Can we actually build the thing now?

Описание и применение

Система обучения, использующая реальные модели Gemini и Claude, генерирует актуальные курсы с тестами и отслеживанием расходов.

Задача

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

Результат

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

Рабочий процесс

• 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

Доказательства

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

Источник

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.

Источник

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.

Источник

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