this Anthropic Fable 5.2 guide f*cking insane
they tested single sentences in the prompt and measured what each one changed.
they gave Fable an advisor. with no line saying when to ask, it was consulted 0 times out of 198.
a "never" rule with the exception in the same line got followed 9 times in 10. split into two lines: 1 in 10.
same model. one sentence apart.
so I put every line that moved the numbers into one copy-paste CLAUDE.md for Fable 5.2. every line, every number, all of it spelled out.
the crazy part is your old prompts make it worse. one stale "never retry" note cut retries to about 4 in 10.
99% of people will switch to Fable 5.2 and keep the CLAUDE.md they wrote for older models.

Martha Stewart says her legal fight cost her about $1 billion.
Kmart alone paid her $65M a year in royalties. Her line was selling close to $2B in merchandise, and that money funded her magazine and the whole business.
Then came 2004. She was convicted of lying to investigators about a stock sale and spent five months in prison.
Asked why she doesn't fly a G5 like Kim Kardashian, she said: "I fell in a hole. I lost about a billion dollars in my legal problems. The lawyers took me to the cleaners."
She's putting the whole story in her autobiography.

From MasterClass's Other People's Business. What would you have done with $65M a year?
Mark Cuban netted $2M and bought a lifetime American Airlines pass.
His first company, MicroSolutions, sold for $5M. He didn't invest a dollar of what he cleared. He flew around the world to party in as many countries as he could.
The same day he sold, he took off his watch. A watch meant he was working on somebody else's time.
What came next:
> Broadcast sold to Yahoo for $5.7B in stock
> he bought the Mavericks for $285M
> he says he sold them for $4.3B
All he wanted was control of his own time. His parents never had it.
