The AI Engineering Handbook

Cursor, Claude Code & Codex — The Craft of Shipping with AI

Read it once and the loop stops depending on which tool is open: you write the spec, let a failing test set the stop condition, and read the evidence at the gate instead of every diff.

Read it if you switch between tools. It shows Cursor, Claude Code and Codex side by side, stage by stage, from context to automation.

AI Engineering with Claude Code

A Practical Guide to Agentic Development in the Terminal

What it takes to leave a terminal agent running without you: a CLAUDE.md that names the gates, a permission mode for each kind of session, and hooks that enforce what a prompt only asks for.

Read it if you want to leave Claude Code running and still sign off on what it produces, with CI re-running the checks before anyone merges.

Agentic Engineering for Executives

The brief and the decisions you own: cost, business case, org design, roadmap and board reporting

Median of the ten: $47.99 The orange line sits at the median, between the fifth and sixth price. List prices, not promotions. A dash means the listing shows no page count. Six prices were read on the publisher’s own page and four on search listings. Left out: self-published Kindle titles priced under $20.

Median of ten list prices$47.99

Mean, for reference$45.29

Eight books, at a comparable ebook’s price$383.92

Quoted, rounded down$383

Eight books at $47.99 come to $383.92, quoted rounded down. Four of them are role paths, built from the library’s chapters in another order.

Why one price per title.

The comparable titles that list a page count run 110 to 376 pages. The four library titles run 600 to 1,523, and the four role paths 184 to 301. Pricing the library by the page would give a much higher number that is easy to challenge. One price per title is the cautious figure, and you can check every row of it.

Each path is a role track compiled into a book. Every step opens with why it comes now and closes with what shows you can move on. Each path starts with the scorecard for that role.

    The download panel lists every title: EPUB or PDF, English or Polish. There is no per-book charge.

  3. Keep what you downloaded.

    Your name and email are written into each file as a license page, in place of DRM that can break on your own e-reader. When your 12 months end, the books you downloaded stay yours. Please don’t re-share a file.

Checking your access

Questions about the books.

Something else? Write to support@developertoolkit.ai.

Do I pay per book?

No. The Toolkit opens all eight titles in EPUB and PDF, in English and Polish. There is no per-book charge.

What happens to my books after 12 months?

The books you downloaded are yours to keep. Downloading again, including a newer edition, needs active access, so download the editions you want while you have it.

Which book should I read first?

If you mostly use one tool, start with that tool’s book. If you switch between Claude Code, Codex and Cursor, the Handbook shows them side by side. If you lead a team, take the Tech Leads path. If you run engineering, take the CTOs path. If you fund it, take the Executives path.

Why read a book when the guides are online?

The books are built from the same pages you read on the site. This edition was built on 2026-10-03, so a guide changed since then can read differently online. A book gives you a fixed reading order and a file you can read offline on an e-reader. The role paths add a line at the start of every step on why it comes now, and one at the end on what shows you can move on.

EPUB or PDF?

EPUB suits Kindle and other e-readers. The PDF is the A4 edition that the page counts on this page describe. Both carry the same text.

Can I share a file with my team?

Please don’t. Each file carries your name and email on a license page. The Team Toolkit gives up to 10 people their own access, so each person downloads a copy of their own.

How did you price the books?

Against ten comparable ebooks, in the table above. We use the median list price, $47.99, for each of the eight books, which gives $383 after rounding down. The four role paths are built from the library’s chapters in another order. We count them because the Toolkit includes each as its own EPUB and PDF.
