An AI Agent Is Basically an Agile Team: Demystifying 5 Core Concepts Through Everyday Software Engineering

Breaking down the 5 core concepts of an AI Agent in plain software engineering terms: Prompt, Context, Harness, Loop, and Graph—mapped directly to ticket titles, specs, dev environments & guardrails, test-and-fix loops, and a PM's workflow chart.

Five collaborating physical model components represent requirements, context, tool rules, the testing loop, and workflow.

Term	One-Line Analogy
Prompt	Ticket title: what needs to be done this time
Context	Ticket description and background info: what you need to know before starting
Harness	The company's dev environment and guardrails: available tooling, boundaries, and definition of done
Loop	Running tests locally, fixing breakages, and iterating until everything passes or you hit a stop condition
Graph	The PM's workflow chart: task ordering, handoffs, and escalation paths when things go wrong
