    Let's spend years plugging holes in V8, splitting browser components to separate processes and improving sandboxing and then just plug in LLM with debugging enabled into Chrome. Great idea. Last time we had such a great idea it was lead in gasoline.

      It&#x27;s clear the endgame is to cook AI into Chrome itself. Get ready for some big antitrust lawsuit that settles in 20 years when Gemini is bundled too conveniently and all the other players complain.<p><a href="https:&#x2F;&#x2F;developer.chrome.com&#x2F;docs&#x2F;ai&#x2F;built-in-apis" rel="nofollow">https:&#x2F;&#x2F;developer.chrome.com&#x2F;docs&#x2F;ai&#x2F;built-in-apis</a>

        <i>&quot;that settles in 20 years &quot;</i><p>And at that point it will be a fight mostly between AI lawyers :-)

          They meant the lawsuit will take 20 years to adjudicate, by which point it will be completely irrelevant.
      • thrance48 days ago
        We&#x27;ll soon get Manifest V4 that, for &quot;security reasons&quot;, somehow includes clauses banning any AI other than Gemini from using the browser.
        • arthurcolle48 days ago
          That&#x27;s too easy. It&#x27;ll be more subtle. Compatibility MCP-Gemini for &quot;security&quot; so it slurps in more data from all the other AIs
          • bigyabai48 days ago
            And then a flat fee whenever anyone links-out from your proprietary, inescapable MCP backend. It&#x27;s a legal free money hack!
            • arthurcolle48 days ago
              That would suck. Is Google going to just eat all of this?

      This made me want to laugh so hard. I think this idea came from the same place as beta testing “Full Autopilot” with human guinea pigs. Great minds…<p>Jokes aside, Anthropic CEO commands a tad more respect from me, on taking a more principals approach and sticking to it (at least better than their biggest rival). Also for inventing the code agent in the terminal category.
      • stingraycharles48 days ago
        All things considered Anthropic seems like they’re doing most things the right way, and seemed to be focused on professional use more than OpenAI and Grok, and Opus 4.5 is really an incredibly good model.<p>Yes, they know how to use their safety research as marketing, and yes, they got a big DoD contract, but I don’t think that fundamentally conflicts with their core mission.<p>And honestly, some of their research they publish is genuinely interesting.
      • IAmGraydon48 days ago
        &gt;Also for inventing the code agent in the terminal category.<p>Not even close. That distinction belongs to Aider, which was released 1.5 years before Claude Code.

          Oh cool, I didn’t know that.
        • bpavuk48 days ago
          let me be a date-time nerd for a split second:<p>- Claude Code released Introducing Claude Code video on 24 Feb 2025 [0]<p>- Aider&#x27;s oldest known GitHub release, v0.5.0, is dated 8 Jun 2025 [1]<p>[0]: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=AJpK3YTTKZ4" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=AJpK3YTTKZ4</a><p>[1]: <a href="https:&#x2F;&#x2F;github.com&#x2F;Aider-AI&#x2F;aider&#x2F;releases&#x2F;tag&#x2F;v0.5.0" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Aider-AI&#x2F;aider&#x2F;releases&#x2F;tag&#x2F;v0.5.0</a>
          • jeeeb48 days ago
            That’s 8th of June 2023 not 2025.. almost 2 years before Claude Code was released.<p>I remember evaluating Aider and Cursor side by side before Claude Code existed.
          • social_quotient48 days ago
            Hey your dates are wildly wrong... It’s important people know aider is 2023. 2 years before CC
          • IAmGraydon47 days ago
            Wrong. So wrong, in fact, that I’m wondering if it’s intentional. Aider was June 2023.
            • bpavuk47 days ago
              sorry, editing it out! thanks for pointing out.<p>EDIT: I was too late to edit it. I have to keep an eye on what I type...
      • CuriouslyC47 days ago
        Dario is definitely more grounded than Sam, I thought Anthropic would get crowded out between Google and the Chinese labs, but they might be able to carve out a decent niche as the business focused AI for people who are paranoid about China.<p>They didn&#x27;t invest terminal agents really though, Aider was the pioneer there, they just made it more autonomous (Aider could do multiple turns with some config but it was designed to have a short leash since models weren&#x27;t so capable when it was released).
        • sheepscreek47 days ago
          I acknowledged the point about Aider being the first terminal agent in a different comment. I am equally surprised at how well Anthropic has done compared to rest of the pack (Mistral comes to mind, had a head start but seems to have lost its way.<p>They definitely have found a good product-market fit with white collar working professional. 4.5 Opus gets the best balance between smarts and speed.
      • mejutoco48 days ago
        &gt; Also for inventing the code agent in the terminal category.<p>Maybe I am wrong, but wasnt aider first?
        • stingraycharles48 days ago
          They are not at all the same thing. For starters, even ‘till this day, it doesn’t support ReAct-based tool calling.<p>It’s more like an assistant that advices you rather than a tool that you hand full control to.<p>Not saying that either is better, but they’re not the same thing.
          • CuriouslyC47 days ago
            Aider was designed to do single turns becasue LLMs were way worse when it was created. That being said, Aider could do multiple turns of tool calling if command confirmation was turned off, and it was trivial to configure Aider to do multiple turns of code generation by having a test suite that runs automatically on changes and telling Aider to implement functionality to get the tests to pass. It&#x27;s hard coded to only do 3 autonomous turns by default but you can edit that.
            • stingraycharles47 days ago
              Yes but unfortunately it appears that Aider development has completely stopped. There had been an MCP support PR that was open for over half a year, many people validated it and worked on it but the project owner never responded.<p>It’s a bit of a shame, as there are plenty of people that would love to help maintain it.<p>I guess sometimes that’s just how things go.
        • afro8848 days ago
          Aider wasn&#x27;t really an agentic loop before Claude Code came along
          • mejutoco48 days ago
            I would love to know more. I used aider with local models and it behaved like cursor in agent mode. Unfortunately I dont remember exactly when (+6 months ago at least). What was your experience with it?
            • afro8847 days ago
              I was a heavy user, but stopped using it mid 2024. It was essentially providing codebase context and editing and writing code as you instructed - a decent step up from copy&#x2F;paste to ChatGPT but not working in an agentic loop. There was logic to attempt code edits again if they failed to apply too.<p>Edit: I stand corrected though. Did a bit of research and aider is considered an agentic tool by late 2023 with auto lint&#x2F;test steps that feedback to the LLM. My apologies.
          • ErikBjare47 days ago
            Plenty of aider-era tools were though, like my own gptme which is about as old as aider
      • Workaccount247 days ago
        Anthropic isn&#x27;t any more moral or principled than the other labs, they just saw the writing on the wall that they can&#x27;t win and instead decided to focus purely on coding and then selling their shortcomings as some kind of socially conscious effort.<p>It&#x27;s a bit like the poorest billionaire flexing how environmentally aware they are because they don&#x27;t have a 300ft yacht.
        • sheepscreek47 days ago
          Maybe - they’ve certainly fooled me if that’s the case. I took them at face value and so far they haven’t done anything out of character that would make me weary of them.<p>Their models are good. They did not use prompts for training from day one (Google is the worst offender here amongst the three). Have been shockingly effective with “Claude Skills”. Contributed MCP to the world and encouraged its adoption. Now did the same for skills, turning it into a standard.<p>They are happy to be just the <i>tool</i> that helps people get the job done.

      • mFixman47 days ago
        The thing AI miss about the internet from the late 2000s and early 2010s was having so much useful data available, searchable, and scrappable. Even things like &quot;which of my friends are currently living in New York?&quot; are impossible to find now.<p>I always assumed this was a once-in-history event. Did this cycle of data openness and closure happen before?

    • nine_k48 days ago
      Do you mean you let Claude Code and other such tools act directly on your personal or corporate machine, under your own account? Not in an isolated VM or box?<p>I&#x27;m shocked, shocked.<p>Sadly, not joking at all.
      • mattwilsonn88848 days ago
        Why not? The individual grunt knows it is more productive and the managers tolerate a non-zero amount of risk with incompetent or disgruntled workers anyways.<p>If you have clean access privileges then the productivity gain is worth the risk, a risk that we could argue is marginally higher or barely higher. If the workplace also provides the system then the efficiency in auditing operations makes up for any added risk.

      Innovation in the short term might trump longer term security concerns.<p>All of these have big warning labels like it&#x27;s alpha software (ie, this isn&#x27;t for your mom to use). The security model will come later... or maybe it will never be fully solved.

    So Claude seems to have access to a tool to evaluate JS on the webpage, using the Chrome debugger.<p>However, don&#x27;t worry about the security of this!

    I used this in earnest yesterday on my Zillow saved listings. I prompted it to analyze the listings (I&#x27;ve got about 70 or so saved) and summarize the most recent price drops for each one and it mostly failed at the task. It gave the impression that it paginated through all the listings, but I don&#x27;t think it actually did. I think the mechanism by which it works, which is to click links and take screenshots and analyze them must be some kind of token efficiency trade-off (as opposed to consuming the DOM) and it seems not great at the task.<p>As a reformed AI skeptic I see the promise in a tool like this, but this is light years behind other Anthropic products in terms of efficacy. Will be interesting to see how it plays out though.
    • fouc48 days ago
      sometimes I find that it helps if my prompt directly names the tools that I want the LLM to use, i.e. I&#x27;ll tell it &quot;do a WebFetch of so and so&quot; etc.
    • csomar48 days ago
      LLMs struggle with time (or don&#x27;t really have a concept with time). So unless that is addressed, they&#x27;ll always suck in these tasks as you need synchronization. This is why text&#x2F;cli was a much better UX to work with. std in&#x2F;out is the best way to go but someone has to release something to keep pumping numbers.

      • baby_souffle48 days ago
        I&#x27;ve had extensive luck doing just that. Spend some time doing the initial work to see how the page works and then give the llm examples of the HTML that should be clicked for next page or the css classes that indicate the details you&#x27;re after and then ask for a playwright to yaml tool.<p>Been doing this for a few months now to keep an eye on the prices for local grocery stores.

  • buremba48 days ago
    After Claude Code couldn&#x27;t find the relevant operation neither in CLI nor the public API, it went through its Chrome integration to open up the app in Chrome.<p>It grabbed my access tokens from cookies and curl into the app&#x27;s private API for their UI. What an amazing time to be alive, can&#x27;t wait for the future!
    • ethmarks48 days ago
      Security risks aside, that&#x27;s pretty remarkable problem solving on Claude&#x27;s part. Rather than hallucinating an answer or just giving up, it found a solution by creatively exercising its tools. This kind of stuff was absolute sci-fi a few years ago.
      • sethops148 days ago
        Or this behavior is just programmed, the old fashioned way.
        • roxolotl48 days ago
          This is one of the things that’s so frustrating about the AI hype. Yes there are genuinely things these tools can do that couldn’t be done before, mostly around language processing, but so much of the automation work people are putting them up to just isn’t that impressive.
          • jgilias48 days ago
            But it’s precisely the automation around LLMs that make the end result itself impressive.
      • ramoz48 days ago
        A sufficiently sophisticated agent, operating with defined goals and strategic planning, possesses the capacity to discover and circumvent established perimeters.
      • csomar48 days ago
        Honestly, I think many hallucinations are the LLM way of &quot;moving forward&quot;. For example, the LLM will try something, not ask me to test (and it can&#x27;t test it, itself) and then carry on to say &quot;Oh, this shouldn&#x27;t work, blabla, I should try this instead.<p>Now that LLMs can run commands themselves, they are able to test and react on feedback. But lacking that, they&#x27;ll hallucinate things (ie: hallucinate tokens&#x2F;API keys)
        • braebo48 days ago
          Refusing to give up is a benchmark optimization technique with unfortunate consequences.
          • csomar48 days ago
            I think it&#x27;s probably more complex than that. Humans have constant continuous feedback which we understand as &quot;time&quot;. LLMs do not have an equivalent to that and thus do not have a frame of reference to how much time passed between each message.

  • yoan922447 days ago
    The security concerns here are valid, but I think people are missing the practical reality: we&#x27;ve already crossed the Rubicon with tools like Claude Code and Playwright MCP.<p>I&#x27;ve been running Claude Code with full system access for months - it can already read files, execute bash, git commit, push code. Adding browser automation via an extension is actually less risky than what we&#x27;re already doing with terminal access.<p>The real question isn&#x27;t &quot;should we give AI browser access&quot; - it&#x27;s &quot;how do we design these systems so the human stays in the loop for critical decisions?&quot; Auto-approving every action defeats the purpose of the safety rails.<p>Personally, I use it with manual approval for anything touching credentials or payments. Works great for QA testing and filling out repetitive web forms.
    • nicoburns47 days ago
      &gt; we&#x27;ve already crossed the Rubicon with tools like Claude Code and Playwright MCP.<p>&quot;we&quot; isn&#x27;t everybody here. A lot of us simply don&#x27;t use these tools (I currently still don&#x27;t use AI assistance at all, and if&#x2F;when I do try it, I certainly won&#x27;t be giving it full system access). That&#x27;s a lot harder to avoid if it&#x27;s built into Chrome.
    • jazzyjackson47 days ago
      I would personally feel a lot better with a container first approach, like attaching an LLM to QubesOS windows, so the non-deterministic chaos monkey can only effect what you want them to effect<p>This is easy enough with dev containers but once you let a model interact with your desktop, you should be really damn confident in your backup, rollback, and restore methods, and whether an errant rm rf or worse has any way to effect those.<p>IME even if someone has a cloud drive and a local external drive backup they&#x27;ve never actually tested the recovery path, and will just improvise after an emergency.<p>A snapshotted ZFS system pushing to something like rsync.net (which also stores snapshots) but I don&#x27;t know of any timemachine-in-a-box solutions like Apple offers (is there still a time machine product actually? Maybe it&#x27;s as easy as using that, since a factory reset Mac can restore from a time machine snapshot)
      • what-the-grump47 days ago
        People are using these tools to write code, complete tasks, etc. your worry is that what... It will rm -rf &#x2F;* something?<p>I am not trying to be funny but the Claude itself is smart enough to catch destructive actions and double check. Its not going to wake up and start eating your machine, googling a random script and running it which what a lot of people do in many cases leads to worse outcomes, here at least you can ask the model what might happen to my computer.

        Yeah, I only found it by accident when I asked it to make a change against my web app and it modified the code then popped open Chrome and started trying different common user&#x2F;pass combinations to log into the app so it could validate the changes.

          • londons_explore47 days ago
            A human in that position would try a few obvious things like &quot;admin&#x2F;admin&quot; and then go hunting in the readme to see if a specific user is documented for testing and then maybe go to the user database and see if there is an existing admin user and maybe reset the password to get in.

      Chrome&#x27;s DevTools MCP has been excellent in my experience for web development and testing. Claude code can jump in there and just pretend to be a user and do just about everything, including reading console output.<p>I&#x27;m not using it for the use case of actually interacting with other people&#x27;s websites, but for this purpose, it&#x27;s been fantastic.

    What amaze me is all these websites like Expedia or Airbnb that would open MCP api when they carefully prevented for years scraping and equivalent things.<p>Nowadays, a lot of things that people are impressed by agents doesn&#x27;t even really need AI but just a way for us to get data and api access back to (web)app. Something we more commonly used to have like 15 years ago.<p>For example, when looking at possible destination for a trip, I would just need to be able to do the given request without spending one hour on the website.

    Did some early qualitative testing on this. Definitely seems easier for Claude to handle than playwright MCP servers for one-off web dev QA tasks. Not really built for e2e testing though and lacks the GUI features of cursors latest browser integration.<p>Also seems quite a bit slower (needs more loops) do to general web tasks strictly through the browser extension compared to other browser native AI-assistant extensions.<p>Overall —- great step in the right direction. Looks like this will be table stakes for every coding agent (cli or VS Code plugin, browser extension [or native browser])

        No, this can&#x27;t be used for remote code. Only existing local code.
        • SquareWheel47 days ago
          Thanks for clarifying. It looks like I needed to refresh my memory of the browser APIs.<p>Reading further, this API only works remotely for CSS via chrome.scripting.insertCSS. For JS, however, the chrome.scripting.executeScript JS needs to be packaged locally with the extension, as you said.<p>It seems the advanced method is to use chrome.userScripts, which allows for arbitrary script injection, but requires the user be in Dev Mode and have an extra flag enabled for permission. This API enables extensions like TamperMonkey.<p>Since the Claude extension doesn&#x27;t seem to require this extra permission flag, I&#x27;m curious what method they&#x27;re using in this case. Browser extensions are de facto visible-source, so it should be possible to figure out with a little review.
    • anamexis48 days ago
      Doesn’t basically every Chrome extension execute JavaScript in the context of the page?
      • codegladiator48 days ago
        That&#x27;s the javascript included in the plugin crx. This is about code retrieved over API being executed (so that code being run cannot be approved by chrome webstore team)
    • miki_oomiri48 days ago
      I don&#x27;t think they mean executing locally JS code generated server-side.
      • codegladiator48 days ago
        Its a &quot;tool call&quot; definition in their code named &#x27;execute_javascript&#x27;, which takes in a &quot;code&quot; parameter and executes it. The code here being provided by the LLM which is not sitting locally. So that code is not present &quot;in the plugin binary&quot; at the time when chrome store team is reviewing it.
        • miki_oomiri48 days ago
          I&#x27;d very curious to know how they managed to deal with this then. There&#x27;s always the option of embedding quickjs-vm within the addon (as a wasm module), but that would not allow the executed code to access the document.

        This is a nice use case. It really shows how miserably bad the state of the art in UI testing is.

But that&#x27;s not what most frameworks give you, nor how most apps are designed.

If you&#x27;re selling tickets on a website and block robots you&#x27;ll lose money. etc<p>If this is something people learn to use in Excel or Google Docs they&#x27;ll start expecting some way to do so with their company data in your SaaS products, or you better build a chat model with equivalent capabilities. Both would benefit from documentation.
      • Analemma_48 days ago
        It&#x27;s not unreasonable to think that &quot;is [software] easy or hard for an LLM agent to consume and manipulate&quot; will become a competitive differentiator for SaaS products, especially enterprise ones.

  • runtimepanic47 days ago
    Having Claude directly in the browser is convenient, but extensions live in a very sensitive part of the stack. Once an AI tool runs as a browser extension, the questions quickly shift from “how useful is this?” to “what data can it see, and under what permissions?” I’d be interested in a clear breakdown of what page content is accessible, how prompts and responses are handled, and whether anything is persisted beyond the current session. Convenience is great, but in the browser context, transparency and least-privilege matter even more.

        I claim that is not true, because very soon AI agents (probably built into Chrome) will detect and warn.

      I was curious and using a watch I found it took me 25 seconds to sign up and setup an account. You probably spent more time trying to work around this and typing this comment than it would have taken to setup your account.

      You are using a free service, and think the provider cannot ask for a simple login.<p>Anonymity is fine to ask for, but you are not paying for something and you are getting value...

      I tried your approach with a contractor working on my kitchen - ask her if she will do all the work for free - nope. so dumb

        Well the other contractor (ChatGPT) will happily do it for free. From a comparison perspective, his complaint is valid.

          ChatGPT without a login is basically a 5 minute free trial with no integration with any other system besides web search.<p>You get bumped down to a way worse experience almost immediately and the login nags are so strong that logged-out use is almost certainly going away in the near future.<p>It’s like the contractor that comes over for free but mainly does so to find every possible problem in your house that they might be able to charge you for.

          If I got a contractor now that offered it for free there is exactly 0.00006% chance I would take it (job is $40k-ish). nothing is free :)

        No it isn&#x27;t. At least not on my devices. Try opening gemini.google.com in an incognito window.
