"

Smart bug resolution:
"Fix identified issues automatically:
- Apply standard fix patterns
- Add proper error handling
- Implement input validation
- Optimize resource usage
- Add regression tests"

Project Management Automation

Task Planning and Estimation

Automated project planning:

"Analyze project requirements and create detailed plan:

1. Requirement Analysis:
   - Break down features into user stories
   - Identify technical dependencies
   - Assess complexity and risks
   - Define acceptance criteria
   - Estimate development effort

2. Sprint Planning:
   - Organize tasks by priority
   - Balance team workload
   - Identify blockers and dependencies
   - Create realistic timelines
   - Define sprint goals

3. Resource Allocation:
   - Match tasks to team skills
   - Identify knowledge gaps
   - Plan for code reviews
   - Schedule testing activities
   - Allocate buffer time

4. Progress Tracking:
   - Set up automated progress reports
   - Monitor velocity and burndown
   - Track quality metrics
   - Identify risks early
   - Suggest timeline adjustments"
