Discusses the safety of auto-execution mode versus manual approval in AI coding workflows. A cited study involving 1,053 paid testers showed that when a clearly dangerous command was swapped into a permission prompt, human testers caught it only 13.6% of the time (dropping to 5% after 50 prompts). In contrast, auto mode blocked the same commands 89% of the time, regardless of session length. The original author suggests that auto mode is actually more trustworthy than manual approval for preventing dangerous executions.
