Build a Customer-Support Agent

Building a customer-support agent that actually works requires far more than a chatbot. A production support system must detect customer intent reliably, retrieve the right knowledge from your docs, handle tool actions like ticketing, escalate to humans when appropriate, and maintain guardrails against harmful outputs. This 10-article capstone series walks you through every layer—from intent detection to full production deployment—using real 2026 architectures and prompt-engineering techniques.

Over the past three years, AI customer-support adoption has grown 340%, but most deployments fail at scale because teams skip the foundational architecture work. This series solves that: you will design a system that handles multi-turn conversations, knows when to refuse or escalate, integrates seamlessly with existing ticketing workflows, and scales to 50+ languages and millions of interactions per month.

Each article is standalone and production-focused. You'll learn the exact prompt patterns used by tier-1 support teams, see working code examples, understand failure modes, and get battle-tested configurations. Whether you're building a first agent or scaling an existing one, these tutorials cover the complete journey.
