AI Agents and the New AI Vocabulary

AI has moved from chatbots that answer to agents that act. This course decodes the words everyone now uses (agent, harness, context engineering, tool use, MCP, prompt injection) and shows how they fit together, so you can use, judge and build agentic AI with confidence.
