>That the server can send you a backdoor every single time, made just for you, and nobody else will ever know? There is no "backdoor" when the browser is sandboxed. "backdoor" is a specific thing, I think you need to read up on it before you keep using it incorrectly: https://en.wikipedia.org/wiki/Backdoor_(computing) >On the other hand, an app is sandboxed, too (on mobile OSes like Android and iOS). When you download it, you can check a hash that you can (if you want to) compare with a friend to see if they got the same app. That isn't what "sandboxed" means, it has nothing to do with checking hashes. And no, mobile apps are not really sandboxed, they have full access to your mobile device once you install it and give it access - and let's be real, most people are just going to blindly click "allow" for anything the app requests after installing an app. >With an app, there is intermediary (the "app store") that would need to collude with the developers to send a backdoor just for you, and even then you would still have the app binary as proof. You keep referring to "backdoor", and I don't think you really know what that means. >That's always a question I have with "secure" web services: if you use ProtonMail, you trust that Proton doesn't send you a web page that leaks your key. But if you trust Proton for that, what's the point of the end-to-end encryption? When you use the Signal app, the whole idea is that you don't have to trust Signal for the end-to-end encryption, at all. That isn't how any of this works. The main value proposition of Signal is that we do trust its end-to-end encryption. Protonmail sending a "web page" that "leaks your key"? WTF?
Hey all, Boris from the Claude Code team here. I just responded on the issue, and cross-posting here for input. --- Hi, thanks for the detailed analysis. Before I keep going, I wanted to say I appreciate the depth of thinking & care that went into this. There's a lot here, I will try to break it down a bit. These are the two core things happening: > `redact-thinking-2026-02-12` This beta header hides thinking from the UI, since most people don't look at it. It *does not* impact thinking itself, nor does it impact thinking budgets or the way extended reasoning works under the hood. It is a UI-only change. Under the hood, by setting this header we avoid needing thinking summaries, which reduces latency. You can opt out of it with `showThinkingSummaries: true` in your settings.json (see [docs]( https://code.claude.com/docs/en/settings#available-settings )). If you are analyzing locally stored transcripts, you wouldn't see raw thinking stored when this header is set, which is likely influencing the analysis. When Claude sees lack of thinking in transcripts for this analysis, it may not realize that the thinking is still there, and is simply not user-facing. > Thinking depth had already dropped ~67% by late February We landed two changes in Feb that would have impacted this. We evaluated both carefully: 1/ Opus 4.6 launch → adaptive thinking default (Feb 9) Opus 4.6 supports adaptive thinking, which is different from thinking budgets that we used to support. In this mode, the model decides how long to think for, which tends to work better than fixed thinking budgets across the board. `CLAUDE_CODE_DISABLE_ADAPTIVE_THINKING` to opt out. 2/ Medium effort (85) default on Opus 4.6 (Mar 3) We found that effort=85 was a sweet spot on the intelligence-latency/cost curve for most users, improving token efficiency while reducing latency. On of our product principles is to avoid changing settings on users' behalf, and ideally we would have set effort=85 from the start. We felt this was an important setting to change, so our approach was to: 1. Roll it out with a dialog so users are aware of the change and have a chance to opt out 2. Show the effort the first few times you opened Claude Code, so it wasn't surprising. Some people want the model to think for longer, even if it takes more time and tokens. To improve intelligence more, set effort=high via `/effort` or in your settings.json. This setting is sticky across sessions, and can be shared among users. You can also use the ULTRATHINK keyword to use high effort for a single turn, or set `/effort max` to use even higher effort for the rest of the conversation. Going forward, we will test defaulting Teams and Enterprise users to high effort, to benefit from extended thinking even if it comes at the cost of additional tokens & latency. This default is configurable in exactly the same way, via `/effort` and settings.json.
