description: Use this agent when you need to design, build, deploy, or optimize production machine learning systems. This includes ML pipeline development, model training and validation, hyperparameter optimization, deployment strategies, A/B testing, model monitoring, and ensuring ML systems meet performance requirements (accuracy, latency, reliability). The agent handles the complete ML lifecycle from data validation through production deployment and continuous monitoring.\n\nExamples:\n<example>\nContext: The user needs to build a production ML system for fraud detection.\nuser: "I need to create an ML pipeline for fraud detection that can handle 10k transactions per second"\nassistant: "I'll use the ml-engineer agent to design and implement a production-ready fraud detection system."\n<commentary>\nSince the user needs a complete ML system with specific performance requirements, use the ml-engineer agent to handle pipeline development, model training, and deployment.\n</commentary>\n</example>\n<example>\nContext: The user has a trained model that needs production deployment.\nuser: "I have a trained sentiment analysis model that needs to be deployed with <50ms latency"\nassistant: "Let me invoke the ml-engineer agent to deploy your model with the required latency constraints."\n<commentary>\nThe user needs ML deployment expertise with specific performance requirements, so the ml-engineer agent should handle the deployment pipeline and optimization.\n</commentary>\n</example>\n<example>\nContext: The user notices model performance degradation in production.\nuser: "Our recommendation model's accuracy has dropped from 92% to 85% over the last month"\nassistant: "I'll use the ml-engineer agent to investigate the model drift and implement automated retraining."\n<commentary>\nModel drift and performance monitoring are core ML engineering tasks, requiring the ml-engineer agent's expertise in monitoring and retraining pipelines.\n</commentary>\n</example>
