AI Coding Agents Advanced Guide: Subagents, Skills, MCP, LSP, Commands, AGENTS.md, Hooks Explained

In this guide I show you how to use subagents, skills, mcp, slash commands, lsp and hooks. So you will learn how to use Claude Code, OpenCode and Codex AI coding agents and similar AI coding agents to their full potential. Specifically we will look at how you can make subagents handle complex tasks autonmously, how you can extend you ai agent with agent skills and slash commands and how you can connect to MCP. This is a practical tutorial in which we will implement these concepts using opencode from scratch and create a game to show you my ai coding workflow.
