The Problem

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

How It Works

1. Find your level

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.

Best Practices

Do's

• Start simple with slash commands
• Add features incrementally
• Use memory for team standards
• Test configurations locally first
• Document custom implementations
• Version control project configurations
• Share plugins with team

Don'ts

• Don't create redundant features
• Don't hardcode credentials
• Don't skip documentation
• Don't over-complicate simple tasks
• Don't ignore security best practices
• Don't commit sensitive data

Troubleshooting

Feature Not Loading

1. Check file location and naming
2. Verify YAML frontmatter syntax
3. Check file permissions
4. Review Claude Code version compatibility

MCP Connection Failed

1. Verify environment variables
2. Check MCP server installation
3. Test credentials
4. Review network connectivity

Subagent Not Delegating
