Claude Code: Zero To Hero

Learn Claude Code end to end — from your first session to building products on the Agent SDK. Written for developers, DevOps, cloud, SRE, and platform engineers who want to actually use it, not just watch a demo.

Sixteen modules, four phases, a two-track capstone. Every fact is verified against Anthropic's official documentation, and every module carries the date it was last checked.

Course: trainwithshubham.ai · Language: English · Format: Self-paced · Verified: 2026-08-12

🚀 New to Claude Code Start at Module 1 and read in order
Already installed Skip to Module 4 — the loop and the tools
🔧 Here for DevOps/SRE Module 13 is the one written for you
🔍 Looking for one thing Topic index · Command reference
📋 Want the short version Quick reference — all 16 modules condensed
🩹 Something's broken Troubleshooting — symptom → cause → fix
Already good, want sharper Power moves — the compound techniques

The course

Phase 1 · Zero → Comfortable

Understand what you're using, and get it running.

# Module What you'll learn
01 Welcome to the Era of Agentic Coding What an agentic loop is, the 2026 model lineup, and which Claude surface to use
02 Prompt Engineering for Agentic Work Writing for an agent instead of a chatbot, and where instructions actually live
03 Installing Claude Code Everywhere Install on any OS, every platform compared, authentication, and the interface

Phase 2 · Comfortable → Productive

The tools, the guardrails, and how to extend both.

# Module What you'll learn
04 🔬 The Agentic Loop and Built-In Tools Read, Write, Edit, Grep, Glob, Bash, sandboxing, and the context window
05 🔬 Permissions, Memory, and Configuration Permission modes, auto mode, CLAUDE.md, auto memory, settings precedence
06 Planning and Executing a Real Project Plan mode, sessions and branching, checkpoints, and monorepos
07 🔬 Skills, Commands, and Hooks Extending Claude Code — and the one layer that's genuinely enforced
08 The Plugin Ecosystem Installing plugins, building a marketplace, and the two security plugins
09 🔬 MCP in 2026 Connecting external tools, tool search, and channels

Phase 3 · Productive → Advanced

Many agents, every surface, and the boundaries an organisation sets.

# Module What you'll learn
10 🔬 Subagents and Orchestration at Scale Subagents, agent teams, dynamic workflows, worktrees, cross-session messaging
11 Claude Code Across Every Surface VS Code, JetBrains, Desktop, web, routines, mobile, Remote Control, Slack, Chrome
12 CI/CD, Code Review, and Security Headless mode, GitHub Actions, the review ladder, and the security story end to end
13 Infrastructure, Cloud, and Enterprise IaC, third-party providers, self-hosted environments, gateway, admin, observability

Phase 4 · Advanced → Hero

Build with it, then build something with it.

# Module What you'll learn
14 🔬 Building Products with the Agent SDK The SDK, the message lifecycle, and hosting agents in production
15 Capstone: Choose Your Track Ship a full-stack feature, or build a self-healing ops agent
16 Staying Sharp: What's Next Reading the weekly changelog and maintaining your setup

🔬 = deep-dive module — longer, with hands-on exercises, common pitfalls, and key takeaways per chapter.

Everyone takes Modules 1–14. Module 15 splits into two tracks so a frontend developer and an SRE each leave with a portfolio piece that matches their job. Module 13 is not optional on either track — it's what makes this different from a generic AI coding tutorial.


Reference

Six ways to find something without reading a whole module:

Topic index A–Z concepts → the module that covers them, plus a "I want to…" table
Command reference Every slash command, CLI flag, and environment variable in the course
Quick reference All 16 modules condensed to bullets
Troubleshooting Symptom → cause → fix. Install, login, config not loading, performance
Power moves Compound techniques that combine several modules, plus the anti-patterns
Syllabus Full chapter-level outline of all 16 modules

How to use this

  • Read in order the first time. Modules build on each other — Module 7 makes much more sense after Module 5.
  • Every module ends with links to the previous and next one, so you can read straight through.
  • "Try it yourself" blocks assume a practice repo. See labs/ for what it needs to contain — or use any project of your own with a failing test in it.
  • Claude Code ships weekly. Each module carries a last_verified date in an HTML comment at the top. Anything version-specific — model IDs, prices, flags, command names — is worth a re-check before you rely on it for something critical. Module 16 covers how.

Contributing

Corrections are welcome, especially version drift — a command that was renamed, a flag that changed, a limit that moved. That's the most valuable kind of PR this repo can get.

Before opening one that touches module content:

  1. Verify against official docs. Start at code.claude.com/docs/llms.txt for the index and whats-new for recent changes. Third-party recap posts have been unreliable.
  2. Update the last_verified date in the module's HTML comment.
  3. Keep the references in sync — a change to a module usually needs the same change in reference/quick-reference.md, and sometimes in reference/commands.md.
  4. Don't state what you can't verify. If a fact isn't in the official docs, cut it rather than shipping it.

See CLAUDE.md for the full content conventions.
