Follow-up: Tested my 9 thinking rules on long-horizon agent tasks (Terminal-Bench 2.0)

On my previous posts, people argued these thinking rules might work on short tests but would hurt long-horizon tasks.

Proof1 community thread

Key points

  • So I tested them on Terminal-Bench 2.0: same model (GLM-5.3-Flash), same agent, every task run with and without the rules.
  • I ran it on High thinking as Max thinking was taking so long that the model ran out of time for each task.
  • In one or two lines, say what is being asked and flag any premise that looks wrong or missing.
  • Do not hop between approaches because of a vague feeling.
