"Did I build it right?" — the question every developer asks before shipping an AI app to production. At scale, getting it wrong gets expensive fast: the wrong partition key, the wrong index, the wrong data model — that's RUs burning in production.
Andrew Liu, Principal PM Manager for Azure Cosmos DB, shows how the Cosmos DB Agent Kit answers that question without waiting a week for a senior architect.
In this demo from Azure Cosmos DB Conf 2026, Andrew walks through a real multi-agent travel-planner app — a 5-day LA family trip assistant that remembers where you left off using short-term, long-term, and vector memory stored in Azure Cosmos DB. Then he runs a live, in-editor code review of the entire data layer.
You'll see:
• The Azure Cosmos DB VS Code extension — query, browse, and inspect your account inline, no portal context-switch
• Multi-agent memory patterns on Azure Cosmos DB: declarative facts, procedural preferences, episodic trip data, and vectors
• Installing the Cosmos DB Agent Kit with one CLI command — project or global scope
• How agent skills package decades of Azure Cosmos DB expertise (data modeling, partitioning, indexing, RU economics) as specialized context for your AI assistant
• A live review that reads your actual code AND your Bicep IaC — correlating partition keys, index policies, and document shapes against your real data access patterns
• Concrete findings: missing composite indexes on ORDER BY queries, a wrong partition key on the memories container, and a prioritized fix list ranked by RU savings
• Why catching this BEFORE production is the difference between a $50/month app and a runaway bill at scale
Two takeaways:
1. New to Azure Cosmos DB? You don't have to learn partitioning and data modeling alone — the Agent Kit gives you a senior architect on demand, in your editor.
2. Existing Azure Cosmos DB developer? Point it at your past projects and find performance and cost wins.
