What is it?

Claude Code Ultimate Guide is a multi-part reference for using Anthropic's Claude Code CLI beyond basic prompting. It covers installation and first tasks, core concepts such as context and memory, and engineering topics like agent harness design, loop and graph workflows, and when to choose a CLI, skill, agent, hook, plugin, or MCP server.

The repository holds Markdown sources for the complete guide, a cheatsheet, a guided learning path, and quizzes, along with runnable examples including agents, skills, hooks, CLAUDE.md templates, and workflows. Security sections address permissions, sandboxing, production safety, data privacy, and enterprise governance. Operational sections cover observability, team metrics, and cost calculation.

The project also ships a stdio MCP server that lets Claude Code, Codex, Cursor, and other MCP clients query the guide's content, plus machine-readable indexes such as llms.txt. The website is the primary reading interface, and community translations exist in Chinese, Ukrainian, and Spanish.
