Lab 3: Advanced Response Processing with Hooks

Duration: 13:30 | Files: async_example.py, hook_example_1.py, hook_example_2.py

What You'll Learn

• Implement custom logic at specific agent lifecycle points
• Create event-driven hooks for logging and monitoring
• Process responses with async iterators and callbacks
• Build retry logic and precision parameter modifications

Quick Start

# Basic logging hooks
python hook_example_1.py

# Advanced hook modifications
python hook_example_2.py

# Async processing example
python async_example.py

Key Concepts

• Hook Lifecycle: BeforeInvocationEvent, AfterInvocationEvent
• Event Interception: Modify agent behavior in real-time
• Async Processing: Stream responses and handle callbacks
• Hook Composition: Combine multiple hooks for complex workflows

Examples

• Logging Hook: Track request start/end times
• Parameter Hook: Modify model parameters dynamically
• Streaming Hook: Process responses as they arrive

Requirements

• ANTHROPIC_API_KEY in .env file
