Claude Code: Everything You Need to Know
A practical guide to Claude Code covering setup, prompt engineering, slash commands, skills, hooks, subagents, agent teams, and MCP servers, from first use to power-user depth.
This guide walks through Claude Code, Anthropic's command-line coding agent, from a first prompt to coordinating multiple agents. It explains what distinguishes Claude Code from a chat interface, reading a project's code, planning changes, editing files, running commands, and committing, all from the prompt line, and lays out a path for beginners through setup, prompt engineering, and a first skill, alongside deeper material on skills, hooks, subagents, dynamic workflows, agent teams, and MCP servers for developers who already use it.
It contrasts the five extension points in Claude Code, skills, hooks, subagents, workflows, and MCP servers, side by side, explaining when to reach for each one and where each lives in a project's configuration, and includes reference material such as a slash-command cheat sheet, effort levels, and a FAQ.
