Xcode 26.4: Regressions in Intelligence features

Just installed the new Xcode 26.4 RC build (17E192) after happily using 26.3 for a few months. I'm noticing some immediate regressions in the Intelligence features:

Frequent losing of OAuth token (Claude Agent). This had previously been fixed and now is back.
Agent "Thinking" is constrained to thought bubble windows, which are (a) too small to read, (b) not scrollable when thinking goes beyond a few paragraphs. Yes they are tappable when thinking is finished, but this doesn't help.
Due to (2), in deep thinking, it's impossible to follow progress beyond the visible window, so impossible to know if the agent is going off the rails.
I'm noticing just more general slowness to complete tasks. Not just complete them -- it seems like it takes longer to START tasks, which is really weird. It sits there thinking for longer. Same project, same model as before.
Every time you tap "New Chat" it presents both Claude and Codex choices, even if you're only signed into one. This turned a simple single tap into now a required two taps.

Overall this feels like a frustrating setback after a very positive user experience in 26.3.

One more issue: I'm seeing Claude Agent just randomly stop in the middle of working. After submitting a prompt, it will occasionally respond with "Let me start by understanding the current (whatever) implementation." And then do nothing. This is different than the OAuth issue, as the OAuth token is still valid in this case.

Yes I must admit the same issues. I have claude and anthropic signed in. I want to select a model and then just use that every time I click new message. I don't like the mental burden of having to select the working model every time I click a new message. I have the other issues listed as well, sometimes it just stalls and I need to send another message to get it going again.

First, thank you for taking the time to post these. We really love hearing from our developers because this helps us make the tools better.

Re: OAuth — hmm, OK we're investigating. Is there any pattern to this? Do you see this after a certain amount of time?

Re: Thinking — interesting, this is good feedback about how you're using thinking as progress tracking. We know about the issue where you can't open the popover until the thinking is done. But, sounds like you really want a "don't put thinking in a bubble" entirely because that's part of your tracking of the agent progress. Makes sense. It'd be great if you could file a feedback request specifically for this.

Re: Slowness to start — yeah, I agree that sounds weird. The only way we have to debug this at the moment is if you attach the contents of your conversation via the "Bug" button at the bottom of the transcript.

Re: Codex & Claude showing — Have you downloaded both agents using the Intelligence settings even if you haven't logged in? We support talking to the agent once you've downloaded without logging in since some enterprise configurations automatically handle authentication without logging in via Xcode.

Thanks for the detailed response! To answer your questions:

OAuth - I don't see a pattern other than time. It seems to lose the OAuth token 2 or 3 times per day. It also doesn't seem to depend on idle time. I can be in the middle of working and it will lose the token.
Yes, especially since thinking can go off the rails or go into a nearly-endless loop, this serves as a way to monitor and guide agent progress. I did file a feedback on all the issues, btw! (FB22310171 on the whole set of issues, and I also just filed FB22316631 per your request on this specific one.)
Next time this occurs, I will attach it to the Feedback report.
No, I have never downloaded or setup Codex.
I especially want to highlight the additional bug I reported in my Feedback report but did not post here -- the agent will take action even if I specifically tell it to ask for approval before proceding. This is concerning because there is now some internal state where the agent believes it has gotten permission even though it hasn't. (It literally says this in its thinking bubble.)

Thanks!
