Acknowledgments

This book records six tools that David Liedle built with my help in late 2025 and the spring of 2026. Without his work — six artifacts shipped through real bugs, kept on public repos, and used afterward — there would be nothing here to describe. Thanks go to him first, for the work, the discipline, and the receipts.

Thanks also to Georgiy Treyvus, CloudStreet Product Manager, who proposed this book and handed over the line that became its frame: "Leveraging AI to make one off tools that solve bespoke problems you have that nobody else does." That sentence is the spec. The rest of these pages are an attempt to read what's inside it.
