So you're telling me we spent over a decade turning the browser from a sieve full of vulnerabilities into an impenetrable sandbox, and now we're directly introducing an APT?

Gah - What a dumb take. There's nothing APT about an agent that you can open on a webpage to do things. If anything it's a fantastic accessibility win. Some people's critical thinking turns off when it comes to AI flows.

Fine. Now give me back browser plugins that can actually do whatever I want them to.

You can justify manifest v3 for security reasons, or you can can do this. You cannot do both without severe cognitive dissonance.


> You cannot do both without severe cognitive dissonance

Like that stopped anyone before from just ignoring the "cognitive dissonance" and moving ahead anyways with whatever gives shareholders the most short-term profits...


> There's nothing APT about an agent that you can open on a webpage to do things

You can "hack" the agent by literally just putting some text on any website it reads. AI browsers have turned EVERY comment feature EVERYWHERE into XSS.

This is stupid but mostly benign where the AI only spits out text. It's catastrophic if the AI does anything to the webpage. (And AI firms want people to use this everywhere)

What is the future of this product supposed to be? I send a 1 dollar cent transaction to someone, with a prompt injection in the description, and their AI agent gleefully sends me a thousand bucks in return?

1) This is not APT.

2) While injection has potential, this is fairly well mitigated. Look at comet and others.

These are all whataboutisms coming from a place of fear.


Pretty sure simonw's lethal trifecta [1] has not been "fairly well" mitigated.

Good thing we're not talking about a LLM then.

From the article: It's a side page agent that has only access to the page, and outputs content in text only, and awaits user confirmation on actions. It's all on the page. It's I guess it's a mono-fecta?


Then it's contained but depending on the user it can be a vector for a (para)-social engineering attack.

PS: It is Gemini based, that's an LLM.


No LLM model has enough mitigations to prevent injections.

Today I also discovered that the speed of gpt-5.3-codex in Codex CLI is extremely slow, and then I found that response.model was routed back to gpt-5.2-2025-12-11 by the upstream.


Update: I can access gpt-5.3-codex now. According to Alexander Embiricos, 9% of users were affected by over flagging over a period of 3 hours.


Please use the "Show HN" tag.


Please at least write the README.md by yourself. It's excessively lengthy.


Do you have plans to support an extension ecosystem, such as exporting content to Obsidian or other PKM apps?


I plan to add shortcuts support so hopefully that will allow people to integrate. And also as the foundation for the next-gen Siri and MCP support. But I’d love to hear your workflow to find out what you have in mind. Please email at hi@doublememory.com or find us on discord or social. Let’s jam!


I just submitted a TinyML paper last night, focusing on creating a reproducible pipeline for model selection, compression, and deployment on constrained devices. I hope it gets accepted!


The concept is promising, but I tested it and found the performance quite poor. I used one of my Python projects for the test, which consists of about 10k lines of Python code. The model I utilized was Claude 3.7 Sonnet with thinking.

in the first conversation round, I asked Claude to grasp the overall project and initialize its memory. Unfortunately, Claude experienced a hallucination and generated an episode that included a full name entirely unrelated to my project's actual full name, as my project name is an abbreviation.

In the second conversation round, I provided Claude with the full name of my project and requested it to correct its memory. In response, Claude apologized and claimed that it now understood the full name of my project, but it did not utilize any MCP command.

In the third conversation round, I specifically asked it to use the MCP command to update its memory. Claude successfully added a new episode but failed to remove the incorrect old episode.

It wasn't until the fourth conversation round that I directly pointed out that it should eliminate the incorrect old episode, and Claude finally completed the memory initialization that should have been accomplished at the end of the first round.

I have set up the correct Cursor Rules according to the README.

At this point, it appears this project is challenging to use with natural language. I need to explicitly instruct Claude on which specific tools to call for various operations to achieve the intended outcome.

Am I doing something wrong?


I used Claude 3.7 Sonnet for the Cursor Agent when building the demo. Happy to hop on a call to walk through your experience, as I'm surprised the agent performed so poorly. daniel AT getzep.com
