Use the official Claude Code documentation as the source of truth for installation, permissions, configuration, MCP, Skills, Agent SDK, and CLI behavior.
Official documentation: https://code.claude.com/docs/zh-CN/overview
Claude Code tutorial collection: https://www.cccode.dev/
Claude Code Chinese guide: https://cc.x-qu.com/guide/
Agent Skills Chinese handbook: https://agentskillsdev.com/
A practical learning order is: first conversation, CLAUDE.md project memory, permissions and Plan Mode, hooks, MCP, Skills, subagents, and finally team or CI workflows. Third-party tutorials are useful for examples, but product behavior should be checked against the official documentation.
Break the goal into input, action, and output before adding review checkpoints.
Keep examples, failure conditions, and review criteria so the tutorial stays reusable.
