📚 Claude Code Learning Roadmap

New to Claude Code? This guide helps you master Claude Code features at your own pace. Whether you're a complete beginner or an experienced developer, start with the self-assessment quiz below to find the right path for you.

---

🧭 Find Your Level

Not everyone starts from the same place. Take this quick self-assessment to find the right entry point.

Answer these questions honestly:

• I can start Claude Code and have a conversation (claude)
• I have created or edited a CLAUDE.md file
• I have used at least 3 built-in slash commands (e.g., /help, /compact, /model)
• I have created a custom slash command or skill (SKILL.md)
• I have configured an MCP server (e.g., GitHub, database)
• I have set up hooks in ~/.claude/settings.json
• I have created or used custom subagents (.claude/agents/)
• I have used print mode (claude -p) for scripting or CI/CD

Your Level:

Checks	Level	Start At	Time to Complete
0-2	Level 1: Beginner — Getting Started	Milestone 1A	~3 hours
3-5	Level 2: Intermediate — Building Workflows	Milestone 2A	~5 hours
6-8	Level 3: Advanced — Power User & Team Lead	Milestone 3A	~5 hours

Tip

: If you're unsure, start one level lower. It's better to review familiar material quickly than to miss foundational concepts.

Interactive version: Run /self-assessment in Claude Code for a guided, interactive quiz that scores your proficiency across all 10 feature areas and generates a personalized learning path.

---

🎯 Learning Philosophy

The folders in this repository are numbered in recommended learning order based on three key principles:

1. Dependencies - Foundational concepts come first
2. Complexity - Easier features before advanced ones
3. Frequency of Use - Most common features taught early

This approach ensures you build a solid foundation while gaining immediate productivity benefits.
