I think you should avoid reading the thinking blocks unless you spot errors in the output.

I am very confident the reason we get all these second guessing and "but wait" and "actually" is they train them on collapsed corrected sessions. i.e they take sessions that look like this:

  user: Do x.
  agent: the user wants me to do x. I think I need to do a and b first.
  agent: does a.
  agent: does b.
  user: No no no doing a was wrong you should do c before b.
  agent: undoes a. does c.
  agent: does x

And they turn it to a session where the user correction shows up in the thinking. i.e

  user: do x.
  agent: the user wants me to do x. I think I need to do a and b first.
  agent: but wait maybe I should do c instead of a
  agent: does c
  agent: does b
  agent: does x
