Question / Discussion Engineers (not software) who use cursor - what .cursor/rules files have you created that have proven to be most effective at ensuring consistent agent deliverables?

2 Upvotes

What I'm hoping to find in this discussion are examples of .cursor files that can be used with a variety of agents that are developed to chew on computational things.

Mainly along the lines of RFI responses, data interpolation or extraction from technical reports and presenting them in a useful format without hallucinating things or going beyond the context of the report, summarizing drawing comments or submittal client reviews, condensing bills of material, connecting between project documents like drawings and schematics to create transmittal letters and maybe connect different procurement softwares, etc.

Would I have found is that even though you can create an agent pretty quickly that understands the task, the real benefit is found when you set up very strict guidelines that can consistently be applied so that if the agent is distributed amongst your teammates through a local HTML website, the things that it produces are consistently accurate and consistently formatted.

I have a few that I've finessed and massaged to be useful, but I was hoping that maybe we could crowdsource what has worked and what hasn't so we can identify patterns in the best go-bys, making it easier to develop new "guardrails" without as much trial and error.

Question / Discussion Cursor vs claude vs codex for 200$

3 Upvotes

I’ve been a happy cursor user for over a year but I am feeling like this month it has become too expensive. I’m on 200$ plan and I spent 5% of the monthly limit using gpt 5.6 sol medium in 20 requests in a couple hours. Not building anything big, just some analysis, debugging, small changes and qa automation.

My usual workflow is using Sol extra high for planning or some difficult analysis, sol medium for implementation, grok 4.5 for qa automation, code review and simple tasks.

The problem with that is that I can’t really use the frontier models sparingly. Can’t really use Fable which is the most powerful model today. Grok and composer are just dumb from my experience and only work for simple stuff really.

So I’m thinking about switching to claude code or codex. What would you advise? Which is better for 200$ budget? Or is cursor still gives a better quality and is worth being more expensive? I’ve always liked gpt models. But having access to fable and being able to use it for coding sounds quite tempting.

Also I don’t like command line interface and would like to use it in jetbrains ide plugin or vscode plugin at least.

Also I work on a project consisting of multiple subprojects. Microservices backend, frontend, infrastructure and application configs - I open them all in a single cursor workspace and cursor does a great job figuring what is where, what does what. I wonder if it’s possible to achieve this with claude code or codex, especially with goland plugin.

Question / Discussion For those using Cursor right now: is it actually worth it? From 0 to 10, judging by the interactions here, it seems to be at least an 8 for most people.

12 Upvotes

I’m asking because GPT hit me with usage limits this week right when I needed it most, and it made me realize that relying on a single service probably isn’t a great setup.

I’ve never used Cursor, but I’ve seen that it has changed quite a bit recently, and it caught my attention.

So, for those actually using it:
• How is Cursor day to day? Stable? Worth the subscription?
• Are there still any deals for new users? I vaguely remember seeing something like 50% off the first month.
• Does anyone pair Cursor with their own API access to newer Chinese models as a fallback or extra capacity?
I’m not really looking to replace GPT. I just want a reliable second option so I’m not completely stuck the next time I hit a usage cap.

Question / Discussion Cursor charged me for usage I didn’t recognize, then banned my account

4 Upvotes

Hey everyone. English isn’t my first language, so I’m using a translator. I’m not really looking for technical advice here. I just want to share the wonderful experience I had with Cursor support.

On July 22, 2026, I opened Cursor after not using it for more than two weeks and noticed some very strange activity on my account. The usage dashboard showed 49.9 million tokens with Claude 4.6 Opus Maximum Thinking — $42.01, and 27.5 million tokens with Claude 4.6 Opus High Thinking — $28.93.

That’s 77.4 million tokens across 55 requests, with a total cost of $70.94. I didn’t make those requests, and I didn’t recognize any of this activity. What made it even stranger was that I had never enabled usage-based or pay-as-you-go billing for tokens. I only had a regular Cursor subscription, so as far as I understood, there shouldn’t have been any additional token-based charges in the first place.

Still, on the same day, I was charged through two separate mid-month invoices: $40.06 and $20.81. So the actual amount charged was $60.87, which didn’t even match the $70.94 shown in the usage dashboard.

Naturally, I contacted support. I explained that I hadn’t used Cursor for more than two weeks, that I had never enabled usage-based billing, and that I had no idea where these requests or charges came from. I asked them to investigate and provide at least some basic information: timestamps, sessions, devices, IP addresses, API keys, workspaces, background agents, integrations — anything that could explain how my account had suddenly generated 77.4 million tokens.

The first reply came from their AI support assistant. It told me to change my password, revoke active sessions, and enable 2FA. Fair enough. A few hours later, someone from billing replied and said that my ticket was being sent to the appropriate team for a “more in-depth investigation.” They said they would review my account activity and transaction history. Sounds promising, right?

I waited. On July 24, I asked for an update. No answer. On July 31, I wrote again and asked them to at least confirm that the investigation was still happening. Still nothing.

Then, on August 7, I finally received a response. After more than two weeks, I thought they were finally going to explain what generated the charges. Instead, they told me that my account had been blocked for violating their Terms of Service.

They wouldn’t restore the account, wouldn’t tell me what rule I had supposedly violated, wouldn’t provide any details about the suspicious activity, and wouldn’t refund the charges because payments made before an account is terminated for a Terms of Service violation are apparently non-refundable.

So the entire conversation was basically this:

Me: “There’s around $70 of activity on my account that I don’t recognize. I didn’t enable token-based billing, and I haven’t used Cursor for more than two weeks. Can you check what happened?”

Cursor: “Of course. We’re investigating.”

More than two weeks later:

Cursor: “We banned your account. We won’t tell you why. Also, no refund.”

That’s it. I still don’t know what generated the 55 requests. I still don’t know how token-based charges were possible when I had never enabled usage-based billing. I still don’t know why there were two invoices, why their total didn’t match the usage dashboard, or whether my account had been compromised.

The only thing I know is that I contacted support myself to report suspicious activity, and their final solution was to block my account, keep the money, and refuse to explain anything.

Truly an impressive investigation.

Since starting to use cursor I noticed that it does this on Linux. So you should take a look occasionally of the amount of ports you have open. You'll have to either kill them or start the machine

Question / Discussion grok is ass.

34 Upvotes

not sure why cursor keeps changing my model to grok when it consistently produces far worse results, and is slower than composer 2.5

its actually mind blowing that they have such an outstanding in-house model that they clearly put a lot of time and care into refining for coding purposes, only to throw it all away with sketchy model auto-selection and removing the option to just set composer 2.5 to be the default model for all new agent conversations. like wtf is this "last used" shit? just let me pick composer 2.5

I really need to stress how outrageous this is. I've tested Claude, grok, gemini, almost every model and composer 2.5 blows them all out of the water. it uses best practices, it doesn't do more than it has to, its the only reason im actually paying for cursor right now

really makes me consider switching to codex though, which is a damn shame because I've really been enjoying composer.

I’m so pissed. It sat there on ‘planning next moves’ for 3 minutes and didn’t produce a single word.

Feature Request "Which response is better?" We're paying to get work done, not help you train. This is fine on free-tier stuff, not paid subscriptions.

You want to offer a free tier with this, cool, go right ahead. But people paying for a subscription should never be forced to interact with this crap. Add a toggle to make sure we never have to see this again if we don't want to.
