Comment construire un agent d'achat AI avec Claude (build complet)

A complete build-along tutorial for creating an AI shopping agent using Claude's tool-use (function calling) capabilities.

What you'll build:

• A chat interface where shoppers ask about products
• The AI agent calling tools: `search_products`, `place_order`, `track_order`
• Real-time inventory and pricing queries
• Order placement directly from the chat

This is the same architectural pattern that modern AI shopping assistants use — function calling over a live catalog, not static training data.
