Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 75 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Nelle: Browser-Only AI Agents Fail When Workflows Require Native OS File Uploaders
“This is one of the cases where if you just do, you know, browser use type stuff, you will have a bad time because it now needs to upload files. Like it just uses its native file viewer to do that.”
Nelle: Unguided AI models produce sloppy abstractions, requiring experienced engineers
“Models today do still have weaknesses, where if you let them run for too long without cleaning up and refactoring, the code will get kind of sloppy, and there'll be bad abstractions, and so you still do need humans that, like, have built systems before, know g…”
Nelle: Cursor's agent swarms broke internal GitHub Actions CI/CD pipelines
“Like, we've broken our GitHub actions recently because we have so many agents, like, producing and pushing code that, like, CICD is just, like, overloaded because suddenly it's, like, effectively we grew, cursor's growing very quickly anyway, but you grow head…”
Catanzaro: Cursor Uses Real User Activity to Improve Agents and Tab
“And this is what cursor does. Like they actually do use you know, real user activity on their platform to, you know, significantly, like, improve both their coding agents as well as Tab.”
Building a custom IDE would cost AI coding startups $100M
“If like Cursor or Devon would have to build their own VS code, that'd cost a hundred million dollars, you know? Call me back in five years.”
Scott Wu: AI is shifting from text completion tools to autonomous agents
“The first wave of generative AI is what I generally call these text completion products, right? And, you know, that makes a lot of natural sense if you think about it that obviously the interface of a language model is text completion, right? You give it a pre…”
Marimo AI Completions Access In-Memory Variables and Database Connections
“What's unique about doing it in Marimo is the fact that not only does Marimo see your code, but it sees all the variables in memory and it can also see your database connections, et cetera. So it can really provide rich Rich completions.”
Hsu: Speak mandates AI coding tools as default engineering workflow
“We try to set a culture in the engineering team where usage of these tools as much as possible and as a default path is the expectation. And in hiring We are now explicitly asking about this a lot, thinking about what are the types of people that are going to …”
Friedman: AI coding tools split into IDE evolutions versus greenfield re-imaginings
“I think like we have like two type of families of tools. One is like we re-imagine the software development. I think Bolt is there. And I think like a cursor is more like an evolution of what we already have. It's like taking the IDE and it's amazing. And it's…”
Eskildsen: Notion and Cursor agents run unprecedented search query concurrency
“Notion does a ridiculous amount of queries in every round trip, just because they can. And I'm also now, when I use the cursor agent, I also see them doing more concurrency than I've ever seen before.”
Cursor launches BugBot autofix to automatically fix flagged issues
“We actually just launched BugBot autofix, where you can click a button and or change a setting, and it will automatically fix its own things.”
Cursor launches Model Context Protocol support for Cloud Agents
“We also launched MCPs along with along with this Cloud Agent launch, launch support for Cloud Agent MCPs.”
Cursor uses Linux VM file system snapshotting to initialize agent environments
“The main default way is actually snapshotting. Like a VM, right? You run a bunch of install commands, and then you snapshot more or less the file system. And so that gets you set up for everything that you would want to Bring a new VM up from that template bas…”
Cursor plans public release of transcript-based multi-agent debugging
“There'll be some versions of this as we ship publicly soon where you can spit up an agent and give it access to another agent's transcript to either basically debug something that happened.”
Cursor disables Cloud Agents from spawning additional Cloud Agents
“We have disabled its cloud agents starting more cloud agents. So we currently disallow that.”
Reggio: Cursor adoption is uniform across Brex engineering
“It's actually fairly, fairly uniform across the entire engineering department. It's actually kind of funny, like one of our largest cursor users is actually an engineering manager.”
Nair: Cursor updates its tab autocomplete model policy every two hours
“Recently Jacob Jackson had this blog post about like, online tab, where like, you know, we're doing policy- Because there is every two hours. Exactly, like, a policy update every two hours or something”
Ubl: Cognition and Cursor shipped RL fine-tunes of open-source models
“Just yesterday, I think we saw both Cognition, congrats, SWIX, and Cursor to ship RL fine tunes of unnamed open source models.”
Landgraf: OpenVSX powers all extensions in Cursor and Windsurf
“And together with that, we also created OpenVSX, which I think now powers all of the extensions that you see running in Cursor and also Windsurf, which is also open source under the Eclipse Foundation marketplace for VS Code.”
Zach Lloyd: Warp rules differ from Cursor rules by being cloud-synced
“The biggest difference that these are is that these are sort of like cloud synced. And so you can sort of use these wherever you log in. They're sort of shareable. Across the team. And so like, this is our version of cursor's rules.”
Zach Lloyd: Warp will likely support the Cursor rule format directly
“I think we will also, by the way, probably just literally support the cursor rule format.”
Augment Code runs inside the Cursor editor and already has active users
“Yes, you can use augment inside of cursor. We actually have quite a few users doing that.”
Phase Shift's Eval Studio user interface was entirely written using Cursor
“Everything in this in the phase shift UI, this, or this eval studio UI that I showed you was written by AI. So this entire UI was written by AI, but it was not written by. Oh my God. They shipped it was written by cursor.”
Zhang: Cursor Team Contacted SGLang Over DeepSeek-V3 Support
“And when we released the DeepSeq feed story support some employee from the Cursor team Also very interested in our implementation and ask, reach out and ask some questions from us.”
McAteer: Use coding assistants to bootstrap structured prompts from raw brainstorms
“What I do, and I think what you should do is use other prompts to sort of bootstrap your prompts. So like I have it set up in cursor or in windsurf where I was telling Alessio before we started, you basically, I have like a prompt template in a prompts directo…”
Fireworks AI deployed a custom workload optimization stack specifically for Cursor
“We have a unique automation stack that is one size fits one. We actually deploy to cursor early on. Basically optimize for their specific workload, and that's a lot of juice to extract out of there, and we see success in, in that product is actually can be wid…”
