Well Claude doesn't do this, another model reading the session does. And the Astra misalignment classifier didn't detect this as misalignment.
The issue here is that Astra silently underperformed. The article makes it clear: a better option likely would have been an explicit refusal. I don't think OAI is suggesting Astra was doing something that it shouldn't be. It's arguably better for the tool to fail rather than needlessly burn tokens and make no progress for no obvious reason.
From OAI's perspective, this is a defect because it means they can't filter those rejections from their benchmark runs. The model just performs worse: not because it can't perform better, but because it's silently trying not to solve the problem.
