A complete, practical guide to Claude Code, Anthropic's agentic coding tool — what it is, how it works, and how to use it on a real project, from requirement to commit. (40 minutes)

Every terminal and Claude Code session in this video is real: it was run on a small demo project while making the video (Claude Code 2.1.283, 27 September 2026). Only long folder paths were shortened.

WHAT YOU'LL LEARN
• What Claude Code is, and why an agentic coding tool is different from a chatbot
• The mental model: files, terminal, tests, Git, MCP tools, browser
• Installing on Windows, macOS, Linux and WSL, and your first session
• Working in the terminal and in VS Code (CLI vs. extension — who does what)
• The development loop on a real repository: inspect, plan, change, test, fix, review, commit
• Git and GitHub: branches, commits, pull requests, @claude with GitHub Actions, code review options
• Browser work with the Claude in Chrome extension — what it is and what it needs
• MCP (Model Context Protocol): transports, scopes and a live add/list/remove demo
• Data engineering: a data-quality gate and a real idempotency bug found and fixed
• Architecture/design vs. implementation, documentation, testing and debugging
• Large codebases, CLAUDE.md project instructions, settings, skills, hooks and subagents
• Command reference grouped by purpose
• Current models and pricing (subscriptions vs. API), verified 27 September 2026
• Security and permissions: modes, allow/ask/deny rules, safe practice
• An end-to-end demo: plan → tests first → implementation → run → docs → diff review → commit
