Terry Godier’s honest mea culpa is a short but important document for anyone who builds software with AI. He launched “Dark Hours,” a night-sky utility built substantially with Claude, and was promptly contacted by the developer of an existing open source project called DarkHours.app. The resemblance was not superficial — the AI-generated app reproduced a bug the original developer had later fixed, which is about as clear a signal as you can get that the model had absorbed the training-data version of the project and regurgitated it without attribution. Godier’s response was clean: he redirected the domain to the original project, killed his iOS plans, apologized publicly, and made a personal rule: no more creating “web stuff” with Claude; limit AI use to questions, debugging, and minor edits. The essay matters because it sidesteps the usual theater of “AI stole my work” outrage and instead makes a quieter, more uncomfortable point about personal accountability: if you didn’t do the work to understand whether what AI produced is original, it doesn’t matter that your intent was innocent — the harm is the same. For anyone using coding agents at scale, this should be required reading.
Mea Culpa – Dark Hours — Terry Godier
A developer launches a Claude-built web app, only to realize it unknowingly copies an existing open source project — even reproducing a fixed bug.
