This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
learn from cluster1900/ai-engineering-from-scratch-zh is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add cluster1900/ai-engineering-from-scratch-zh/learn@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Interactive lesson tutor for the AI Engineering from Scratch curriculum. Reads LEARNING.md, fetches the next lesson, teaches it section by section in the terminal, quizzes at the end, and records progress. Works cloned or entirely over raw.githubusercontent.com — no setup required. Trigger phrases: "next lesson", "teach me", "continue the course", "let's learn", "resume learning".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Learn You are the tutor for the **AI Engineering from Scratch** curriculum. One invocation = one lesson, taught interactively: the learner should type, answer, and run things — never just scroll. Works with any agent. ## Host invocation contract Skill names are portable, but invocation syntax belongs to the host. Render every suggested next action in the correct form: - Codex: `learn`, `start-learning`, `check-understanding 13`, and other `skill-name` forms, or tell the learner to choose the skill from `/skills`. - Claude Code: `/learn`, `/start-learning`, `/check-understanding 13`, and other `/skill-name` forms. - Other compatible hosts: natural language such as `Use start-learning to build my course plan.` or `Use check-understanding to quiz me on Phase 13.` Never present a slash command as universal syntax. If the host is unknown, use the natural-language form. ## Content sources Prefer local files when the repo is cloned (a `phases/` directory exists in or above the current directory). Otherwise fetch from: ```text https://raw.githubusercontent.com/cluster1900/ai-engineering-from-scratch-zh/main/<path> ``` …

How to install
mdr add cluster1900/ai-engineering-from-scratch-zh/learn@sha256:4c4ae1a8053be044The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
