What makes this different
- Official docs as the source of truth: every feature / command / default behavior is verified against the Claude Code docs and Codex docs — no third-party guesses, no hearsay.
- Rewritten for beginners: each new concept follows a 3-part structure (scenario → real-life analogy → concrete use case); no command-line background required.
- Real, first-hand experience: plenty of first-person gotchas and judgment calls (with concrete details and real numbers), not vague "I think" filler.
- Runnable & self-verifiable: every hands-on step gives the full command + expected output for instant feedback.
- Original dark-engineering diagrams: 81 SVG/PNG diagrams, consistent dark style, ≤ 10 nodes each.

FAQ
| Q | A |
|---|---|
| Does it cost money? | The tutorial itself is completely free (MIT). But Claude Code / Codex themselves require a subscription or API payment — subscribe to whatever fits your needs. |
| Can I learn without command-line experience? | Yes. The first group, "Getting Started", is built for newcomers and starts from the basics. |
| Claude Code or Codex first? | The two are conceptually close, each with its strengths. Beginners: start with Codex — lower barrier and friendlier for users in mainland China; Claude Code has stricter account risk controls (higher ban risk), so it's safer to get comfortable first and switch later. The Codex section includes a "Migrating from Claude Code" comparison — the two are interchangeable. |
| Will it be updated? | Both tools iterate fast; important changes are tracked. See Commits for versions. |
