OpenCode Crash Course: A Practical Guide to AI-Assisted Coding with Agents, Skills, MCP Servers, and Free AI Models

By Greg Lim

Build real applications with AI without needing expensive coding models.

OpenCode Crash Course is a practical, hands-on guide to using OpenCode as an AI coding agent. Instead of focusing on theory, this book walks you through building a complete Next.js application called MoneyWise, featuring a landing page, mortgage repayment calculator, and compound interest calculator.

Along the way, you'll learn how to get better results from OpenCode even when working with free AI models.

Inside, you'll discover how to:

Install and configure OpenCodeGenerate and modify code with AIUse Build and Plan modes effectivelyCreate agent rules and project instructionsBuild reusable custom slash commandsUnderstand context windows and avoid context pollutionExtend OpenCode with Agent SkillsConnect external services using MCP serversCreate custom agents and sub-agentsDelegate tasks to specialized AI agentsUse AI to debug, improve, and secure your applicationStructure your workflow so AI produces more consistent results

Rather than simply asking AI to "build an app," you'll learn how to give it the right instructions, context, tools, and responsibilities.

Whether you're a developer exploring AI-assisted coding or someone looking for a practical introduction to coding agents, OpenCode Crash Course will help you move from simple prompting to a more structured and powerful AI development workflow.

Start building with OpenCode and discover how much you can accomplish with AI coding agents.
