I hate NOTHING quite the way how Claude jovially and endlessly raves about the 9/10 tasks it "succeeded" at after making them up, while conveniently forgetting to mention it completely and utterly failed at the main task I asked it to do.
That reminds me of the West Wing scene s2e12 "The Drop In" between Leo McGarry (White House Chief of Staff) and President Bartlet discussing a missile defense test:
LEO
[hands him some papers] I really think you should know...
BARTLET
Yes?
LEO
That nine out of ten criterion that the DOD lays down for success in these
tests were met.
BARTLET
The tenth being?
LEO
They missed the target.
BARTLET
[with sarcasm] Damn!
LEO
Sir!
BARTLET
So close.
LEO
Mr. President.
BARTLET
That tenth one! See, if there were just nine...
