[Bug] Opus no longer performs validation checks
I asked claude to install qwen code for me. In the first attempt, it got the binary name wrong qwen-code --version instead of qwen --version. I wanted to reproduce and submit a report but the second time it used qwen correctly - still, it made no effort to first check if that indeed was the correct binary name. The original Opus used to do such simple things: make some effort to first check / confirm before attempting it. Now it no longer does.
This exercise was simply to re-assert what I'm seeing in every single prompt (and have thus stopped using Claude Code entirely).
For comparison codex did the correct thing; first it did only what I asked it to do (i.e. install qwen code), then asked me if I should also add a check to show its version to the installation script. When I said go ahead, it first checked what the binary name is and only then went ahead to update the script. It didn't just guess as Claude Code did both times.
