Hi everyone, Thariq from the Claude Code team here.

Thanks for reporting this. We fixed a Claude Code harness issue that was introduced on 1/26. This was rolled back on 1/28 as soon as we found it.

Run `claude update` to make sure you're on the latest version.

Is there compensation for the tokens because Claude wasted all of them?

Anywhere we can read more about what a "harness issue" means? What was the impact of it?

It happened before 1/26. I noticed when it started modifying plans significantly with "improvements".

For the models themselves, less so for the scaffolding, considering things like the long running TPU bug that happened, are there not internal quality measures looking at samples of real outputs? Using the real systems on benchmarks and looking for degraded perf or things like skipping refusals? Aside from degrading stuff for users, with the focus on AI safety wouldn't that be important to have in case an inference bug messes with something that affects the post training and it starts giving out dangerous bioweapon construction info or the other things that are guarded against and talked about in the model cards?

Hi. Do you guys have internal degradation tests?
