| description | Use when building production NLP systems, implementing text processing pipelines, developing language models, or solving domain-specific NLP tasks like named entity recognition, sentiment analysis, or machine translation. Specifically:\n\n<example>\nContext: E-commerce platform needs to automatically categorize customer reviews into product categories and extract sentiment\nuser: "We have 500K customer reviews. Build an NLP pipeline to categorize them by product and extract sentiment with confidence scores"\nassistant: "I'll build a multi-task NLP pipeline: first train a text classifier for product categorization (targeting F1 > 0.88), then implement sentiment analysis with aspect-based capabilities. Pipeline includes preprocessing, tokenization, multilingual support for international reviews, and real-time inference optimized for sub-100ms latency per review."\n<commentary>\nInvoke nlp-engineer when you need to build end-to-end production NLP pipelines combining multiple tasks (classification, extraction, sentiment). This differs from data-scientist (who analyzes text data) by focusing on building deployable NLP systems.\n</commentary>\n</example>\n\n<example>\nContext: Healthcare company needs to extract medical entities (drugs, symptoms, procedures) from patient notes for structured data\nuser: "Extract medical entities from unstructured patient notes automatically. We need high precision for critical medications and procedures"\nassistant: "I'll implement a multilingual NER system with domain-specific entity types. Solution includes custom training on your medical data, active learning for challenging cases, post-processing rules for validation, and confidence scoring. Model optimized to <1GB with 95ms inference latency for integration into your clinical workflow."\n<commentary>\nUse nlp-engineer when implementing specialized NLP tasks like named entity recognition with domain-specific requirements. The agent handles model selection, training, optimization, and production deployment.\n</commentary>\n</example>\n\n<example>\nContext: SaaS platform supports users in 15 languages and needs intelligent translation and localization\nuser: "Implement machine translation and localization for our product supporting 15 languages. Quality must be domain-aware and fast"\nassistant: "I'll design a translation system using fine-tuned MT models with domain adaptation, implement language detection for automatic routing, add back-translation for quality assurance, and optimize for real-time serving. Includes fallback strategies, terminology management, and monitoring for translation quality drift across languages."\n<commentary>\nInvoke nlp-engineer for complex multilingual NLP challenges requiring specialized architecture (translation, code-switching, locale management). The agent handles full pipeline design from architecture to production monitoring.\n</commentary>\n</example> |
