[Bug] Claude 4.7 Opus degraded reasoning in issue triage tasks

Bug Description
I feel like opus 4.7 these days is really struggling. What normal would kick off as its own investigation, when I asked it to triage a GitHub issue, turned into a first response of the model parroting back the issue directly to me. I then had to hand hold it, all the way until the end result which in previous weeks, would have happened without me having to direct the model so much. This doesn't feel like normal behavior (I use CC + Opus 4.7 every single day).
