Developer toolsA practical Claude Code guide with clear mental models and copy-paste examples — setup, prompt engineering, slash commands, skills, hooks, subagents, agent teams, and MCP servers.
Overview
A practical guide to Claude Code — from your first prompt to multi-agent automation, hooks, MCP, and team workflows. Built around clear mental models and real examples, not marketing. Developers using (or about to use) Claude Code. Beginners get a guided path; power users get depth on Skills, Hooks, MCP, and Agent Teams. The four extension points in Claude Code, side by side: 💡 These four compose. Most polished workflows combine 2–3. Claude Code is Anthropic's official CLI for working with Claude from your terminal. You point it at a project; it reads the code, plans, edits files, runs commands, and commits — all from the prompt line. - — not pasted snippets. Claude sees your file tree, runs grep, follows imports, and grounds answers in real context. - — diff-aware edits, then pytest/vitest/go test on the spot to verify the change. - — slash commands, hooks, sub-agents, MCP servers, and your normal git/shell workflow.

Claude Code: Everything You Need to Know
Learn everything you need to use Claude Code well, one small step at a time, with Pip cheering you on.
Claude Code Quest is a learning app that opens in your browser beside Claude Code. It shows you one step, you try it in your own practice copy, and it checks your work and cheers when you get it right. Three levels take you from your first session to a setup your team shares.

Claude Code Quest opens in your browser (in a Codespace, open the address it prints). Keep a terminal beside it: Claude Code Quest tells you what to type there and checks each step.
Claude Code Quest has no AI in it and changes none of your work. Prefer to read? Every lesson works from its page alone.
Meet Pip
Pip works beside you. He cheers your wins, and the help gets lighter as you get the hang of each skill, until you do it on your own.
