Episode 44 — Agents & Tool Use: When Models Act on Your Behalf

This episode examines AI agents, which extend models beyond text generation into action. Agents use planning and tool integration to execute tasks on behalf of users, such as querying databases, calling APIs, or chaining steps to solve complex problems. Certification exams may test whether learners can identify the difference between static model responses and dynamic agent behavior. Core concepts include orchestration, task decomposition, and safe execution boundaries.

Examples show how agents operate. A customer support agent might retrieve policy documents automatically, while a research assistant agent could search, summarize, and format results into a report. Troubleshooting concerns include reliability, where errors in planning cascade across steps, and safety, where tool access must be restricted to avoid misuse. Best practices involve sandboxing environments, monitoring outputs, and designing fallback mechanisms. Exam questions may describe multi-step workflows and require learners to determine whether an agent architecture is implied. By understanding agents and tool use, learners gain insight into the future of AI systems as active participants in workflows.
