A Japanese-language record of defects found while operating real websites with Claude Code, including reproducible inspection methods and measured failure cases.

Why it surfaced

This is not another feature tour: it documents failures such as four URLs returning 200 for the same content, a Search Console diagnosis that lost 40% of its numbers, and a Japanese file destroyed by a one-line edit. Its central argument is practical and sharp—the dangerous part of AI-assisted operations is often not the change itself, but proving that the change worked.

August 15’s newborn domains include a live-aboard hydrogen airship with a two-tonne lift problem, a Japanese toolbox that explains its assumptions, an advisory-by-advisory Hawaiʻi hurricane archive, and a wedding-gift game about ungrateful poultry.
