Claude How To

Claude How To is an open-source, MIT-licensed guide that takes developers from basic Claude Code usage to advanced agent orchestration in 11–13 hours. It provides 10 progressive tutorial modules, Mermaid diagrams, production-ready copy-paste templates, and built-in self-assessment quizzes — filling the gap left by official feature-reference documentation. The guide covers every major Claude Code capability including slash commands, memory, skills, subagents, MCP servers, hooks, plugins, checkpoints, and CLI automation.

• 10 tutorial modules covering every Claude Code feature from beginner slash commands to advanced plugin bundles, organized in a progressive learning path with time estimates
• Copy-paste templates for slash commands, CLAUDE.md memory files, hook scripts, MCP configs, subagent definitions, and full plugin bundles ready to drop into any project
• Mermaid diagrams visually explaining how each feature works internally so you understand the why, not just the how
• Built-in self-assessment — run /self-assessment or /lesson-quiz [topic] directly in Claude Code to identify knowledge gaps and get a personalized roadmap
• Guided learning path with three entry levels (Beginner, Intermediate, Advanced) and estimated completion times per module
• Real-world workflow examples showing how to combine features into automated code review pipelines, CI/CD automation, documentation generation, security audits, and DevOps deployments
• EPUB generation via uv run scripts/build_epub.py for offline reading with all content and rendered diagrams
• Automated testing suite using pytest, Ruff, Bandit, and mypy to ensure all scripts and templates remain reliable across Python 3.10–3.12
• Multi-language support with README translations in English, Vietnamese, Chinese, and Ukrainian
• Actively maintained and synced with every Claude Code release; current version targets Claude Code 2.1+ and is compatible with Claude Sonnet 4.6, Opus 4.7, and Haiku 4.5

To get started: clone the repository, copy a slash command template into your project's .claude/commands/ directory, and type /optimize in Claude Code. Follow the learning roadmap for the full structured path.
