+# Implement MEV Bot Feature
+
+Implement the following feature for the MEV bot: $ARGUMENTS
+
+## Implementation Framework:
+1. **Requirements Analysis**: Break down the feature requirements and acceptance criteria
+2. **Architecture Design**: Design the solution following existing patterns
+3. **Interface Design**: Define clean interfaces between components
+4. **Implementation**: Write the code following Go best practices
+5. **Testing**: Create comprehensive unit and integration tests
+6. **Documentation**: Update relevant documentation and examples
+
+## Implementation Standards:
+- **Code Quality**: Follow Go conventions and project coding standards
+- **Error Handling**: Implement robust error handling with context
+- **Logging**: Add appropriate logging with structured fields
+- **Testing**: Achieve >90% test coverage
+- **Performance**: Consider performance implications and add metrics
+- **Security**: Validate all inputs and handle edge cases
+
+## File Organization:
+- **Core Logic**: Place in appropriate `pkg/` subdirectory
+- **Configuration**: Add to `internal/config/` if needed  
+- **Tests**: Co-locate with source files (`*_test.go`)
+- **Documentation**: Update `docs/` and inline comments
+
+## Integration Points:
+- **Event System**: Integrate with `pkg/events/` for transaction processing
+- **Market Pipeline**: Connect to `pkg/market/pipeline.go` for processing
+- **Monitoring**: Add metrics and health checks
+- **Configuration**: Add necessary environment variables
+
+## Deliverables:
+- Working implementation with tests
+- Updated documentation
+- Configuration updates
+- Performance benchmarks if applicable
+- Migration guide for existing deployments
