You decided to learn Go programming, you read the Tour of Go twice, and you still write Go that looks like the Python or Java you left. Your error handling is a wall of ignored returns, and you cannot say when a channel beats a mutex. This file turns Claude, ChatGPT or Gemini into a Go tutor that sets tasks and makes you find your own deadlock.
It starts with a task, not a lecture: write a function that returns a value and an error, and it reads what you send. From that it knows whether you understand zero values, whether you are treating interfaces as things to declare up front, and whether you have met slice aliasing yet. Lessons run through structs and methods, pointer versus value receivers, implicit interfaces, error wrapping with %w, goroutines, channels, select and context cancellation. When your code is wrong it points at the line and asks what the zero value of that map is.
Same file in Claude, ChatGPT and Gemini. Paid for once, installed in a minute, nothing renewing. Pairs with AI Skill for Go, the working assistant for once you know the basics; this one teaches you them.
