harness
Everything wrapped around the model that turns it into an agent: the prompt it gets, the tools it can call, how files and context are fed in, what happens with its output. Same model in two harnesses behaves like two different products.
Where it comes up
Cursor 201
“to not going to kill you with slides, but um you know, if you've if you've done a Cursor 101 in the past, you're looking for some more advanced workflows, cool. This is definitely the right place for you. Um you know, if you are looking to…”
Refactoring Legacy Codebases
“out, especially in a multimodel harness like cursor where we optimize each model inside of our harness for using these tools uh and these these models, it's worth giving a shot because you'll have a drastically different experience than if…”
How Cursor uses Cursor
“But as you can see, uh we expect is this this graph kind of continue climbing, right? As as we continue to add more engineers to our team, build out more products, um but then also continue to just improve our harness to make sure that um a…”
Training Composer 2
“Uh but I certainly could see in the future we would add that. And then think some questions about overall team structure and how we do stuff. Who owns the agent harness? Is this driven by the product team or the research team? And similar w…”
Cursor 101
“And if what you're really here for is to understand how to get the best results uh from LLM's if if you work with them. I think it really comes down to two things. Provided that you're using a modern harness like Cursor, um the the two main…”
PRD to PR
“what's actually happening with Cursor. Because, you know, there's a lot of people that think um you know, Cursor's just this kind of, you know, client desktop app and we just, you know, send your prompts directly to the model providers um a…”
Cloud Agents
“Hey everyone. My name is Emily and I'm an engineer on the growth team here at Cursor. And today we will be presenting about cloud agents, which is agents that run in the cloud and they keep going when laptops are actually closed. And they l…”
Cursor 101
“Um There's something this idea called an agent harness, which basically, when you when you hit enter, when you write a prompt and you hit enter, it's what happens in between that moment and when the model actually receives it. And, Cursor h…”
Cursor 2.0 Launch
“agent and harness inside of cursor, it knows when you put a link, you probably want to go read that link, right? So, you can see up here it went and it saw that link. It went and read the content of that links. Uh, now the way plan mode wor…”
Cursor Automations
“machine for you, but basically like the cloud opens up all of these different possibilities. It lets you access your agents kind of anywhere in the cursor ecosystem. It gives you access to all of cursor's tools, our harness, which is the be…”
Cursor for Data Science
“harness that's optimized for every model and works well with real kind of live workflows. And you'll see that today really throughout the demo because this is where we're going to focus most of our time. But under the hood, what's powering…”
Cursor Admin Guide
“you know, cost can be a consideration there. Um Now, there's also another side of the coin is where you know, teams do want to make sure that they're or admins do want to make sure their teams do have access to the best models. And so, ther…”
Cursor for Java Developers
“cursor is a harness lab. So each time all the model providers before they provide their latest and greatest model, they actually send it to cursor for cursor to play around and test it out and build a very good hardness for each in specific…”
Cursor for Knowledge Work
“Awesome. So, this is our Cursor for knowledge work workshop, where we'll be doing a high-level introduction to Cursor, going through a demo of some top use cases we recommend for you folks to try out, and then George will be talking about h…”
Cursor for Support Teams
“seen uh sorry I'm looking at the wrong place is um the ability to basically harness the agent to instead of just going at and changing things and writing code and editing files um give you a pretty detailed markdown that's going to explain…”
Cursor x Slack
“cursor bug bot or building our own agent team to do that review ourselves. And so, I want to share some notes from the field, and I think what's interesting here is that in each distinct phase, there's a lot of different collaboration and c…”
Model Selection & Token Efficiency
“And then Omkar asks, "Are there any tricks to provide a memory to the agent?" Yeah, absolutely. So, under the hood, like when you make a request to an LLM, there is no memory, right? So, it's actually Cursor's agent harness, or if you're us…”
