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 Cursor

A Practical Guide to AI-Native Development in the Cursor IDE

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.

Role path 1 of 3

Agentic Engineering for Developers

A reading path up the autonomy ladder: from your first merged agent change to reviewing evidence instead of diffs

Write the instructions file, set permissions, give the agent a feedback loop it runs itself, then approve changes on their evidence instead of reading every line.

Read it if you already use an agent and want a path from your first merged change to reviewing evidence.

The first three steps

Agentic Engineering for CTOs and Executives

The brief, the decisions you own and the operating model for agent-built software

The dated evidence, the cost of an accepted change, a pilot with a control group, autonomy by risk class, agent security, spend and the board update.

Read it if you are a CTO, a VP of engineering or an executive who funds them. The executive brief comes first, then the CTO steps it does not already cover.

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

Seven books, at a comparable ebook’s price$335.93

Quoted, rounded down$335

Seven books at $47.99 come to $335.93, quoted rounded down. Three 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 481 to 1,224, and the three role paths 199 to 304. 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.

Checking your plan

Questions about the books.

Something else? Write to support@developertoolkit.ai.

Do I pay per book?

No. Every paid plan opens all seven titles in EPUB and PDF, in English and Polish. There is no per-book charge.

What happens to my books if I cancel?

Access runs to the end of the period you paid for. Books you downloaded are yours to keep.

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 answer to a board, take the CTOs and 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. Team includes everything in Solo Developer for everyone on your team, 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 seven books, which gives $335 after rounding down. The three role paths are built from the library’s chapters in another order. We count them because every plan includes each as its own EPUB and PDF.
