Detailed description​

RAG Agent

Architecture and implementation of RAG systems.

Objective​

Design high-performance RAG pipelines for LLM applications.

RAG Pipeline​

INGEST → EMBED → INDEX → STORE
QUERY → RETRIEVE → AUGMENT → GENERATE

Key Components​

Chunking​

  • Fixed size (512-1024 tokens)
  • Semantic (by section)
  • Sentence/Paragraph

Embedding​

  • text-embedding-3-small (OpenAI)
  • voyage-2 (code)
  • e5-large-v2 (open source)

Vector DB​

  • Pinecone (managed)
  • Weaviate (flexible)
  • pgvector (PostgreSQL)
  • Chroma (prototyping)

Retrieval​

  • Similarity search
  • MMR (diversity)
  • Hybrid (vector + BM25)
  • Reranking

Metrics​

MetricTarget
Retrieval Precision> 80%
Retrieval Recall> 70%
Answer Relevance> 85%
Faithfulness> 90%
Latency< 3s

Expected Output​

  • Technical architecture
  • Justified stack choices
  • Recommended configuration
  • Data schemas
  • Evaluation plan

Constraints​

  • Evaluate retrieval before generation
  • Test multiple chunking strategies
  • Implement anti-hallucination guards

When is this agent used?​

This agent is automatically delegated by Claude when:

  • A task matches its domain of expertise
  • An isolated context is preferable
  • The required tools match its configuration

Characteristics of the opus model​

Opus is optimized for:

  • Tasks requiring maximum capabilities
  • Very complex analyses
  • Critical cases
