@VincentLogic: /teach revolutionized my three years of learning methods

A single /teach just crushed three years of my learning strategies.

I’ve gone through three phases when it comes to learning something.

The earliest phase was just reading documentation. White papers, official specs—page by page. By chapter three, my mind would wander. By chapter five, I’d already forgotten what chapter one was about. But back then, that was the only option.

Then came the era of LLMs. I’d throw unfamiliar concepts at ChatGPT and dig in with follow-up questions. That was indeed faster than grinding through documents. But there’s a catch—you have to know how to ask questions, know what to ask next, and know where your blind spots are. Essentially, you’re still driving the learning pace.

Now I’ve discovered a third mode.

Claude Code with a /teach skill. I tell it, “teach me agent fundamentals.” It first asks why I’m learning and what my current level is. Then it goes off to fetch resources, plans a curriculum path, and walks me through lesson by lesson.

The biggest difference from the previous two approaches: the initiative has flipped.

It’s not you grinding through docs. It’s not you coming up with questions to ask. It’s the AI guiding you. It introduces new concepts when needed, throws quizzes at you when appropriate. It remembers when you answered a question wrong last time, and the next time you chat, it knows exactly where you left off.

It even generates interactive HTML courseware—with progress bars, audio playback, and mini-quizzes. It’s not just dumping a wall of text on you; it’s actually “teaching a class.”

Twenty minutes a day, one lesson at a time with it, and it’s way more efficient than grinding through documentation for two hours on your own.
