r/cursor

A useful agentic change does not end when the diff appears. It ends when the system is coherent again.

I watched this exact loop last month: we asked an agent to tighten signup validation. It updated the form, the server-side validator, even the e2e test. Green across the board. We shipped. Two minutes later realized the password reset was broken.

A software change is not merely code moving. It is a shift in the requirement set.
There's a gap between the physical system (code, tests, schemas, diffs) and the theoretical system (requirements, contracts, constraints). Agents edit the former. We care about the latter.

When those two layers drift apart, an agent can satisfy the explicit task while breaking an implicit requirement nobody named and no automated check protects.

This post is my attempt to reason about that gap, and how to structure an agentic engineering harness around requirements, contracts, and deterministic feedback loops instead of just writing longer instruction files.

If you're interested, give it a read. If not, maybe let me know what I could do better!

Appreciate any feedback, and happy to partake in discussions :)

I am working 3 hours a day and fully vibe coding. Does cursor works well and maintains same performance in a month or will i face with limit reacheds and errors

So many people say they use Opus 4.7 for planning.

I’m curious: if I choose model Opus 4.7 High Thinking in cursor to create a plan, for example:

>“Create a plan for a CRUD blog feature. Follow the existing CRUD news pattern, including frontend, backend, DB migration, validation, TDD, frontend-design skills, and ui-ux-pro-max skills.”

How much would it cost to create that plan?

I want to try it, but I’m worried it might use up all of my $20 Pro plan credit.

Hey guys,

I’ve been using Antigravity PRO for the last few months as a web dev. I have a Google AI PRO subscription, which used to let me use Gemini 3 Flash basically unlimited. Sure, it would struggle with massive tasks, but as a productivity tool, it was perfect. Having the full context of both the API and the front-end at the same time meant I could easily ask it to add a new endpoint and connect it to the front-end in minutes. It made my workflow like 90% faster without dropping the code quality.

I got super used to this setup, but Google just updated the Antigravity IDE. Now, all the default models feel like absolute overkill for simple, repetitive tasks, and they completely destroyed my weekly quota in less than 10 minutes of normal use. It's unusable now.

So my question is: how are Cursor PRO's limits for models like Gemini 3 Flash? Will I actually get a decent, reliable workflow there, or am I just going to hit another wall?

Appreciate any insights!

Hey guys, I’m losing my mind trying to find an AI coding setup that can handle heavy usage on a strict $20/month budget. Claude Code and Codex burned through limits way too fast for my workflow. For a while, Google's Antigravity running Gemini 3 Flash was my holy grail, but they just updated it to 3.5 Flash yesterday and absolutely nuked the usage. I am literally getting throttled after 5 prompts now.
I’m looking at switching to Cursor Pro next, but I’m super paranoid about wasting another 20 bucks just to get locked out. If you use Cursor heavily on the $20 tier, how long do those "fast" premium requests actually last you? More importantly, once you hit the cap and drop to the slow tier, is it still usable for continuous coding, or does it become painfully slow? Would love some honest feedback before I pull the trigger.

Cursor is a frontier lab now I guess

Hi all, i am kind of new to claude world, i am building a website, and i have used claude code, and i also have used the claude chrome extension (the one that controls the browser tabs). I feel a bit stuck now that i am in the most complex steps with databases, things dont work well and i think i am in a loop with claud the last days. Today i got an advertisement for cursor and i want to ask for your opinion, thanks!

I’m curious to see what everyone is using for which cursor mode and if anyone thinks composer 2.5 can take the place of any of the models I’m currently using:

Ask: usually Sonnet 4.6, sometimes GPT 5.5

Plan: Opus 4.7

Build: GPT 5.5

Since it's been out, how really is it in your real-world codebases. I am extremely skeptical of benchmarks and I trust people's "feel / taste" of it way more.

Please be detailed, like what programming language, what size codebase, what kind of software you're making, and comparison against GPT-5.5 and Opus 4.7

I’m working on a project where I’m using an internal spreadsheet from our Accounting team with different scenarios in Oil & Gas Revenue to import the data to our DB tables

What are some ways to create a program, md, etc? I’m fairly new but would like thought process of how to construct this

I can't prove it, but I'm 99% sure they distilled Claude to train this new model. It talks a lot like Claude, walks through conversations in a similar style, and is way better at following instructions - just like Claude.

ok so i'd basically trained myself to use gpt 5.5 for anything that wasn't trivial. like if it touched more than one file or needed to actually understand the codebase, that was the default. got used to the quality and stopped questioning it.

tried composer 2.5 mostly because i was curious and didn't want to burn credits on another "fix this lint error" loop.

and it's... good? like annoyingly good for how fast it is.

stuff lands in the right files, doesn't rewrite half the module for no reason, picks up our weird patterns without me pasting three examples every time. i'm not sitting there undoing agent slop as much.

also it's fast. which sounds dumb until you've been staring at a spinner between turns for 20 minutes on a refactor.

and yeah: CHEAP. i know that's boring to post about but when you're in cursor all day it adds up. gpt 5.5 habits get expensive fast.

still use the heavy models sometimes for truly cursed bugs. but for normal work — features, fixes, "why is this broken" — i've been leaving composer 2.5 on and not switching back.

anyone else or am i just in a good week

Hey guys,

I am currently using the 20 dollar codex plan and never hitting limits on like 5.5 medium with full weeks of coding. And really good results. But one other subscription I thought about is cursor plus or something. The 20 dollar one.

Can you guys explain what the usage limits are. Relate to other plans maybe cause I read the docs, there are two usage pools, composer 2.5 is also on par with opus 4.7 and gpt 5.5 and really cheap. and also separate usage for the other sota models.

So how are the limits? Are they acceptable? What would you say if I code like 3 hours a day, not too heavy usage but like I dunno 20-40 prompts a day, will the plus plan satisfy me?

Or is cursor another grok. (unusable)

Thanks for the info in advance:)

I’ve been using vscode studio for a while now. I noticed how Zed editor has made it easy to integrate MCP servers with the technology being used now.
Do you think it’s worth paying for an Editor? For example Cursor, Antigravity and Zed?

I keep seeing people talk about cloud agents like they’re the future of development workflows, but I still can’t tell if they’re genuinely useful or just another AI productivity layer.

For those using them daily, what are you actually delegating to cloud agents?

• Code reviews?
• Research?
• Long-running tasks?
• Refactors?

Trying to figure out where the real value is beyond demos.

I have not been able to use Opus 4.7 for a few hours. I guess I Just need to wait or is there any workaround? will auto be as effective as Opus 4.7? how does Cursor pick which model to use in Auto? I believe it will use the cheapeast model all the time?
