Hi all. I’m new in this forum, but I’ve been facing a problem. When I’m using Cursor, I see this screen many times:

And I loose the last part of chat, and I have to reopen Cursor. Is there a way to avoid this?

My config:

TIA,

Hey, please check this:

[0.47.5]The UI is very slow so that I can not work with it!

I think this issue is related to a large amount of chat history in your project. You can try renaming your project and opening it. If that helps, then the cause is clear. If your chat history is important to you, you can try exporting it using this extension:

Hi @deanrie thanks for the answer. Just one question: If I rename my project and opening it I won’t have the previous chat, is that correct? But in case I need the previous chat, (not the whole chat, but the most recent, ie: today’s chat) how can I do to delete older chats?

[T1000]

Cursor doesnt have partial deletion feature etc.

Current workaround as Dean mentioned is to rename the folder.

Some user (if you can still open the project) use SpecStory extension to export the chat History. (3rd party extension)

If you are familiar with sqlite you could access the db directly with closed Cursor and extract data you need.

Otherwise likely for now no other way than losing history on rename.

I’ll add to what @T1000 said.

Most users also run custom instructions to build a memory bank or documentation, which the agent can then reference as needed instead of relying on context in chats. Which do not use the full context window of the model.

You can view context sizes used here: Cursor – Models

Personally, I delete chats multiple times a day and only use a single chat at any given time. I’m also on macOS.

I used SpecStory for a bit, but with the way I have rules and prompts set up, my agent keeps track of its own memory bank and documentation. Each time I start a new session, I use the summary feature, and with the prompts in place, I simply need to prompt it with:

Pick up where the last agent left off.

Cool thanks, didnt see that the context was explained more on the pages!

[Kleyber]

As I can see, I have a lot of things to learn… how to to this, in my case? Is there a way where I can see what I have to do?

TIA,

The primary rules are in Cursor Settings (very top right gear) > Rules > User Rules. Anything you put there will be sent with every message you send.

You also have Cursor Rules, which you create. Cursor makes setting it up more manageable in Cursor Settings > Rules > Project Rules.

When you add a rule there, it will create a folder with your project’s root names.

.cursor/rules/

Any new rule file will be put there.

Read up on it here: (Use the AI Search to find answers; it works very well.)

Cursor – Rules for AI

There are plenty of systems here that work very well. Check out RIPPER-5.

I’m in the process of building a bot on Poe.com that will help with this. Once complete, it will have access to my collection of prompt engineering white papers. I’ll share it here once it’s finished.

Thanks for your answer, @mikes-bowden. About rules I’m already using it. What I’m talking about is about what you said:

How did you do that? Maybe this is a solution to my problem.

I repurposed the Cline Memory Bank to work with my system.

It’s not currently ready to share; I’m still working out some issues with how it works with 3.7 or, really, the way 3.7 loves to ignore prompts.

Once it’s done, I’ll release it here on the forums.

[Kleyber]

Thank you!!

[mikes-bowden]

Any time.

I’d recommend loading your rules and all of the prompts for the memory bank in either Claude Projects, Poe.com, with context management disabled, or Open WebUI with context set to max so the LLM can see everything. ChatGPT Projects doesn’t load everything into context; it uses RAG instead. If you use Open WebUI, just be sure that if you attach text files, you enable Using Entire Document.

Then, simply tell it you want to incorporate the Cline memory bank into your platform, give it the documentation for Cursor rules and User Rules, and then have it handle revamping everything.

I also create my own agents instead of relying on the ones crafted by Cursor. Not that theirs aren’t great; I simply prefer having more control (). I created a multi-mode agent that uses inspiration from the RIPPER-5 prompt that @robotlovehuman released, which is excellent on its own. I also created a documentation agent. I’m pretty much set on almost everything I do between those two. The multi-mode agent has seven primary modes and two sub-modes, which are used with a few of the primary modes, giving a total of 14 modes that it can swap between on its own, less the documentation agent, as Cursor cannot currently swap between agent modes, at least as far as I know.

The sub-modes help enforce autonomous mode when I can’t babysit it or interactive mode when I want to actively participate in it or when it might need my intervention.

Let me know if you have any other questions.
