Mastering OpenCode: AI Agents, Skills, MCP & Automation

About this course

“This course contains the use of artificial intelligence.” Every AI coding assistant ties you to one thing you didn't actually ask for: a single model, from a single company, forever. Use Claude Code, and you're on Claude. Use Copilot, and you're on OpenAI's models. The moment a better model launches - faster, cheaper, more accurate for exactly what you're building - you can't just try it. You have to abandon your entire tool and rebuild your workflow from zero, just to swap out the engine underneath it.

OpenCode fixes that. It's an open-source, terminal-native AI coding agent that separates the tool from the model entirely - install it once, and plug in whichever model you want underneath: Claude, GPT, Gemini, open-source models, even models running locally. No lock-in, no rebuilding your workflow every time a new model drops. And because it's open-source with its own model marketplace (OpenCode Zen), you can start building with free models today, with zero API keys and zero subscription.

This course takes you from zero to production with OpenCode - not just a features tour, but real, hands-on demos for every concept. You'll start by understanding exactly what OpenCode is, how it compares to Claude Code, Cursor, Copilot, and Amazon Q, and how its pricing model actually works (free core, bring-your-own-key, or OpenCode's own Go/Zen plans). Then you'll install it across every interface it offers - CLI/TUI, Desktop app, and VS Code extension — and build a real, working monitoring application from scratch, extending it step by step as you learn.

From there, you'll go deep into what makes OpenCode genuinely extensible. You'll learn OpenCode's slash commands and build your own custom commands, define project rules with AGENTS md file, install and use Skills, and understand how Tools and permissions work under the hood. You'll then combine all of it - rules, skills, tools, and agents — to rebuild your application the right way. A full section is de
