I prefer the long form:
“Disclaimer: the work was outsourced to a third party with a reputation for unreliable and poor quality results. These have been vetted but may still have irregularities that have not been identified. Use them at your own risk of loss or liability.”
We need a shorthand way of saying:
"An AI did the work, but I vouch for the result"
Saying "I did it" feels slightly sketchy, but saying "Claude did it" feels like avoiding responsibility
