gpt-5 command line use is bizarre. It always writes extraordinarily complicated pipelines that Claude instead just writes simple commands for.

My use case does better with the latter because frequently the agent fails to do things and then can't look back at intermediate.

E.g. Command | Complicated Grep | Complicated Sed

Is way worse than multistep

Command > tmpfile

And then grep etc. Because latter can reuse tmpfile if grep is wrong.
