Show HN: AI Terminal Course – Learn AI Engineering Like Learning Vim (npmjs.com)

I spent months watching AI tutorials on YouTube. Took notes. Felt like I learned a ton. Then I sat down to build something and... couldn't. I didn't actually understand a lot of stuff!

The problem: Passive learning doesn't work for engineering skills.

What makes this different:

• You TYPE every command (no copy-paste) • You SEE real API responses (not fake demos) • You PAY real costs (~$10 total) • Terminal-only (no context switching)

Think vimtutor, but for AI engineering.

20 modules covering: - Tokens, embeddings, RAG - Structured outputs, tool calling, agents - Cost optimisation, evals, production monitoring - Real OpenAI/Anthropic API calls
