Can we actually build the thing now?

说明与用途

使用 Gemini 和 Claude 实际模型的学习系统，生成最新、可测试的课程，并跟踪费用，提供交互式 CLI。

问题

Build a learning system that generates up‑to‑date, testable courses using real LLM calls and official documentation.

结果

The rebuilt learning system successfully generated a current, testable TypeScript course, demonstrated cost tracking, and allowed interactive learning via the learn CLI.

工作流

• Install learn tool via uv
• Run learn with a learning prompt
• Provide background and project details when prompted
• System builds course, fetching live docs and generating lessons
• User runs learn next to navigate lessons
• Use learn check to run tests on exercises
• Use learn hint for guidance
• Use learn solution to view answers
• Use learn quiz to answer questions
• Use learn review for spaced repetition

证据

The first iteration built by yours truly Claude Opus 5.5 had 235 tests, and every single one of them passed. But when I started poking ... I realized not one of those tests had ever talked to a real model

When I pointed it at a real model, it failed on the very first call. And when it finally did produce a Terraform course, the quiz answers sat right under the questions and every exercise came with the finished files.

Every course has a spending cap, $5 on Gemini and $10 on Claude by default, and we'll get to how it works in the bill section.

The first time, it asks for a Gemini API key and saves it, so you never set it up again.
