Claude Code Mastery 2026: Agentic Engineering Bootcamp — Subagents, Skills, MCPs, Hooks & Plugins

Stop scratching the surface. Become a Claude Code power user.

Claude Code is rewriting how software gets built — but most developers are using less than 20% of it. They prompt it like a chatbot, accept the first answer, and miss the features that turn it from an assistant into a teammate that ships production work autonomously.

Claude Code Mastery 2026 is a practical, no-filler bootcamp that takes you from casual user to confident agentic engineer. Every concept is taught the same way: what the feature is, why it exists, and how to use it on a real project. No toy examples. No black boxes.

What you'll master

• Context engineering — write prompts and CLAUDE.md files that produce high-quality results on the first try
• Plan Mode — make Claude think and design before any code is touched
• Custom Subagents — build specialist agents (Explore, CodeReviewer, TestRunner, Refactorer, Migrator) that work in parallel
• Agent Skills — package reusable workflows triggered automatically or via slash commands
• MCP Servers — connect Claude Code to GitHub, databases, browsers and any internal API; build your own in TypeScript
• Hooks — automate formatting, block dangerous commands, and enforce conventions at every tool call
• Plugins — bundle agents, skills, hooks and commands into one shareable install
• Ralph Loops — run Claude unattended with mechanical guardrails until tests pass
• Browser Feedback — close the visual loop with Playwright MCP for UI work
• Beyond the CLI — Claude Code Web (cloud), Desktop, mobile dispatch, remote control, Telegram channels & cron-style scheduled agents

Who this course is for

• Developers already using Claude Code who want to unlock the advanced features
• Engineers who keep hearing "subagents", "MCPs", "hooks", "Ralph loops" and want a clear, hands-on path to using them
• Senior engineers and leads who want to standardize an agentic engineering workflow for their team
• Anyone preparing for the new wave of "AI tooling engineer" / "agentic engineer" roles

You don't need prior AI experience. You need basic programming skills, a Claude Code subscription, and a terminal.

What you'll build

• A tuned local Claude Code setup (settings.json, CLAUDE.md, permission profiles)
• Four production-grade custom subagents you can drop into any repo
• Two custom Agent Skills (release-notes generator, migration-notes logger)
• A custom MCP server in TypeScript exposing a real third-party API
• A working Ralph loop with cost, iteration and stuck-loop guardrails
• A complete capstone — a real SaaS feature shipped end-to-end on an open-source app, including tests, code review and a deployed preview

What makes this course different

Every lesson is built around real projects, real commands, real diffs. Each one ends with a "Try it" exercise so you build muscle memory, not just understanding. By the end you'll have a complete mental model for treating Claude Code as a professional engineering tool — and a public portfolio that proves it.

Requirements

• Basic programming experience
• A Claude Code subscription (Pro or higher recommended)
• A terminal and a code editor
