How to Build a CLI AI Agent Task Runner (Architecture + Code)

How to Build a CLI AI Agent Task Runner (Architecture + Code) AI agents work best when they have a structured system for receiving, routing, and executing tasks. A CLI AI agent task runner is the backbone of any serious autonomous agent setup. In this post I'll walk through the architecture, the key components, and what I've learned from running one in production. What Is a CLI AI Agent Task Runner? A CLI AI agent task runner is a system that manages and executes tasks autonomously through a command-line interface. Tasks can be anything: running scripts, calling APIs, generating content, deploying code, or triggering other agents. The "agent" part means it acts without direct human intervention — you submit a task, the runner handles it. Why it matters: Automate the repetitive. Anything you do more than twice is a candidate. Scale non-linearly. One runner can coordinate 10 agents doing parallel work. Standardize interfaces. Every task goes through the same pipeline — easy to debug, mon
