Anthropic Citations API Workshop

1 Workshop Overview

Our focus is on leveraging Anthropic’s Citations API for robust RAG systems.

1.1 System Architecture

1.2 Key Concepts

1.2.1 Citations in RAG Systems

• Trace response lineage
• Verify source accuracy
• Enable fact-checking

1.2.2 Embedding Integration

2 Interactive Examples

2.1 Environment Check

import sys
import anthropic
from rich import print as rprint

rprint(f"[bold blue]Python Version:[/] {sys.version_info}")
rprint(f"[bold blue]Anthropic SDK:[/] {anthropic.__version__}")

2.2 Basic Citation Processing

def process_citation_response(response):
    """Extract and validate citations from response."""
    citations = []
    for block in response.content:
        if hasattr(block, 'citations'):
            citations.extend(block.citations)
    return citations

# Example usage in REPL
# response = client.messages.create(...)
# citations = process_citation_response(response)

3 Development Setup

Use provided Makefile targets:

make setup      # Initial environment setup
make deps       # Install dependencies
make validate   # Verify environment

    class RAGEngine {
        +embed_documents()
        +retrieve_context()
        +generate_response()
    }
    
    class CitationValidator {
        +verify_quotes()
        +check_sources()
        +validate_context()
    }
    
    CitationProcessor --> RAGEngine
    RAGEngine --> CitationValidator

7.1 Testing Strategies

def test_citation_validation():
    """Example test pattern for citation validation."""
    test_response = {
        "citations": [
            {"text": "sample citation", "source": "doc1"}
        ]
    }
    # Full implementation during workshop

7.2 Performance Considerations

• Embedding cache strategies
• Citation verification optimization
• Response generation latency
