Go from typing claude to orchestrating agents, hooks, skills, and MCP servers — with visual tutorials, copy-paste templates, and a guided learning path.
The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond.
You installed Claude Code. You ran a few prompts. Now what?
The official docs describe features — but don't show you how to combine them. You know slash commands exist, but not how to chain them with hooks, memory, and subagents into a workflow that actually saves hours.
There's no clear learning path. Should you learn MCP before hooks? Skills before subagents? You end up skimming everything and mastering nothing.
Examples are too basic. A "hello world" slash command doesn't help you build a production code review pipeline that uses memory, delegates to specialized agents, and runs security scans automatically.
You're leaving 90% of Claude Code's power on the table — and you don't know what you don't know.
How Claude How To Fixes This
This isn't another feature reference. It's a structured, visual, example-driven guide that teaches you to use every Claude Code feature with real-world templates you can copy into your project today.
| | Official Docs | This Guide |
|--|---------------|------------|
| Format | Reference documentation | Visual tutorials with Mermaid diagrams |
| Depth | Feature descriptions | How it works under the hood |
| Examples | Basic snippets | Production-ready templates you use immediately |
| Structure | Feature-organized | Progressive learning path (beginner to advanced) |
| Onboarding | Self-directed | Guided roadmap with time estimates |
| Self-Assessment | None | Interactive quizzes to find your gaps and build a personalized path |
What you get:
10 tutorial modules covering every Claude Code feature — from slash commands to custom agent teams
Copy-paste configs — slash commands, CLAUDE.md templates, hook scripts, MCP configs, subagent definitions, and full plugin bundles
Mermaid diagrams showing how each feature works internally, so you understand why, not just how
A guided learning path that takes you from beginner to power user in 11-13 hours
Built-in self-assessment — run /self-assessment or /lesson-quiz hooks directly in Claude Code to identify gaps
Take the self-assessment quiz or run /self-assessment in Claude Code. Get a personalized roadmap based on what you already know.
2. Follow the guided path
Work through 10 modules in order — each builds on the last. Copy templates directly into your project as you learn.
3. Combine features into workflows
The real power is in combining features. Learn to wire slash commands + memory + subagents + hooks into automated pipelines that handle code reviews, deployments, and documentation generation.
4. Test your understanding
Run /lesson-quiz [topic] after each module. The quiz pinpoints what you missed so you can fill gaps fast.
# 1. Clone the guide
git clone https://github.com/luongnv89/claude-howto.git
cd claude-howto
# 2. Copy your first slash command
mkdir -p /path/to/your-project/.claude/commands
cp 01-slash-commands/optimize.md /path/to/your-project/.claude/commands/
# 3. Try it — in Claude Code, type:
# /optimize
# 4. Ready for more? Set up project memory:
cp 02-memory/project-CLAUDE.md /path/to/your-project/CLAUDE.md
# 5. Install a skill:
cp -r 03-skills/code-review ~/.claude/skills/
Want the full setup? Here's the 1-hour essential setup:
Is this free?
Yes. MIT licensed, free forever. Use it in personal projects, at work, in your team — no restrictions beyond including the license notice.
Is this maintained?
Actively. The guide is synced with every Claude Code release. Current version: v2.3.0 (April 2026), compatible with Claude Code 2.1+.
How is this different from the official docs?
The official docs are a feature reference. This guide is a tutorial with diagrams, production-ready templates, and a progressive learning path. They complement each other — start here to learn, reference the docs when you need specifics.
How long does it take to go through everything?
11-13 hours for the full path. But you'll get immediate value in 15 minutes — just copy a slash command template and try it.
Can I use this with Claude Sonnet / Haiku / Opus?
Yes. All templates work with Claude Sonnet 4.6, Claude Opus 4.6, and Claude Haiku 4.5.
Can I contribute?
Absolutely. See CONTRIBUTING.md for guidelines. We welcome new examples, bug fixes, documentation improvements, and community templates.
Can I read this offline?
Yes. Run uv run scripts/build_epub.py to generate an EPUB ebook with all content and rendered diagrams.
