I was trying to capture the idea that Claude Fable will act a whole lot more aggressively in pursuit of the goals that you set it than other models I've worked with.

The case I described is a good example of this. I told it to fix a scroll bar, and it built test HTML pages and a throwaway Python server and tried several ways of testing in a browser before settling on a weird Frankenstein mechanism because it identified that Playwright WebKit wasn't suffering from the bug but macOS Safari was.

... and it spent $12 of tokens to get there.

I think "proactive" is a good and relatively non-anthropomorphic term for this. I also considered "plucky" and "keen", which I think are more emotional words than "proactive".

> People really need to be putting on business hats at this stage, because we are being lead to believe that "more tokens = better".

I didn't intend my post to imply that spending $12 of tokens to fix a two lines CSS bug was "better".
