Happy to have my mind changed, yet I am not 100% convinced closing the issue as completed captures the feedback.

From the contents of the issue, this seems like a fairly clear default effort issue. Would love your input if there's something specific that you think is unaddressed.

I commented on the GH issue, but Ive had effort set to 'high' for however long its been available and had a marked decline since... checks notes... about 23 March according to slack messages I sent to the team to see if I was alone (I wasnt).
EDIT: actually the first glaring issue I remember was on 20 March where it hallucinated a full sha from a short sha while updating my github actions version pinning. That follows a pattern of it making really egregious assumptions about things without first validating or checking. Ive also had it answer with hallucinated information instead of looking online first (to a higher degree than Ive been used to after using these models daily for the past ~6 months)

It hallucinated a GUID for me instead of using the one in the RFC for webscokets. Fun part was that the beginning was the same. Then it hardcoded the unit tests to be green with the wrong GUID.

The hallucinated GUIDs are a class of failure that prompt instructions will never reliably prevent. The fix that worked: regex patterns running on every file the agent produces, before anything executes.

Well Ive never had the issue before and have hit that / similar issues every few days over the past couple weeks.

From this reply, it seems that it has nothing to do with `/effort`: https://github.com/anthropics/claude-code/issues/42796#issue...
I hope you take this seriously. I'm considering moving my company off of Claude Code immediately.
Closing the GH issue without first engaging with the OP is just a slap in the face, especially given how much hard work they've done on your behalf.

The OP “bug report” is a wall of AI slop generated from looking at its own chat transcripts

Do you disagree with any of the data or conclusions?

I must admit, the fact that the writing was well formatted and structured was an instant turn off. I did find it insightful. I would have been more willing to read it if it was one lower case run on line with typos one would expect from a prepubescent child. I am both joking and being serious at the same time. What a world.

It's only slop if it's wrong or irrelevant.

Gotcha. It seemed though from the replies on the github ticket that at least some of the problem was unrelated to effort settings.
