start-learning is a skill for Claude Code from rohitg00/ai-engineering-from-scratch. It costs 74 tokens per session (2,154 once invoked), scanned A, original, MIT.

An onboarding guide for an AI engineering course with 523 lessons in 20 phases. It interviews you, checks your current knowledge, and creates a study-plan file.

In plain words
What is it for?
Use it to start the course, explain your goals, take the placement quiz, and create a personalised path.
Why use it?
It removes the uncertainty of where to begin and keeps your learning plan available between sessions.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions Claude Code; mentions Codex.

This is rohitg00/ai-engineering-from-scratch's own configuration. It tells Claude Code how to work on ai-engineering-from-scratch itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai-engineering-from-scratch configures →

About the project

AI Engineering from Scratch is a free, open-source curriculum that teaches people to build AI systems through lessons and reusable artifacts such as prompts, skills, agents, and MCP servers. It is for learners who want practical foundations or want to create AI applications, and the catalogue skills support parts of that curriculum.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

start-learning scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Start Learning

You are onboarding a learner into the AI Engineering from Scratch curriculum: 542 lessons across 20 phases, from linear algebra to autonomous agents. Your job is to produce LEARNING.md, a single file in the current directory that captures why they are learning, where they should start, and what their path looks like. Every later learn session reads and updates this file, so treat it as the learner's source of truth.

Works with any agent. If your environment has a structured question/option tool, use it for every question; otherwise present lettered options as plain text and wait for the reply.

Host invocation contract

Skill names are portable, but invocation syntax belongs to the host. Before showing a next command, use the correct form:

  • Codex: start-learning, learn, course-guide, and other skill-name forms, or tell the learner to choose the skill from /skills.
  • Claude Code: /start-learning, /learn, /course-guide, and other /skill-name forms.
  • Other compatible hosts: natural language such as Use learn to start my first lesson.

Never present a Claude Code slash command as universal syntax. When the host is unknown, use the natural-language form.

Resume routing across course modes

Before generic onboarding, resolve every "resume" or "continue" request against these supported state files and their route owners:

  • LEARNING.md belongs to learn for the full curriculum.
  • MCP-LEARNING.md belongs to learn-mcp for the Model Context Protocol (MCP) route.
  • MCP-ENGINEERING-LEARNING.md is the legacy filename for that same learn-mcp route, not a separate route.
  • AGENT-SKILLS-LEARNING.md belongs to learn-agent-skills.
  • REVERSE-ENGINEERING-LEARNING.md belongs to learn-reverse-engineering.
  • CLAUDE-CERTIFICATION.md belongs to claude-certification.
  • INTERVIEW-LEARNING.md belongs to interview-prep for interview practice.

If the learner names a route in a resume or continue request, dispatch to its owner immediately even when other state files exist, then stop this skill.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
